Definition of a Mole

Definition of a MoleThe rate of reaction is a common measurement used in experiments. It can be measured in a variety of ways, such as the coefficient of rate constant, the change in rate during the experiment, the coefficient of friction and so on.It is used as a measure of how much work is being done in a chemical reaction, such as in the example of morality, moles per liter, mole fractions, and so on. Chemists also use it in a more complex sense. For example, by the time the reaction has started the number of atoms that have been transformed has increased.One way to measure the rate of a reaction is to divide the volume of the substance by the molecular weight of the substance, or the fractional number of atoms. This means that the amount of one atom divided by the total number of atoms, known as the mole. There are a few simple definitions of the mole as well as the SI unit used to denote it.It is a measure of how much mass an object or substance contains, for example by the numb er of one molecule. The number of atoms divided by the total number of atoms, also known as the mole. In this article the SI unit is abbreviated moles. A mole is also called mole fractions.It can be used to refer to the rate of change of one element over a long term, for example to predict how things change over time. The mole is also commonly used to indicate the mass of a substance. The mole of a substance can also be written as M mole of c, where c is a constant. A chemical equation can then be solved to determine the mass of the substance.One of the units of science used in chemistry is the mole. It was invented by Alfred Ohler in 1867. In chemistry, there are several units used in different areas of the field.There are the mole, which are the most commonly used term expression for the mass of one element, and which is different from the mass of one electron. The mole is used to describe the mass of one molecule, and not to refer to the mass of one electron. The mass of an atom is referred to as the atomic mass.The mole is a measure of the mass of one element, and not of the mass of one electron. There are many other units used in chemistry and they are very important in studies of reactions.

3 Common Career-Wrecking Stories We Tell Ourselves (and How Not to Derail Yourself) - Introvert Whisperer

Introvert Whisperer / 3 Common Career-Wrecking Stories We Tell Ourselves (and How Not to Derail Yourself) - Introvert Whisperer 3 Common Career-Wrecking Stories We Tell Ourselves (and How Not to Derail Yourself) Introverts aren’t the only people to create stories about their behavior in order to rationalize it and make it “OK.” We all love rationalizations soooo much; we don’t go a day without a few. The problem is that if we keep listening to these career-wrecking stories about what’s going on in our career, we won’t get the pay and recognition we deserve. Are you mysteriously stalled out in your career? You might want to pay attention to some of these stories I’ve heard Introverts tell to see if they match up with you. I Don’t Speak Up in Meetings Because I’m Polite by Letting Others Talk Don’t fool yourself. We were all taught manners; whether or not people are polite or courteous is another matter. If everyone took that point of view, no one would talk. You will be viewed as passive and not gain the respect needed to be supported for upward career growth. Solution: First, lose the story. It’s simply not true. Second, yes it’s hard to make yourself speak up, but you need to. Consider simply injecting your opinion about the topic being discussed, even if that opinion has been offered up a dozen times. It’s your opinion and it has as much value as anyone else’s.       My Industry Has Bad Management Because I Have a History of Not Getting Along with Management But I Get Along With Everyone Else The joke’s on you for not developing strategic relationships with your management. You might not like to follow their direction, but guess what? They’re in charge. And until you are, it’s their opinion that will sway the direction of your career. Solution: If you can have good relationships with most people but not your management, that alone is an indicator that you have work to do. Spend time with your management. Figure out what’s important to them and then deliver well. Then, communicate what you’re up to. Don’t make your management pull things out of you about your stellar performance â€" because they won’t. (Like this thought? Tweet it!) Office Politics Doesn’t Affect Me So I Stay Out of the Fray and Focus on My Work. Wanna bet? You can choose to ignore the politics of your organization but it will impact you. A big part of your ability to get the support you need to make your star rise is how well you influence those around you at all levels. Politics happens anytime a group of people assembles. It’s about who can make decisions, who can influence who along with rewards and punishment. Solution: Don’t ignore who has influence other than management. These are good people to form alliances with. Every group has them. It’s simply a person who has chosen to form relationships â€" therefore gain support â€" to advance their agenda. You can learn from this type of person as well as bask in the glow of their organizational pull. Go to top Have you been telling yourself one of these stories? Share your experiences in the comments!

