Common Chemistry Formulas That Are Used in the Laboratory

Common Chemistry Formulas That Are Used in the LaboratoryThe most common chemistry formulas or compounds that are often used in a research experiment or laboratory is alcohol. Other common laboratory objects are alloys like silica glass, sulfuric acid, or o-cyclic carbonates. One of the most common sources of the compound are the methods used to prepare liquids for laboratory usage.The most common laboratory substance is known as ammonia. Ammonia has a boiling point of 362 degrees Celsius. Ammonia is prepared by combining nitrogen with organic compounds in the laboratory such as acetone or ethanol.An important compound that is frequently used in the laboratory is acetic acid. It is another product of the formation of nitrogen dioxide gas in the laboratory. These gases are often consumed as waste products in a laboratory setting. Acetic acid is primarily used in the chemical production of sugarcane and medical purposes.The next common laboratory ingredient is sulfuric acid. This is a compound that is commonly used in the study of the catalytic oxidation of hydrogen. The reaction occurs when hydrogen is reduced to oxygen. It is important to note that the separation of nitrogen in the laboratory is regulated in order to make sure that there is no toxic gas emitted by the chemical production. Also, when sulfuric acid is used it is usually in the form of crystals or tablets.Nitric acid and alcohol are common substances used in the laboratory as a catalyst and a-cyclic carbonates. o-cyclic carbonate is a compound that can react with water, form complex organic compounds, and perform chemical reactions with other chemicals. Nitric acid is known to dissolve metals and neutralize acids.Glass is another common component in a laboratory. Glass can be used to create or remove barriers in laboratory experiments. When used in the laboratory as laboratory material, glass often comes in smaller particle sizes than it would if it were manufactured in another setting. It can be used in a scientific experiment to measure properties that would not be obtained if the laboratory material was made in another setting. Glass can also be used to create liquids in the laboratory. You can actually use the glass as a vial for liquids and then use it to add solutions to determine how well the substance will react with other substances.

Dividing Matrices

Dividing Matrices Dividing matrices cannot do directly as usual division. Dividing matrices is similar to dividing mixed fractions. As we are doing in dividing mixed fractions find the inverse of divisor matrix and multiply with the matrix in the numerator. If A and B are two matrix then A/B = A (1/B) = A B-1.B-1 is the inverse of B. Actually we dont divide the matrix; it can be done by multiplying with the inverse of matrix. The following examples help you to understand the division of matrices. Example 2: Explain the steps involved in matrix division. Solution: Let us assume two matrixes are A and B To divide two matrix B/A We cannot divide the matrix directly To divide matrix B/A, first find out inverse of A And then multiply with matrix B. The inverse of A can be found by swapping the position of matrix and divide everything by the determinant. After finding the inverse of matrix B, multiply with matrix A. While multiplying matrix we need to do the dot product of rows and columns. The final matrix is division of B/A.

Online Square Root Graph Tutors

Online Square Root Graph Tutors Square root function is a function which is expressed under the radical sign . Square root of a function or an expression means that it is raised to an exponent of 1/2. Square root functions can be graphed on an X-Y coordinate plane and we can also find the domain and range of the given function. To graph a square root function, we can plug-in numbers in the place of the variable x and find the function or the y value for those numbers and plot the points on the plane. Example 1: Graph the square root function, y = x. The function, f(x) = x is also called as the parent function since other square root functions are derived from it. Let x = 0, then y = 0= 0. Coordinate point is (0, 0) Let x= 1, then y= 1 = 1. Coordinate point is (1, 1) Let x= 2, then y= 2= 1.41. Coordinate point is (2, 1.41) Let x = 3, then y= 3= 1.73. Coordinate point is (3, 1.73) The graph looks as shown when the above points are plotted Example 2: Graph the square root function, y = (x 1). Since the function is (x 1), hence the graph of y = x shifts 1 unit to the right. Let x= 1then y= (1- 1)= 0.Coordinate point is (1, 0) Let x= 2, then y= (2- 1) = 1. Coordinate point is (2, 1) Let x= 3, then y= (3- 1)= 1.41. Coordinate point is (3, 1.41) Let x= 4, then y= (4- 1)= 1.73. Coordinate point is (4, 1.73) The graph looks as shown when the above points are plotted.

