Useful Chemicals in Percentage Yield Chemistry Labs

Useful Chemicals in Percentage Yield Chemistry LabsPercentage yield chemistry labs are constructed to offer a range of laboratory equipment to students and professionals in the chemical sciences. Since grade level is more than commonly chosen, the facilities tend to focus on a one grade level. Chemical laboratories, however, can be used at any grade level. It all depends on your particular chemistry needs.Percentage yield chemistry laboratories are stocked with the latest equipment for graduate level programs and beyond. There are several different types of laboratory equipment you might need. Some of the most commonly used instruments include:An oxidation state oxygen absorption spectrometer will be able to detect sulfur compounds and their oxidation. Oxidation state detectors are particularly useful for detecting high concentrations of sulfur compounds. This instrument can be placed in a capillary tube where it can detect solid chemicals in the gas phase.A nitrogen gas analyzer wil l be used to detect inorganic compounds. Nitrogen analyzers are highly reliable tools for performing complex spectroscopic studies. These instruments are often combined with liquid chromatography, gas chromatography, and mass spectrometry systems.A flow cytometer is a lab grade, biocompatible needle-based instrument that measures cell volume. These devices are very precise measuring devices. They can be used in a variety of different situations, including in tissue culture experiments, tissue preservation, and as samples for DNA extraction and sequencing.A centrifugal force grader is used to measure the intensity of a chemical gradient. The centrifugal force grader is the most commonly used instrument in laboratory chemistry. The grader can be used to generate a highly selective flow of media in a medium reactor that works in conjunction with a large thermocouple for the concentration of specific analytes.TLC plates are used to measure the purity of any biological samples or tablets . These instruments are made from clear glass. They include a neutral compound, an activated carbon block, and an activated charcoal block. A TLC plate can be used to examine the purity of a sample, collect samples, and differentiate between substances of known or unknown composition.

Trigonometry Tutoring Helping Your Student Navigate Mid-Fall Challenges

Trigonometry Tutoring Helping Your Student Navigate Mid-Fall Challenges Trigonometry Tutoring: Helping Your Student Navigate Mid-Fall Challenges Mid-fall is a critical time of the school year for high school students: they experience homework overload, are faced with demanding group projects, and must prepare for numerous quizzes and exams. Teens involved in extra-curricular activities such as student government or sports may also dedicate a significant amount of time after school to these endeavors, further cutting into homework and study time. For junior and senior high school students, mid-fall can also bring with it the challenge of advanced coursework, which tends to accelerate as the year progresses. Trigonometry, is one such course that can prove problematic. Many students struggle to master the complex skills of this subject, such as inverse functions, trigonometric identities, polar equations, and graphing. As trigonometry is a building block in the field of mathematics and knowledge of the subject is often expected of incoming college freshmen, your students success in this course is about more than just a letter grade. The significance of trigonometry can also extend beyond college, as many career paths require mastery of this branch of mathematics. Fields demanding proficiency in trigonometry include architecture, navigation, engineering, digital imagery, astronomy, aircraft design, flight projection, and many more. In addition, an understanding of trigonometry is required before a student can take calculus, a mathematics course that is a pre-requisite for numerous college majors such as biology, environmental science, physics, marketing, and business administration, among others. With so many majors and careers requiring higher-level math skills, theres a good chance your students trigonometry course will directly affect his or her future. Furthermore, poor performance in a course like trigonometry can damage your teens confidence. Many high school students must work hard at trigonometry to be successful; dont let your student feel as though he or she is alone in this struggle. Lack of confidence in one subject can develop into to a lack of confidence in others, as well as deter a student from pursuing a mathematics-heavy career path. Trigonometry matters, so dont wait until your students report card is issued to determine if he or she needs help with this critical subject. Addressing any issues early in the school year affords you time to get help for your student and improve his or her understanding and grade. Speak to your student about class progress, help with homework assignments when possible, and reach out to his or her teacher for more insight. In addition, determine if your student needs help focusing by assessing the impact of his or her extra-curricular commitments and study habits. Recognizing whether your student needs help understanding the material or is simply stretched too thin and requires more study time will help you determine how to get your child back on track. The Huntington Learning Center offers effective one-to-one trigonometry tutoring to help your student tackle daily assignments, master necessary skills and concepts, prepare for quizzes, and improve his or her grades. For information on trigonometry tutoring and all of our services, contact The Huntington Learning Center at 1-800-CAN-LEARN, schedule a consultation online, or visit one of our centers.