What is it Like to Attend Canisius College

What is it Like to Attend Canisius College The tutors behind Varsity Tutors are not just here to teachtheyre sharing their college experiences as well. Victoria lives in Buffalo and is a 2013 graduate of Canisius College. She holds a bachelors degree in biology and specializes in algebra tutoring, anatomy tutoring, and biology tutoring. Check out what Victoria had to say about her time at Canisius College: Describe the campus setting and transportation options at Canisius College. Victoria: Canisius College is located in the city of Buffalo, New York. Throughout my years in Buffalo, I have had the pleasure of watching the city transform into a great place for young adults to live. The campus is located on Buffalos subway line, which extends downtown through a restaurant and nightlife scene, all the way to the waterfront where the Buffalo Sabres play at First Niagara Center. How available are the professors, academic advisers, and teaching assistants? Victoria: I personally had a wonderful experience with Canisius Colleges faculty and staff, as the student-to-faculty ratio is kept close to 9:1. Teaching assistants are available to help students in labs, but nearly every course is taught by a professor. I felt as if both the professors and the support staff bent over backwards to assist me in all ways possible. How would you describe the dorm liferooms, dining options, location, socialization opportunities with other students? Victoria: I lived on campus for three years, and I thoroughly enjoyed the housing options. In comparison to most schools, Canisius College has spacious, clean, and comfortable choices. The majority of the campus is connected by underground tunnels, which makes it easy to get from the library to your dorm to the dining hall without having to go outside in the winter months. Which majors/programs are best represented and supported at Canisius College? Victoria: Canisius College has a wide range of programs, with strong science, business, and education programs. I chose to study biology, as I wished to attend dental school, and after almost earning my D.D.S., I can attest to the fact that Canisius College prepared me extremely well for graduate school. Canisius College also has an extremely strong accounting program, and it offers graduate courses in a variety of fields. How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Victoria: With less than 3,000 undergraduate students, it is easy to assimilate and become comfortable when living on the Canisius College campus. Greek life is not a huge component of social life, but students often become very close with people within their majors, as well as people who live close to them in campus housing. How helpful is the Career Centerand other student support services? Victoria: The career center is a fabulous tool. If you are interested in the sciences, they provide great resources for mock interviews and resume building. My friends in the business school had great job offers right after graduation, and the network of successful Canisius College alumni in the Western New York area give great opportunities to recent graduates. How are the various study areas such aslibraries, the student union, and dorm lounges? Victoria: The Canisius College library was my home away from home, and I actually chose to continue to study there throughout my graduate school career. A Tim Hortons (local coffee shop) was added to campus a few years before I attended, transforming the first floor of the library into a fun social environment. The second floor is designated for quiet study, and the basement offers various group rooms for group projects and activities. There are other study areas throughout campus, and finding a favorite spot never proved difficult. Describe the surrounding town. Victoria: One of my favorite parts of attending Canisius College was getting to know the city of Buffalo. Buffalo has phenomenal restaurants, unique neighborhoods, and friendly people. Elmwood Village and Allentown offer a more hipster vibe, with boutiques, coffee shops, quirky bars, ethnic cuisine, and plenty of annual events. Canalside is the recently renovated waterfront, which includes tons of free fitness classes, concerts, a bike trail, and beautiful views. Chippewa Street is the nightlife district, which is open until 4:00 A.M. The city continues to grow and thrive, making it a fabulous place to live. How big or small is the student body at Canisius College? Were you generally pleased or displeased with the typical class sizes? Victoria: The student body is relatively small compared to most colleges. Coming from a small high school, I was pleased with the typical class sizes, which generally ranged from 18 to 24. Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Victoria: My favorite professor taught organic chemistry, and volunteered to be the faculty member for a club that my friends and I started and funded. As Canisius College Endurance Athletes, the school sponsored us to run in local 5Ks and half marathons. I ran my first half marathon with my favorite professor on a weekend trip to Cleveland. Being able to form connections with faculty members outside of class really enables you to get to know each other, making recommendations for future job opportunities or graduate school easy to obtain.