4 Reasons for Pursuing an Online Degree for Career Advancement - Introvert Whisperer

Introvert Whisperer / 4 Reasons for Pursuing an Online Degree for Career Advancement - Introvert Whisperer 4 Reasons for Pursuing an Online Degree for Career Advancement Professional development has become increasingly important in today’s highly competitive job market. In order to be considered for promotions and better jobs, candidates must demonstrate the willingness to sharpen their skillset. The most common method of advancing your career is to get a degree. Whether that is a bachelor’s degree to become a full-time associate or a graduate degree to move up the management ladder, a degree has been shown to lead to more career options and higher salaries. The problem for working professionals is finding the time to complete a degree while still balancing a full-time job. Scheduling on-campus classes around your busy work schedule can be exhausting. One increasingly common degree path for working professionals is enrolling in an online degree program. Online degrees allow you to pursue higher education while working full time. Here are four of the biggest benefits of using an online degree to advance your career: #1: Don’t Put Your Career on Hold The biggest benefit of an online degree is that it allows you the opportunity to continue working while pursuing a degree. Most on-campus degree programs have a considerable time commitment that forces most students to either dial back their time at work or put their career on hold completely. This can lead to losing valuable work experience and income. In contrast, online programs today are often designed with the needs of the working professional in mind. In some instances, your employer may even offer tuition assistance for a degree program. Taking online classes while working can also give you the opportunity to apply the skills you’ve learned in your coursework to the workplace immediately. #2: Flexibility and Convenience   An online degree can offer a degree of flexibility that on-campus degree programs simply cannot match.  Most online programs are asynchronous, which means that the classes are self-paced. The advantage here is that you can access course lessons and materials whenever you have free time. While you may be completing lessons after work hours, the asynchronous format of online classes frees you up to perhaps read a lesson before work, or use your lunch break to complete an assignment. This can help to maintain free time after a long day at work. Taking classes on campus while working full time limits you to night classes. Night classes can under-utilize the small pockets of free time that you have during a typical workday. #3: Customizable Learning Environment   Another huge benefit of online education is the ability to customize your learning environment. With an on-campus degree program, you are most likely going to be in a classroom for the majority of your courses. With an online degree program, you can choose where you learn. Some people thrive in a comfortable, relaxing environment while others may prefer a more traditional workspace. Many people work best away from home, and coffee shops and libraries often offer wireless internet which would allow you to access course materials there. Whatever your preference is, the key to a productive learning environment is to balance comfortability with the ability to stay focused. #4: Perfect for Introverted Professionals   Online degrees can also offer a less threatening classroom environment. There are many professionals looking to advance their career, who have a more introverted personality, that are not comfortable participating in class discussions that are commonplace in on-campus degree programs. This is where an online degree can be a good fit. With the online course format, most of the interaction with your professors and classmates is through the web. Discussion boards are one of the most common methods of sparking the class discussion. This is a much more comfortable method of participating in class for introverts. This less threatening environment can allow you to come out of your shell and enrich your learning experience without the fear of participating. It is clear that getting a degree can be a pivotal stepping stone for advancing your career. Online degrees have become increasingly more viable and respected in the business world. The flexibility and convenience of these degree programs allowing professionals the opportunity to work full time while pursuing a degree is something that simply cannot be matched by on-campus degree programs. This coupled with the ability to customize your learning environment and the limited face-to-face interaction means that online degree programs can be a fit for all personality types.