5 Things Every Rising Senior Should Do This Summer

5 Things Every Rising Senior Should Do This Summer 5 Things Every Rising Senior Should Do This Summer College juniors are excited that the academic year is finally coming to an end.   In many ways, college is almost over but there is still a lot to do before graduation. Additionally, once college is officially over students will need to start looking for jobs and adjust to a professional lifestyle. There are some things students can do the summer between their junior and senior year to make the last year of college and the graduation process run smoothly. Unfortunately, students who dont keep track of graduation requirements and other relevant details may end up being a fifth-year senior at the last minute. Its better to stay on top of things and plan ahead to have a great final year as a full-time student. 1. Look through transcripts The first thing rising seniors should do is look through their transcript. Many students find out they are just one or two courses short of graduation, which can prevent them from getting their diploma the following spring. If a student made a miscalculation earlier on, theres still time to make it right before the start of senior year. One option is to take some elective courses over the summer to get extra units. Another option is to take a heavier load of courses starting in the fall. Most universities have a range of what is considered “full time.” It might be better to take five classes instead of four and still graduate on time. If students are at all confused about this process, they are encouraged to speak with one of the academic advisors who can look through everything and make sure the student is on the right track. 2. Arrange work experience Rising seniors are also encouraged to arrange some relevant work experience over the summer. This may consist of an internship or a paid position. Either way, its a good idea to have something productive listed on a resume the summer before graduation. Students who are overwhelmed with what they have already completed throughout the academic year and would rather just relax should know that many internships are only one or two weeks long but still add to a students resume. Its important to have real life on-the-job experience as well as something impressive to put on paper. 3. Volunteer Another great way to beef up that student resume over the summer is to volunteer. Sometimes, jobs within a professional field are simply unavailable to students who have not yet graduated. However, there is almost always a need for a volunteer. This is different from an internship in that students can set a more flexible schedule. For example, if an internship is from 8 to 5 Monday through Friday, thats when the intern works. Volunteers, however, can say that theyre available Thursdays and Fridays from 2 to 6 p.m., for example. This is a great option for students who need to attend summer classes or need to have a part-time job to make ends meet (READ: 5 Ways to Survive Spring Semester as a Senior). 4. Meet with professors and TAs Its a fabulous idea for students to meet with their professors or teaching assistants over the summer or as the term is wrapping up. This doesnt have to be a formal meeting in the professors office; it can be a simple meeting over a cup of coffee on campus. Professors and TAs can be a great resource when it comes to planning an entry-level career search or looking for an internship. Most of them have great connections and knowledge that other people simply dont possess. Also, meeting with professors gives students an opportunity to ask any additional questions. If nothing else this meeting will let the professor know the student is genuinely interested in their major field of study and will maintain a professional connection for the future (READ: 3 Warning Signs of Senioritis). 5. Arrange and informational interview Another great thing for rising seniors to do over the summer is arrange an informational interview with somebody in the field they plan to go into. This should not be confused with an official job interview. An informational interview is simply asking someone who is already a seasoned professional to provide some mentoring or advice. This gives students the opportunity to put questions without the pressure of having a full-time job on the line. Summer is the perfect time to catch-up and get ahead on your schooling.

