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. The hypothetical equation showing only the species that is oxidized or reduced in a redox reaction and the correct number of electrons transferred between the species in the complete - balanced equation.






2. Large molecular structures - strong covalent bonding - share qualities of IONIC And COVALENT






3. Side - to side parallel orbitals overlap to share electrons - the 2nd/3rd covalent bond between two atoms - cannot rotate and maintain the bond.






4. An element in an 'A' group in the periodic table; as a group these elements display a wide range of physical and chemical properties. In their atoms - the s and p sublevels in the highest occupied energy level are partially filled






5. The area of chemistry that is concerned with reaction rates and reaction mechanisms






6. 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






7. The maximum amount of product that can be produced from a given amount of reactant






8. Halogens; ns2np5 - - 2nd most reactive group - The Halogens; very active because of need to fill; form -1 ions; 7 electrons in valence shell; tend to form salts with elements from groups 1A and 2A






9. When a solute is dissolved in a solvent - it will dissociate until reaching an equilibrium point at which the rate of dissociation equals the rate of precipitation of the solute - regardless of any additional solute introduced into the mixture






10. PH=pka+log[base/acid] Used in titration based problems that relates the pH or pOH of a solution to the pK and the ratio of the dissociated species.






11. When polar molecules orient themselves such that the positive region of one molecule is close to the negative region of another molecule.






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






13. Small discrete increments of energy.






14. A subdivision of an energy level in an atom. They are divided into orbitals.






15. An ionic compound that resists changes in its pH






16. 5 different orbitals shaped like clover leaves and max electrons is 10






17. A physical property of a solution that depends on the number - but not the identity - of the disswolved solute particles; example properties include vapor pressure lowering - boiling point elevation - osmotic pressure - and frezzing point depression






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






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






20. The point during a titration when the number of H+ ions and OH- ions are equal. This is at the middle of the steepest part of the titration curve.






21. Simplest whole # ration of atoms in a compound






22. Keq describes the ratio of product concentration to reactant concentration - with each raised to the power corresponding ot its coefficient ion in the balanced equation






23. (chemistry) a substance that changes color to indicate the presence of some ion or substance






24. The pressure exerted by a vapor in equilibrium with its liquid or solid phase






25. Chalcogens - - Oxide O






26. Sum of all the masses - in AMU - present in one molecule of a molecular compound.






27. A measured amount of a solution of unknown concentration is added to a known volume of a second solution until the reaction between them is just complete






28. Property of the elements that can be predicted from the arrangement of the periodic table






29. The average distance between the nuclei of two bonded atoms






30. A reaction in which atoms of one element take the place of atoms of another element in a compound






31. The ratio of the number of moles of solute dissolved in one kilogram of solvent. molality (M = moles solute/kg of solution)






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






33. A solution in which water is the solvent






34. A covalent bond in which the bonding electrons are shared equally by the bonded atoms - resulting in a balanced distribution of electrical charge






35. Elements in the middle of the periodic table - in groups 3-12.






36. A base that can accept two moles of H+ per mole of itself (ex: SO4






37. At a constant pressure - the volume of an ideal gas is directly proportinal to its temperature: V (a) T

38. The amount of a substance that contains as many particles as there are atoms in exactly 12g of carbon -12






39. Nh/2p The angular momentum changes only in discete amounts with respect to the quantum number. Also E=- R_h/n^2






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






41. The molar amount of a solute that can dissolve in 1L of solvent until equilibrium - saturation - is reached






42. Defined acids as subtsances that produced H ions in water - while bases produced OH ions. When they reacted together - H and OH neutralise to make water






43. 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






44. A set of spectral lines that appear in the visible light region when a hydrogen atom undergoes a transition from energy levels n>2 to n=2.






45. Substance in which a solute is dissolved to form a solution






46. The process by which a gas escapes from one container to another at lower pressure through a tiny hole in the container.
