Test your basic knowledge |

AP Chemistry

Subjects : science, ap, chemistry
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

2. All _________ compounds are electrolytes






3. Kinetic Energy per molecule






4. If a change is imposed on a system at equilibrium - the position of the equilibrium will shift in a direction that tends to reduce that change
