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






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






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






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






5. 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






6. To take water from a substance






7. 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






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






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






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






11. The measure of disorder in a system






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






13. Referring to a hydroxide that may have either acidic or basic properties - depending on the substance with which it reacts






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






15. 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






16. 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






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






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






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






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






21. 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)






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






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






24. Process for converting atmospheric nitrogen into compounds






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






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






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






28. A liquid that will conduct and electric current






29. An instrument used to measure the amount of heat liberated or absorbed during a change






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






31. Organic compound formed by dehydrating oxidized alcohol; contains the characteristic - CHO group






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






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






34. 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






35. Shorthand method of showing the changes that take place in a chemical reaction






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






37. Solid carbon dioxide






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






39. 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






40. The flow of a gas through a small aperture






41. The series of radioactive elements starting with actinium - No. 89 - and ending with lawrencium - No. 103






42. 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)
