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. High=speed - negatively charged electrons emitted in radiations






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






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






4. Streams of electrons given off by the cathode of a vacuum tube






5. 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






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






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






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






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






10. To take water from a substance






11. Chemical reaction that results in the giving off of heat






12. A temperature scale divided into 100 equal divisions and based on water freezing at 0 degress and boiling at 100 degrees






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






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






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






16. 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






17. A device used to accelerate charged particles to high energies for bombarding the nuclei of atoms






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






19. Solid carbon dioxide






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






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






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






23. Positively charged helium nuclei






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






25. A bond between atoms involving two electron pairs - unsaturated






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






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






28. 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






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






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






31. 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






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






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






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






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






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






37. Referring to any substance that has basic properties






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






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






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






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






42. 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






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






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






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






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






47. An organic hydroxyl compound formed by relacing one or more hydrogen atoms of a hydrocarbon with equal number of hydroxyl (OH) groups