Middle School Parent-Teacher Conferences What to Ask

Middle School Parent-Teacher Conferences What to Ask Middle school can feel like an entirely different beast from elementary school, with teachers for every subject, a larger school, and often more extracurricular opportunities not to mention the major personal growth your child is going through! Weve already gone over what to ask at high school parent-teacher conferences, but here are some topics to go over when you meet with your childs teachers for middle school parent-teacher conferences: 1. Your childs academic progress One of the most important topics youll cover is your childs academic progress, including both strengths and weaknesses. Youve made your own observations at home and from what your child has told you but the teachers perspective can help round out your own. What are specific concepts, units, or learning styles has your child has taken to? In which areas does your child struggle? The teacher can articulate academic accomplishments and challenges in a different way than your child might. 2. Grade-level expectations Ask the teacher how your child fares according to grade-level expectations. This is extremely helpful if your child is thinking about taking accelerated classes, like honors, and potentially AP and IB courses later on in high school. Similarly, does your child need additional support to reach grade-level goals, like summer school or after-school help? Talking with the teacher about grade-level expectations can be very useful in seeing where your child can direct his or her attention academically, but remember that grade-level goals arent necessarily the end-all be-all. Simply use them as a guideline and pay attention to all factors. 3. Class policies Every teacher has a different way to run his or her classroom, with some overlaps with other instructors in the school. Discuss this teachers classroom policies, as well as classroom norms. You might also ask if there are any opportunities to make up tests or extend due dates if your child is absent, for instance as well as what the major components are of your childs overall grade in the class. Especially when your child is transitioning to middle school (with up to seven teachers a day versus just one or two!), having this conversation can help you and your child implement and organize specific study strategies for each subject. 4. Assessments and long-term projects Middle school assessments can feel more serious (and they often are!) compared to elementary school projects and tests. Ask the teacher how your child will be assessed and given percentages or letter grades. In what ways will your child be asked to demonstrate his or her growing knowledge? Will there be any long-term projects, like a science fair, research papers, or lengthy writing assignments with bigger timelines that would benefit from being broken down into more manageable parts? Knowing about these ahead of time is helpful so you can support your middle schooler at home. 5. Tips and resources End the conversation by going over what you or your child can do outside the classroom to make this middle school experience more successful. The teacher will likely be able to offer study tips that have worked for past students, as well as outside resources, including book recommendations, online learning tools, or events in the community that might be of interest to your child. Depending on how your childs particular middle school works, you may not get scheduled opportunities to meet with every single teacher your child sits with during the school day. Instead, you may just meet with a homeroom teacher or a teacher in one of your childs major subjects. If youd like an additional meeting with a specific teacher or have a specific concern, email or call the school to set up an appointment with him or her. Any topics you want to know more about? Let us know! The Varsity Tutors Blog editors love hearing your feedback and opinions. Feel free to email us at blog@varsitytutors.com.

Algebra Questions

Algebra Questions Algebra is the main branch of Mathematics which involves the relationship of numbers and the variables. There are different types of topics covered under Algebra. They are quadratic equations, linear equations in one or more variables, logarithmic and exponential functions, fractions etc. We use different types of formulas to solve the algebra questions. The algebra questions can be solved in an easy way by simply applying the formulas that are given to us. Following are some of the examples which are based on this concept. Example 1: John worked 22 hours this week and made $132. If he works 15 hours next week at the same pay rate. How much will he make? Solution: Number of hours John worked in First week = 22 hours Number of dollars made in first week = 132 dollars Pay rate = Money gained/ Working hours = 132/22 = 6 Dollars per hour Number of hours John worked in the next week = 15 hours The Amount of money made by John = (Number of working hours) times (Pay rate) = (15) times (6) = $90. Example 2: Alma wants to invest $4,000 at 6% simple interest rate for 5 years. How much interest will she receive? Solution: The amount = P = $4000 R = 6 % T = 5 years We have a formula to find the simple interest that is Simple interest = PRT/100 Now we can plug the values into this formula Simple interest = 4000 * 6 * 5/100 = $1200
