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. High=speed - negatively charged electrons emitted in radiations






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






3. A liquid that will conduct and electric current






4. A cell in which electrolysis is carried out






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






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






7. Negatively charged particle - Mass is 9.109x10(-28)






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






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






10. 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






11. Capable of being drawn into a thing wire






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






13. An ion that has a positive charge






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






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






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






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

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






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






22. 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






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






24. Positively charged helium nuclei






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






26. A terminal of an electrolytic cell

28. A relatively weak force of attraction between polar molecules; a component of van der Waals forces






29. Substance that takes water from another substance






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






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






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






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






34. 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






35. A reaction in which two chemical substances exchange ions with the formation of two new compounds






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






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






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






39. Chemical reaction that results in an absorption of heat






40. 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
