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. 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






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






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






4. 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)






5. 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






6. 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






7. An organic hydroxyl compound formed by relacing one or more hydrogen atoms of a hydrocarbon with equal number of hydroxyl (OH) groups






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






9. The minimum energy necessary to start a reaction






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






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






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






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






14. Substance that takes water from another substance






15. An ion that has a positive charge






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






17. Continuous zigzagging movement of colloidal particles in a dispersing medium - as viewed through and ultramicroscope






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






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






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






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






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






23. The process of separating the ions in a compound by means of electrically charged poles






24. 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)


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






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






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






28. A terminal of an electrolytic cell






29. Solid carbon dioxide






30. Having no definite crystalline structure






31. 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






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






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






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






35. A. change from gas to liquid B. the combination of molecules without water






36. An ion or particle that has a negative charge and thus is attracted to a positively charged anode






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






38. Nuclear reaction that releases energy because of the splitting of large nuclei into smaller ones






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






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






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






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