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






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






3. The mass per unit volume of a substance; mathematical formula D=m/V






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






5. A terminal of an electrolytic cell






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






7. The temperature above which no gas can be liquefied - regardless of the pressure applied






8. A reaction produced during nuclear fission when at least one neutron from each fission produces another fission - so that the process becomes self sustaining without additional external energy






9. A cell in which electrolysis is carried out






10. Organic compound formed by dehydrating oxidized alcohol; contains the characteristic - CHO group






11. A substance composed of two or more metals - which are intimately mixed; usually made by melting the metals together






12. Solid carbon dioxide






13. A water wolution that contains an excess of hydroxide ions; a proton acceptor; a base turns litmus paper blue and neutralizes acids to form salts






14. To take water from a substance






15. The process whereby gases or liquids intermingle freely of their own accord






16. Bonding accomplished through the sharing of electrons so that atoms can fill their outer shells






17. Nuclear reaction that releases energy because of the splitting of large nuclei into smaller ones

20. 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)






21. The use of radioactive carbon-14 to estimate the ages of ancient materials - such as archaeological or paleontological specimens






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






23. A substance that speeds up or slows down a reaction without being permanently changed itself






24. 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






25. A substance composed of elements chemically united in definite proportions by weight
