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.

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






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






8. The average mass of a number; bottom number on the element






9. An organic hydroxyl compound formed by relacing one or more hydrogen atoms of a hydrocarbon with equal number of hydroxyl (OH) groups






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






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






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






13. Unit for expressing the kinetic energy of subatomic particles; the energy acquired by an electron when it is accelerated by a potential difference of 1 volt






14. Nuclear reactor in which more fissionable material is produced than is used up during operation






15. Continuous zigzagging movement of colloidal particles in a dispersing medium - as viewed through and ultramicroscope






16. Absorbtion by a substance of water from the air - so that the substance becomes wet






17. The energy needed to break a chemical bond and form a neutral atom






18. A water solution that has an excess of hydrogen ions; an acid turns litmus paper pink or red - has a sour taste - and neutralizes bases to form salts






19. The rapid escape of excess gas that has been dissolved into a liquid






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






21. Having no definite crystalline structure






22. In metallurgy: a substance that helps to melt and remove the solid impurities as slag

31. An ion or particle that has a negative charge and thus is attracted to a positively charged anode






32. Chemical reaction between an alcohol and an acid - in which an ester is formed






33. Residual radioactivity from an atmospheric nuclear test - eventually settles on the surface of the earth






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






35. An instrument used to measure the amount of heat liberated or absorbed during a change






36. A compound derived from another compound by the removal of water; it will combine with water to form an acid (acidic anhydride) or base (basic anhydride)
