MCAT Chemistry

Subjects : mcat, science
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. Contains nonmetals - 7 valence electrons in it's outermost energy level. Very reactive






2. Any sample of a given compound will contain the same elements in the identical mass ratio.






3. The percent by mass of each element in a compound

5. (chemistry) the sum of the relative atomic masses of the constituent atoms of a molecule






6. Gram equivalent weight of solute per liter of solution - often denoted by N.






7. 1913 - Niels Bohr - said that electrons formed specific layers instead or random ones - said atoms atoms absorb and give off energy when the electrons move from one shell to another






8. The ratio of the actual yield to the theoretical yield for a chemical reaction expressed as a percentage; a measure of the efficiency of a reaction






9. The intermolecular force in which a hydrogen atom that is bonded to a highly electronegative atom is attracted to an unshared pair of electrons of an electronegative atom in a nearby molecule

13. The energy required to break a chemical bond and form neutral isolated atoms






14. The process of decomposing a chemical compound by the passage of an electric current.

16. 5 valence electrons -3 ions - Nitride N






17. Specifies the specific orbital in which the electron is most likely to be found. - Third quantum number - designated as ml. Describes a particular orbital within a subshell where an electron is very likely to be found. Possible values are integers in






18. Play- by- play showing the individual steps of a reaction - including the formation and destruction of any reaction intermediates that may occur.






19. The ways in which electrons are arranged in various orbitals around the nuclei of atoms






20. Sol - a chemical process in which solvent molecules and molecules or ions of the solute combine to form a compound






21. A model of acids and bases which an acid is hydrogen ion donor and base is a hydrogen ion acceptor.






22. A reaction where a compound does Not change its molecular structure.






23. A fundamental constant - h - that relates the energy of light quanta to their frequency: h = 6.6 X 10^-34 joule

26. An atom or group of atoms that has a positive or negative charge






27. An equilibrium expression used to measure weak - acid strength - given by the ratio of the product of the products' molar concentrations to the product of the reactants' molar concentrations - with each term raised to the power of its stoichiometric






28. The formation of one or more covalent bonds between an electron pair donor and an electron pair acceptor






29. PH of a molecule at which it contains no net electric charge - isoelectric point.






30. A chemical reaction involving the transfer of one or more electrons from one reactant to another; also called oxidation - reduction reaction.






31. The solubility of a gas in a liquid is directly proportional to the partial pressure of that gas on the surface of the liquid

36. The reaction of the ions that characterize acids and the ions that characterize bases to form water molecules and a salt






37. A reaction in which two or more substances combine to form a single substance A+B>>>>>>>C






38. Resulting positive nuclear charge an outer electron senses after accounting for the shielding effect of inner core electrons. Abbreviated as Z(eff). Increases from left to right - and bottom to top on the Periodic Table.






39. (physics) the smallest discrete quantity of some physical property that a system can possess (according to quantum theory) E=hf
