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






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






3. 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






4. The energy needed to break a chemical bond and form a neutral atom






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






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






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






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






9. Solid carbon dioxide






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






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






12. Referring to any substance that has basic properties






13. The flow of a gas through a small aperture






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






15. Having definite molecular or ionic structure






16. A terminal of an electrolytic cell






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






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






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






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






21. Heat content of a chemical system






22. Capable of being drawn into a thing wire






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






24. Chemical reaction that results in an absorption of heat






25. A change by which an element takes the place of another element in a compound






26. The adhesion (in an extremely thing layer) of the molecules of gases - of dissolved substances - or of liquieds to the surfaces of solid or liquid bodies with which they come into contact






27. Particles larger than those found in a solution but smaller than those in a suspension






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






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






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






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






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






33. Substance that takes water from another substance






34. 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)






35. E=mc2 - relates mass to energy






36. The measure of disorder in a system






37. 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






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






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






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






41. The smallest particle of an element that retains the properties of that element and can enter into a chemical reaction






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






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






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






45. Containing no water






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






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






48. A cell in which electrolysis is carried out






49. Temperature scale that has 32 as freezing point and 212 as boiling point






50. 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
