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. Having no definite crystalline structure






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






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






4. Referring to any substance that has basic properties






5. The process of separating the ions in a compound by means of electrically charged poles






6. Solid carbon dioxide






7. To take water from a substance






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






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






10. The rapid escape of excess gas that has been dissolved into a liquid






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






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






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






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






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






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






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






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






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






20. A cell in which electrolysis is carried out






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

29. Capable of being drawn into a thing wire






30. Isotope of hydrogen - sometimes called heavy hydrogen - with an atomic weight of 2






31. 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






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






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






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






35. 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






36. Substance that takes water from another substance






37. A terminal of an electrolytic cell






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






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






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






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






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






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






44. One of the "building blocks" of proteins; contains one or more NH2- groups that have replaced the same number of hydrogen atoms in an organic acid






45. 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)
