The Chemistry 6-12 subject examination consists of about 100 multiple-choice questions. A reference sheet and a scientific calculator will be provided. (Note: You may not bring your own calculator.) Question formats will include direct questions, sentence completion, graphics, command, and scenario. Each question will contain four response options, which will be answered by bubbling in choice A, B, C, or D.
The test encompasses 8 core competencies, each with between 5 and 22 skill areas. Competencies are defined as areas of content knowledge, with skills being the behaviors that demonstrate those competencies. Each competency is also assigned a percentage representing the approximate proportion of test items in that content area on the test. Together, the competencies and skills are representative of knowledge that has been determined by content specialists to be important for beginning teachers.
Test-takers will need to demonstrate knowledge of the nature of matter; energy and its interaction with matter; bonding and molecular structure; chemical reactions and stoichiometry; atomic theory and structure; the nature of science; measurement; and appropriate laboratory use and procedures.

C. 0.001 kilograms, 1,000 milligrams, and 100 centigrams
D. 0.001 kilograms, 10,000 milligrams, and 100 centigrams
2. An absolute zero temperature scale is known as a:
A. kelvin scale
B. Fahrenheit scale
C. Celsius scale
D. digital scale
3. What is the melting point of ice in the three temperature scales of Fahrenheit, Celsius, and kelvin?
A. 32 °F, 10 °C, and 27.3 K
B. 32 °F, 0 °C, and 273.15 K
C. 32 °F, .10 °C, and 253.25 K
D. 32 °F, .01 °C, and 233.35 K
4. Which is NOT an example of an oxidation-reduction reaction?
A. tarnishing silver
B. food metabolism
C. burning charcoal
D. boiling water
5. Stoichiometry is used to:
A. calculate the distance between two bonded nuclei
B. arrange elements in the order of how much they tend to react with water and acids
C. calculate the quantities of reactants and products in a chemical reaction
D. determine level of adsorption
1. C. A kilogram is equal to 1,000 grams; a milligram is equal to one thousandth of a gram; and a centigram is equal to one hundredth of a gram.
2. A. The kelvin temperature scale is an extension of the Celsius scale down to absolute zero, a hypothetical temperature characterized by an absolute absence of heat energy. Temperatures on this scale are called kelvins.
3. B. Temperature conversions to remember are that kelvin = degree Celsius + 273.15 and that degree Fahrenheit = degree C x 1.8 + 32.
4. D. A key to identifying oxidation-reduction reactions is recognizing when a chemical reaction leads to a change in the oxidation number of one or more atoms.
5. C. In its very simplest explanation, stoichiometry is the math behind chemistry.
