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






2. 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)






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






4. 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






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






6. A unit of heat; the amount of heat needed to raise the temperature of 1 gram of water 1 degree on the celcius scale






7. An ion that has a positive charge






8. Substance that - when added to a solution - makes changing the pH of the solution more difficule






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






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






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






12. A cell in which electrolysis is carried out






13. A metallic oxide that forms a base when placed in water






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






15. The smallest amount of fissionable material that will sustain a chain reaction






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






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






18. The layer of gasses surrounding the earth - A unit of pressure (1 atm = 760mm of Hg or torr)






19. The numerical expression of the relative strength with which the atoms of an element attract valence electrons to themselves; the higher the number - the greater the attraction






20. A compound such as CH3NH2 - derived from ammonia by substituting one or more hydro-carbon radicals for hydrogen atoms






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






22. The electrode in an electrolytic cell that is negatively charged and attracts positive ions






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






24. 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






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






26. The series of radioactive elements starting with actinium - No. 89 - and ending with lawrencium - No. 103






27. A substance used to remove the excess chlorine in the bleaching process






28. Capable of being drawn into a thing wire






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






30. A relatively weak force of attraction between polar molecules; a component of van der Waals forces






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






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






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

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






36. A terminal of an electrolytic cell






37. Having definite molecular or ionic structure






38. 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






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

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






42. A liquid that will conduct and electric current
