SAT Subject Test: Chemistry Vocab

Subjects : sat, science, 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.
1. A substance composed of two or more metals - which are intimately mixed; usually made by melting the metals together






2. A property of a solution that depends primarily on the concentration - not the type of particles present

21. Temperature scale that has 32 as freezing point and 212 as boiling point






22. Particles larger than those found in a solution but smaller than those in a suspension






23. Unit of energy done by 1 dyne (1/980 g of force) acting through a distance of 1 cm; 2.4 x 10 (-11) kcal






24. One of the "building blocks" of proteins; contains one or more NH2- groups that have replaced the same number of hydrogen atoms in an organic acid






25. Ethyl alcohol that has been poisoned in order to produce a cheaper alcohol for industrial purposes






26. Chemical reaction that results in the giving off of heat
