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. One of the building blacks matter is composed of - only one type of atom; cannot be further decomposed






2. The measure of disorder in a system






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






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






5. A salt formed by replacing part of the hydrogen ions of a dibasic or tribasic acid with metallic ions - Examples: NaHSO4 - NaH2PO4






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






7. 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






8. Having definite molecular or ionic structure






9. A. change from gas to liquid B. the combination of molecules without water






10. A compound whose basic structure contains the benzene ring; it usually has an odor






11. Chemical reaction that results in an absorption of heat






12. Determines how a substance will behave in a chemical reaction






13. A change by which an element takes the place of another element in a compound






14. The process of separating the ions in a compound by means of electrically charged poles






15. An ion that has a positive charge






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






17. The temperature at which the vapor pressure of a liquid equals the atmospheric pressure






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






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






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






21. The union of atoms to form compounds or molecules by filling their outer shells of electonrs. This can be done through giving and taking electrons (ionic) or by sharing electrons






22. Capable of being drawn into a thing wire






23. Breaking down of a compound into simpler substances or constituent elements

26. The adhesion (in an extremely thing layer) of the molecules of gases - of dissolved substances - or of liquieds to the surfaces of solid or liquid bodies with which they come into contact






27. 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

29. Organic compound containing the -O- group






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

32. A nonmetallic oxide that - when placed in water - reacts to form an an acid solution






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






34. The breaking down of a compound into two or more simpler substances






35. Isotope of hydrogen - sometimes called heavy hydrogen - with an atomic weight of 2

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






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






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






41. Substance that takes water from another substance






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