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






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






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






4. 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






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






6. A substance that speeds up or slows down a reaction without being permanently changed itself






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






8. The process whereby gases or liquids intermingle freely of their own accord






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






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






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






12. 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






13. 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






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






15. High=speed - negatively charged electrons emitted in radiations






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






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






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






19. Process for converting atmospheric nitrogen into compounds






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






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






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






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






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






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






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






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






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






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






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






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






32. A liquid that will conduct and electric current






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






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






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






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






37. A compound such as CH3NH2 - derived from ammonia by substituting one or more hydro-carbon radicals for hydrogen atoms






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






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






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






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






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






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






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






45. Having no definite crystalline structure






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






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






48. 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






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






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