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






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






3. 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)

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






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






6. E=mc2 - relates mass to energy






7. Having definite molecular or ionic structure






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






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






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






11. 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






12. Organic compound containing the -O- group






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






14. 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






15. Science concerned with the compositions of substances and the changes that they undergo






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






17. The point in a reversible reaction at which the forward reaction is occurring at the same rate as the opposing reaction






18. The process of first vaporizing a liquid and then condensing the vapor back into a liquid - leaving behind the nonvolatile impurities






19. The process of separation of a solution by diffusion through a semipermeable membrance






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






21. 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






22. Referring to any substance that has basic properties






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






24. Usually - a strong base - such as Sodium hydroxide - potassium hydroxide






25. Heat content of a chemical system






26. Capable of being drawn into a thing wire






27. A cell in which electrolysis is carried out






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






29. A specially treated and finely divided form of carbon - which possesses a high degree of absorbtion






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






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






32. An organic salt formed by the reaction of an alcohol with an acid






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






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






35. Depositing a thin layer of metallic element on the surface of another metal by electrolysis






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






37. 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






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






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






40. 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)






41. The flow of a gas through a small aperture






42. Solid carbon dioxide






43. 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

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






49. High=speed - negatively charged electrons emitted in radiations






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