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






2. 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






3. 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)






4. 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






5. The measure of disorder in a system






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






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






8. Referring to any substance that has basic properties






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






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






11. Positively charged helium nuclei






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






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






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






15. An ion that has a positive charge






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






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






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






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






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






21. 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






22. A terminal of an electrolytic cell






23. 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






24. The minimum energy necessary to start a reaction






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






26. Substance that takes water from another substance






27. 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






28. Organic compound containing the -O- group






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






30. Residual radioactivity from an atmospheric nuclear test - eventually settles on the surface of the earth






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






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






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






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






35. Process for converting atmospheric nitrogen into compounds






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






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






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






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






40. A substance composed of elements chemically united in definite proportions by weight






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






42. The layer of gasses surrounding the earth - A unit of pressure (1 atm = 760mm of Hg or torr)






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






44. Unit for expressing the kinetic energy of subatomic particles; the energy acquired by an electron when it is accelerated by a potential difference of 1 volt






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






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






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






48. The temperature above which no gas can be liquefied - regardless of the pressure applied






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






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