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






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






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






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






5. Capable of being drawn into a thing wire






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






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






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






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






10. E=mc2 - relates mass to energy






11. 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






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






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






14. A terminal of an electrolytic cell






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






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






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






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






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






20. A unit of heat; the amount of heat needed to raise the temperature of 1 gram of water 1 degree on the celcius scale






21. Chemical reaction that results in an absorption of heat






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






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






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






25. A property of a solution that depends primarily on the concentration - not the type of particles present






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






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






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






29. 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)






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






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






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






33. The process of taking up by capillary - osmotic - chemical - or solvent action - as a sponge absorbs water






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






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






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






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






38. Organic compound containing the -O- group






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






40. Referring to any substance that has basic properties






41. 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






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






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






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






45. Substance that takes water from another substance






46. An ion that has a positive charge






47. Unit of energy done by 1 dyne (1/980 g of force) acting through a distance of 1 cm; 2.4 x 10 (-11) kcal






48. Solid carbon dioxide






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






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