The mole is a standard SI unit used primarily by chemistry. This is a collection of test questions dealing with the mole. These test questions deal with calculating and using molar masses. These questions deal with calculating mass percent and finding empirical and molecular formulas. When answering the questions, remember that the molecular mass of a molecule is the total mass of all the atoms making up the molecule. This practice test deals with finding empirical formulas of chemical compounds.
Keep in mind that the empirical formula of a compound is a formula that shows the ratio of elements present in the compound but not the actual numbers of atoms found in the molecule. This practice test deals with finding the molecular formula of chemical compounds. Note that the molecular mass or molecular weight is the total mass of a compound. These ratios can also be used to determine which reactant will be the first reactant to be consumed by the reaction. This reactant is known as the limiting reagent. This collection of 10 test questions deals with calculating theoretical yields and determining the limiting reagent of chemical reactions.
Each Exercise focuses on a single concept or skill. You should complete Exercises immediately after the concept or skill is discussed in class to ensure that you fully understand it so that you do not fall behind. It is intended that a single exercise should take no more than fifteen minutes to complete by a student who understands the material and some can be done in significantly less time than that. As such, they can be done in breaks between classes or similar short breaks in your day.
Practice Test Questions are longer sets of practice questions, the majority of which have been taken from tests given at the University of Lethbridge in the last twelve years. The questions within a set of Practice Test Questions are in no particular order, just as questions on an actual test would be in no particular order. Unless your instructor says otherwise, all material on all Exercises and Practice Test Question sets is testable.
Be aware that reading the answer key to any Exercise or Practice Test Question before completing it is counterproductive and robs you of a learning opportunity. If you get stuck, ask your instructor or another student for help. Your brain does not make the same connections when you read an answer as it does when you figure it out yourself.

Unlike biology, Earth and space sciences, and environmental sciences, chemistry is governed by strict mathematical constructs and principles. High School Chemistry allows students an opportunity to apply mathematical and reasoning skills outside of math classes, developing an understanding for chemical systems and reactions on a molecular level. Whether you need top Chemistry tutors in Syracuse , Chemistry tutors in Chicago , or top Chemistry tutors in San Francisco , working with a pro may take your studies to the next level.
Most High School Chemistry classes begin with an introduction to elements and compounds, with a focus on atoms and molecules, respectively. Students gain familiarity with elemental properties, groupings, and the periodic table. Solution chemistry is also introduced early in the course, focusing on solubility rules and precipitate formation. Electron configuration is used to introduce Lewis dot structures and bonding principles, with a focus on the differences between ionic and covalent bond formation and the development of intermolecular forces.
These topics will all be covered before reaction chemistry, which will build a strong fundamental foundation. Varsity Tutors offers resources like free High School Chemistry Diagnostic Tests to help with your self-paced study, or you may want to consider a Chemistry tutor. Introductions to reaction chemistry will focus on the four principle reaction types: addition synthesis reactions, dissociation decomposition reactions, single-replacement reactions, and double-replacement reactions. Some courses will classify specific reactions such as oxidation-reduction, acid-base, or combustion as their own categories. Balancing chemical equations and understanding stoichiometry become essential components to the course. Students will frequently be asked to make several stoichiometric conversions to arrive at an answer.
Manipulating given quantities is an essential skill in High School Chemistry, and will be tested through questions about limiting reagents, precipitate formation, and other conversion questions. High School Chemistry has a heavy foundation in math, and may require formula memorization. Most formulas will revolve around the properties of gases, chemical equilibrium, and pH, though different courses may introduce different formulas. It will be important to know the gas laws and relationships regarding the equilibrium constant of a reaction; pH and acidity are commonly tested in High School Chemistry, and you will need to be familiar with exponents and logarithms in order to solve these types of questions. Some High School Chemistry courses will include a laboratory component, which will emphasize the scientific method, hypothesis formation, and chemical procedures.
Students should be prepared to analyze solution chemistry, acids and bases, and stoichiometric principles in a hands-on environment. Titrations often play a large role in the laboratory portion of High School Chemistry. After taking a course in High School Chemistry, students will have a solid understanding of several relationships between observable phenomena and the mathematics governing those phenomena. This will serve as a tool for understanding physical chemistry and relationships in any physics or chemistry endeavors that students face in the future.
Each free Practice Test consists of about a dozen problems that you might be presented with in a High School Chemistry course. You can choose to focus on doing questions by individual topic or in more comprehensive groupings. After completing a High School Chemistry Practice Test, you can see data about how long you took to answer each question, how you did in relation to other test-takers, and detailed explanations for every question you were asked.
Take one of our many High School Chemistry practice tests for a run-through of commonly asked questions. You will receive incredibly detailed scoring results at the end of your High School Chemistry practice test to help you identify your strengths and weaknesses.

Exams The exam format typically consists of conceptual questions and problems to be worked and answered multiple choice format. Red ParScore Scantron sheets will be provided and used on the exam. See the syllabus for dates of exams. A common question is "How do I prepare for the exam? There isn't a single answer and it varies from student to student. General suggestions are given below. Read before lecture. Read the pertinent sections of the chapter before lecture, and work the sample exercises. Test yourself by attempting the Give It Some Thought questions. Take notes during lecture. Taking well-organized notes helps you understand the material.
Taking notes by hand is likely to help develop a deeper understanding of the material and better long-term comprehension. Cramming won't work. Cramming puts things into your short term memory and if you're exhausted, it's very short term. You should study throughout the weeks before the exam, so that when the day to take the exam comes, you will feel confident of your preparation. Learn the concepts via well-organized notes taken during lecture and reading the chapter. Make an outline of the materials you have been studying the chapter, without having the book open. How close does your chapter outline compare to the chapter summary and key terms, key skills, and key equations at the end of each chapter? Ensure you have the big picture and focus on meeting the chapter objectives.
You can listen and watch someone tell you how to hit a baseball, run a marathon, or learn a second language, but without practice none are possible. Complete the MasteringChemistry exam review assignment. Work problems and answer questions, preferably new problems from the end of the chapter. Start with ones in the middle of the section, then towards the middle-end of the section if you correctly answer it. Manage Time and Get Help. Don't get stuck for too long on one problem or concept. Read the textbook, lecture notes, and try simple problems and questions first.