She specializes ina multitude of subjects including SAT prep tutoring, ACT prep tutoring, Physics tutoring, and Writing tutoring. See what she had to say about her school: VT: Describe the campus setting and transportation options.How urban or safe is the campus?Are there buses or do you need a car/bike? Sarah: It's very easy to get around campus for most students. It's possible to walk from one end of campus to the other in under ten minutes. The main campus is very flat, and there are many walkways so students can take more efficient routes. Bikes are common, and there are plenty of bike racks. There's also Campus Circ, a bus that students can take to get around campus. It is generally on time and is used by many students. VT: How helpful are the academic advisers? Sarah: Each freshman is assigned an academic advisor at the beginning of their first semester. These advisors are usually deans, and are especially useful when one needs general information or advice about scheduling, courses, or teachers. They also help students lay out a four-year plan to ensure that all requirements are met for graduation. After students choose a major, they are assigned a major advisor who can provide more specialized insight. Generally, these advisors are quite available and willing to help when students seek advice. VT: How would you describe the dorm life? Sarah: The dorms are really nice- they're clean, spacious, and (with the exception of a couple of dorms) recently renovated. Maids clean common areas within suites on at least a weekly basis. Students can request singles, doubles, or triples, and there are accommodations for special needs. The dorms have large common rooms, as well as study rooms, and are conveniently located. Some suites have balconies, many have Tempurpedic beds. They're generally considered to be luxurious. VT: Which majors/programs are best represented and supported? Sarah: Wash U's most popular majors include Biomedical Engineering, Biology, Philosophy-Neuroscience-Psychology, Anthropology, and Mechanical Engineering. BME, PNP, and Biology are especially well-supported. VT: How easy or difficult was it for you to meet people and make friends as a freshman?

With the combination of the summer programs and freshman floor bonding, it's easy to branch out and make lots of friends as a freshman. VT: How helpful is the Career Center? Sarah: The Career Center can be quite helpful. It frequently holds workshops to help students find internships, work on their resumes, or learn interview skills. It's easy to make appointments and has a centrally located office. VT: How are the various study areas such aslibraries, student union, and dorm lounges? Are they over-crowded, easily available, spacious? Sarah: There are lots of study rooms in the dorms and scattered around campus. There are several larger libraries on main campus, and many of the buildings include small libraries. There are meeting rooms and classrooms that can also be used for study sessions. Many people study in dining areas both on central campus and in dorm areas. There is no shortage of study space on campus. VT: Describe the surrounding town. What kinds of outside establishments / things to do are there that make it fun, boring, or somewhere in between?To what extent do students go to the downtown area of the city versus staying near campus? Sarah: St. Louis has a lot to offer. Wash U is right next to a large park, Forest Park, that has everything from an art museum to golf to a free zoo. Many students live in an area adjacent to campus that is off of the Delmar Loop, a stretch of a few blocks that has many great restaurants, stores, bars, and a movie theatre. The larger city has tons of great attractions, such as the Arch or City Museum. VT: How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Sarah: There are about 7,000 undergraduates. I usually know one or two people in each of my classes, and always run into a few people when walking around campus. However, its big enough that there are tons of new people to meet. It's a great compromise between familiar and new. VT: Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Sarah: I took General Chemistry my freshman year. The professor was great, a really talented teacher whose enthusiasm for teaching was obvious in his classes. The first day of class, he called on individual people by name from the audience of over 300 students. One of his last classes fell just before the holidays, and he came in that day in a Santa suit. Even though the course is over, he still greets many of his former students. In addition to these things, I found the course incredibly valuable as it really pushed me to work harder and allowed me to realize that I was capable of handling the level of difficulty presented by the class.

