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. Heat content of a chemical system






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






3. Process of heating an organic substance - such as coal - in the absence of air to break it down into solid and volatile products






4. 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






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






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






7. Solid carbon dioxide






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






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






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






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






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






13. Containing no water






14. 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)






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






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






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






18. Chemical reaction that results in an absorption of heat






19. 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






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






21. Colloidal substance that forms a film about the particles of two immiscible liquids so that one remains suspended in the other






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






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






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






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






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






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






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






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






30. A substance composed of two or more metals - which are intimately mixed; usually made by melting the metals together






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






32. 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

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

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






42. The measure of disorder in a system






43. 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






44. 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
