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






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






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






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






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






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






8. 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)






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






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






11. Graduated glass tube into which gases are placed and subjected to an electric spark; measures the individual volumes of combining gases






12. Substance that takes water from another substance






13. Having no definite crystalline structure






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






15. Organic compound containing the -O- group






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






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






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






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






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






21. The measure of disorder in a system






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






23. Separation of the ions of an ionic compound due to the action of a solvent






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






25. Process for converting atmospheric nitrogen into compounds






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






27. 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






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






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






30. 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






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






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






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






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






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






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






37. An ion that has a positive charge






38. Heat content of a chemical system






39. Forms of the same element that differ in their crystalline structures






40. Containing no water






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






42. 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






43. A terminal of an electrolytic cell






44. 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)

46. The highest temperature at which water vapor condenses out of the air






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






48. E=mc2 - relates mass to energy






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