8 Expert Tips for Improving Spanish Reading Comprehension

8 Expert Tips for Improving Spanish Reading Comprehension Suzy S. Struggling with Spanish reading comprehension? Here are some helpful tips from Honolulu tutor Jinan B... Are you intimidated by texts, magazines, or books in Spanish?  Do you feel overwhelmed at the thought of reading and understanding written Spanish? The following tips will allow you to increase your Spanish reading comprehension and help you feel assured as you navigate new linguistic territory. 1. Notice the title and any photos or graphics in the text. These things will give you an idea of the style and content of the text. Improving reading comprehension in Spanish is like becoming a detective, and things like the title and images are your clues! 2. Draw on your own experience with and knowledge of the topic. Its likely the reading selection may cover some material that you already know. Thinking about keywords and points that the author may address, based on your prior knowledge of the topic, will increase your ability to decode the text in Spanish. 3. If there are reading comprehension questions attached to the text, read through the questions first so that you can look for the answers to the questions as you read. This will increase your engagement and understanding of the text. Knowing the questions ahead of time also gives you an idea of what the main points of the text may be, since the questions are often centered around general comprehension. 4. Get a gist. Skim the whole text to get a basic idea of the meaning. Dont worry about reading it thoroughly yet or understanding everything. Then, as you read it more in depth, you can scan each paragraph before you read it more carefully. 5. Consider the context of the text. Depending on where the story takes place, if its literature, you might expect to see informal or formal language. If its a news article, you might expect to see clear facts and details presented. Understanding how the author might convey the information allows you to anticipate the text and increase your comprehension. 6. Use cognates. Cognates are ever-helpful words that sound similar in Spanish and English and often share the same Latin root. If youre struggling with understanding a passage, try to determine what you already know simply from finding the cognates. (Note: Be wary of false Spanish cognates!) 7. Watch out for figurative language. Often, when you first start to read in a foreign language, you can forget that not everything is intended literally. Figurative language can be complex to grasp since the expressions are usually not equivalent in Spanish and English. However, if you anticipate some use of figurative language, it can reduce the amount of confusion you encounter with the text. 8. Use your knowledge of grammar. Understanding how the sentence is constructed can help you understand the meaning. Identify the subject, predicate, any conjunctions, direct and indirect objects and prepositions, and prepositional phrases. This is especially helpful if you encounter a wordy and complex sentence with many parts. Breaking it down can be the key to comprehension! You will find that the more you  practice using these tips while reading Spanish, the more your reading comprehension will increase. You can also read a text before your lessons: use the strategies above to gain as much understanding as possible, and then go over it with your Spanish  tutor  to further increase your Spanish reading comprehension. May your reading time be productive and fun! Jinan B. tutors in Honolulu, HI.

Five Kingdom Classifications Online Biology Tutors Tutorpace

Five Kingdom Classifications Online Biology Tutors Tutorpace In 1969,R.H.Whittaker proposed the five kingdom classification. He classified the living organisms into five kingdoms. The criteria used for classification are a. Cell structure b. Thallus organization c. Mode of nutrition d. Reproduction e. Phylogenetic relationships. The five kingdoms are Kingdom Monera, Protista, Fungi, Plantae and Animalia. Kingdom Monera:-The members are prokaryotic and microscopic organisms. True nucleus and membrane bound organelles are absent in these organisms. Kingdom Protista:-It includes primarily unicellular aquatic eukaryotic organisms. The cells of the protists have true nucleus and other membrane bound organelles and non-membranous organelles. Protistans Kingdom Fungi:-It includes eukaryotic, multicellular, heterotrophic organisms. Yeast is an exceptional fungus which is unicellular. Kingdom Plantae: It includes all plants. They are autotrophs,Some plants are partially heterotrophic such as insectivorous plants and parasites. It includes multicellular algae, Bryophytes, Pteridophytes, Gymnosperms and Angiosperms. They are primarily producers on lands and are immobile .They have cellulosic cell wall. The life cycle of plants exhibit alternation of generation. There are two distinct phases In the life cycle of plants-the diploid sporophytic phase and the haploid gametophyticphase. Both of these phases alternate with each other and this phenomenon is called alternation of generation Kingdom Animalia: It includes multicellular heterotrophic eukaryotes. The cells are without cell wall. They directly or indirectly depends on plants for their food. They digest the food in an internal cavity and store it as glycogen or fat. They have a definite growth pattern. They grow into adults with a definite size and shape. They are holozoic and mobile. They exhibit heterotrophic mode of nutrition.