A Guide to Speaking Up at Work When Youre Shy

A Guide to Speaking Up at Work When You're Shy Image via Pixabay.com Practice what you need to say beforehand This might seem like something you’d do to prepare for a public speaking class instead of a real-life situation. Don’t write this idea off as being silly just yet. Preparation is the key to success. It can be easy for shy people to get nervous once they’re face-to-face with another person. Your mind starts reeling, and you start panicking, and the next the thing you know … you’ve forgotten half of the things you wanted to tell this person, be it a coworker or your supervisor. That’s a problem. Nervously spewing half of your message isn’t why you wanted to talk to the person. You want to make sure that you state everything that needs to be said. That’s where practicing comes in. If you take the time to practice for a few minutes before you have to face the real situation, you will find it easier to recall everything that needed to be said. Sit in front of the mirror and practice what you want to say to this person (or group of people) for a couple of minutes to an hour. Make sure you cover everything! It might help you to remember if you write down a list of points you’d like to address. Read over them a couple of times, then practice without looking at your paper. Pretty soon, you’ll have it memorized. Just remember, when you get in front of the people you need to talk to, take a deep breath and do it just like you rehearsed. It will curb your anxiety knowing that you have what you want to say memorized. Remember your strengths If you’re a college student, you might find that you’re among the youngest of employees to work at your job. This may make you feel like you should listen to those who are older than you or that you have nothing to contribute. Get rid of those thoughts, pronto! You have so much to offer your job, including a fresh, new perspective. If you’re too scared to offer your perspective, you’re really doing a disservice to your company! Never doubt what you bring to the company. You have your own strengths and viewpoints that are valuable; don’t let yourself think otherwise! If you’re shy, your mind will try to keep your voice locked up. You’ve got to remind yourself of your strengths and let your voice be heard! See if you can talk to a supervisor one-on-one Do you get shy or nervous when you are made to speak in a large group of people? It might be easier for you to pull your supervisor aside and ask if you can speak to them alone, preferably in their office. At times, it’s just easier for shy people to focus when there is just one person that you need to voice your opinions to. Shyness can stop you from reaching your full potential in the workplace, if you’re not careful. Speaking up at work when you’re shy isn’t always easy but it is the right the thing to do. You’ll feel much better sharing your opinions rather than keeping them bottled up inside of you. Good luck!

Intermediate Students Choosing Between Physics, Chemistry and Biology

Intermediate Students Choosing Between Physics, Chemistry and BiologyAs a student, intermediate level students are not allowed to choose from the three subjects namely; physics, chemistry and biology. Since biology is a compulsory subject in high school, it is mandatory for every high school student to take it before leaving school. The subjects are highly respected in most of the colleges and universities.It is a system that is divided into the levels which are separated into two categories i.e. Physics, and Chemistry. The Physics course can be called the first tier. This is required for those students who had taken up science subjects in their high school and wish to pursue it further. It is a subject that can be taken by those students who wish to become an engineer or scientist.For some students, this course is not good enough and they wish to take up Biology, so that they may get the required knowledge to help them in their career. With this objective, there are many colleges an d universities that offer introductory biology courses.Another subject for intermediate students is Biology, and this course is obligatory for those students who had taken up physics and chemistry but not biology. Biology is required to ensure that an individual can take up well his career or other knowledge and skills required.While chemistry has been recommended by many medical professionals and doctors as the cure for a lot of diseases, it has a few limitations. These limitations are that it does not give any information about the earth sciences and its relationship with other subjects.While biology is required to become an engineer or scientist, physics is required to study natural sciences. It is a subject that is required to help the individual to complete his studies. It is compulsory to take up the physics course at the institute or college. For an advanced student, it is very necessary to know the details of all the subjects and study at a pace where he can handle all the w ork of the subject.An intermediate student has the option to take up the classes in the evening or during the weekend without any need of spending money on travel or accommodation. It is therefore essential to seek the permission of the college or university regarding the days and hours when the class can be taken.
