Sixty multiple-choice chemistry questions make up this comprehensive exam used for the 2001 US National Chemistry Olympiad. Every topic that you would expect to approach in a general chemistry class is queried on. You could easily use this as a first semester exam or as a practice for the final. An answer key is included, making it a cinch for you to use!
In this National Olympiad exam worksheet, chemistry apprentices answer sixty multiple choice questions including general chemistry topics such as atomic structure, gases, problem solving, writing and balancing equations and solutions. This and other National Olympiad exams are outstanding in content and format.
This 60-question comprehensive exam was designed to determine who would go on to compete in the 2000 US National Chemistry Olympiad. Hopefuls answer multiple choice questions regarding all chemistry topics taught in the first year general chemistry curriculum with a focus on laboratory experience. You can use this as a final exam for your chemistry class. An answer key is attached.
Here is a copy of a past national challenge exam that you can use in your general chemistry course as a unit or semester review. Sixty multiple-choice questions query learners on properties of matter, stoichiometry, reactions, and different intermolecular forces. The American Chemical Society Olympiad Examinations Task Force has produced this and other annual exams that are all-inclusive and professional in appearance. An answer key is included for your convenience. 
Sixty multiple choice questions cover the entire gamut of chemistry concepts. This is the local section of the U.S. National Chemistry Olympiad, where your chemistry candidates take a shot at entering the national competition. They answer questions about everything from properties of liquids and phase changes, to electrolysis products and molecular geometry. You could actually use this as a final exam for your class, a course review, or a practice for the actual chemistry challenge.
In this chemistry olympiad problem solving activity, chemistry pupils solve eight problems on a variety of topics including periodic trends, phase changes, ionization reactions, catalysts and titrations.
A variety of topics including reaction rates, combustion reactions, periodic trends, and ionization reactions are included in this exam. Test takers also practice calculating empirical and molecular formulas of compounds.
The National Chemistry Olympiad exams are comprehensive tests covering an entire  year of chemistry concepts. You can use them as practice for competing in the challenge, or simply as a review, or as an actual final exam for your general chemistry class. This particular part of the three-part exam consists of 60 multiple choice questions. Read through it before assigning to make sure every question is relevant to your curriculum. As a bonus, you will find an answer key attached.
Sixty multiple-choice questions test on a variety of first year chemistry subjects. In order to succeed, exam takers must be competent with properties of elements, stoichiometry problems, gas laws, bond dissociation, and types of reactions. A page is provided that displays a comprehensive chart of abbreviations and symbols, constants, and the periodic table. Also, an answer key is provided for teachers. This is a top-notch exam!
Only eight problems are on this competitive national chemistry exam. It required the balancing of chemical equations, solving stoichiometry questions, and more. This is part two of three of the national exam. Also available is a local pre-competition exam. All of these resources are well-written and neatly formatted tests that you can use in your general chemistry curriculum or as preparation practice for the National Chemistry Olympiad.
As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of chemistry curriculum. Topics include, but are not limited to pH, molecular geometry, bonding, behavior of gases and solutions, phase changes, and chemical reactions. Use this as a final exam or as a practice for those who want to enter the nation-wide challenge.
Using a sugar solution as an example Sal is able to describe the movement of water molecules from an area of a certain concentration to another.
Chemists consider a situation in which an ethanol producer needs to determine how much to add to t-butanol to prevent freezing during transport. They work in the laboratory to obtain the freezing point depression constant for the t-butanol. They graph the temperature changes and answer questions on the provided lab sheet. This is an outstanding application of freezing point concepts to a real-life scenario.
In this National Chemistry Olympiad test, junior chemists answer eight problem solving questions on a variety of topics. These include calculating molarity of solutions, determining rates of reactions, calculating decay and discussing topics such as electrolysis.
In this chemistry worksheet, students examine the given concept in order to apply in the laboratory setting. The sheet includes in depth background information.
In this chemistry exam learning exercise, students solve 11 problems including topics such as writing equations, solving for unknown values, calculating formulas, and finding the density and reaction rates of solutions.
For each of the eight solutions, there are are number of questions about their concentration, molarity, or solubility curve.
Students conduct an oxidation experiment in which they must determine how much hydrogen peroxide (H2O2) is actually in a store-bought solution of H2O2.
Learners predict changes in freezing and boiling points of water, given type and quantity of solute added. They solve word problems for changes to boiling points and freezing points of solutions based upon data supplied. They describe and discuss the evolution of glass making through the ages.
In this chemistry worksheet, learners examine the concept of solubility of silver chloride. The sheet has in depth concept and laboratory instructions.
