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. Capable of being drawn into a thing wire






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






3. 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






4. A terminal of an electrolytic cell






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






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






7. To take water from a substance






8. Heat content of a chemical system






9. A reaction in which two chemical substances exchange ions with the formation of two new compounds






10. Containing no water






11. The process by which suspended matter is removed from a liquid by passing the liquid through a porous material






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






13. The difference in potential between an electrode and the solution in which it is immpesed






14. An instrument - invented by Toricelli in 1643 - used for measuring atmospheric pressure






15. The flow of a gas through a small aperture






16. Loss by a substance of its water of hydration on exposure to air at ordinary temperatures






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






18. 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






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






20. A substituent obtained from a saturated hydrocarbon by removing one hydrogen atom -Examples: methyl(CH3) ethyl(C2H5)






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






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






23. 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






24. Referring to a compound composed of two elements such as water






25. Negatively charged particle - Mass is 9.109x10(-28)






26. Having no definite crystalline structure






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






28. 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






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






30. Referring to a hydroxide that may have either acidic or basic properties - depending on the substance with which it reacts






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






32. Shows only the simplest ratio of the number and kids of atoms






33. E=mc2 - relates mass to energy






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






35. The process of forming definitely shaped crystals when water is evaporated from a solution of the substance






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






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






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






39. A chance that alters the atomic structures of the substances involved and results in different properties






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






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






42. 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






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






44. 1/2 the distance between adjacent nuclei in the crystalline or solid phase of an element; distance from the atomic nucleus to the valence electrons






45. 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)
