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.

3. Suspension of fine particles or droplets of one liquid in another - the two liquids being immiscible in each other; surrounded by an emulsifying agent






4. An ion that has a positive charge






5. Capacity to do work






6. The process of taking up by capillary - osmotic - chemical - or solvent action - as a sponge absorbs water






7. A chemical action in which both heat and light are given off






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






9. Having definite molecular or ionic structure






10. A terminal of an electrolytic cell






11. Top number on periodic table - The number of protons in the nucleus - The number of electrons in an atom






12. A substance used to remove the excess chlorine in the bleaching process






13. The smallest amount of fissionable material that will sustain a chain reaction






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






15. Temperature measured on the absolute scale - which has its origin at absolute zero






16. Separation of the ions of an ionic compound due to the action of a solvent






17. Forms of the same element that differ in their crystalline structures






18. The smallest particle of an element that retains the properties of that element and can enter into a chemical reaction






19. Rod of certain metal such as cadmium - which controls the speed of the chain reaction by absorbing neutrons in a nuclear reactor

39. A relatively weak force of attraction between polar molecules; a component of van der Waals forces






40. Covalence in which both electrons in a pair come from the same atom






41. The number of molecules in 1 gram-molecular volume of a substance - or the number of atoms in 1 gram-atomic mass of an element 6.02 x 10(-27)
