Show Answers:

  1. What's an ionic bond?
    A bond where on atom loses electrons and the other one gains them
  2. What's a covalent bond?
    A bond where two atoms share electrons
  3. Cation
    Atom losing electrons. In ionic compound names, the cation comes first
  4. Anion
    Atom gaining electrons. In ionic compound names, it's the second part of the name, plus add "ide" at the end.
  5. Polyatomic anions
    Function like regular anions when creating ionic compounds. Example: Nitrate (NO3-)
  6. Nitrate
  7. Carbonate

    has four carbons
  28. Isomers
    Same elements, different structures.
  29. Methanol
  30. -ane
    has a single bond
  31. -ene
    has a double bond
  32. -yne
    has a triple bond
  33. -adiene
    has two double bonds
  34. -triene
    has three double bonds
  35. 1-butene
    CH2 = CH - CH2 - CH3
  36. 2-pentene
    CH3 - CH = CH - CH2 - CH3
  37. Ethyne
    H - C ☰ C - H
  38. 1,3-butadiene
    CH2 = CH - CH = CH2
  39. iso-
    means one of the carbons is not in line
  40. Acids
    Ionic compounds with hydrogen in front are acids. 

    Ex. HCl, H2S, H2SO4
  41. Acid + Base reaction?
    H20 plus a salt (ionic substance)
  42. pH
    • Acidity in a solution (or how much H+ is in it)
    • ex.
    • 0.1 M HCl 
    • 1x10-1 ↤take the exponent & change the sign:

  43. Alcohol
    Organic compound where an OH has a single bond to a C
  44. Ethanol
  45. Methanol (wood alcohol)
  46. Ethers
    Oxygen atom connected to two alkyls
  47. Dimethyl ether
    CH3 - O - CH3
  48. Methyl ethyl ether
    CH3 - O - CH2 - CH3
  49. Soluble compounds contain:
    • nitrates
    • acetates
    • ammonium (as cation)
    • Group 1 metals
    • Chlorides (not Ag+, Hg+, Pb2+, Hg2+)
    • Bromides (not Ag+, Hg+, Pb2+, Hg2+)
    • Iodides(not Ag+, Hg+, Pb2+, Hg2+)
    • Sulfates (Not Ba2+, Ca2+, Sr2+,Pb2+,Ag2+)
  50. Insoluble compounds contain:
    • Carbonates (except Group 1 metals or ammonium)
    • Phosphates (except Group 1 metals or ammonium)

  51. cyclo -
    Means atoms are arranged in a ring
  52. Nitrogen dioxide
  53. Dinitrogen tetroxide
  54. Molarity (M)
    Ex: Molarity of 5g LiCl?

    Li: 7g; Cl: 35.5g. 7+35.5 = 42.5g (one mole of LiCl)

    • 5g LiCl =    1M LiCl    = 0.12 M
    •                42.5 g LiCl
  55. % by volume
    [(volume of solute)/(volume of solution)] x 100%

    • Ex.
    • 5mL ethanol + 20mL H2O = 25mL
    • or 20% by volume solution
  56. Precipitation
    When mixing two soluble salts and we get an insoluble product
  57. Bases
    Ionic compounds with an OH

    Ex. NaOH, NH4OH, KOH
  58. Conjugate base
    After an acid dissociates, if one of the products can still have a proton added to it (so its charge is -), that's the acid's conjugate base.
  59. Acids have a pH of _________ than 7.
  60. Bases have a pH of _________ than 7.
  61. Buffer
    A mixture of an acid and its conjugate base, used to stabilize pH. 

    The base always has a cation (so it's mixed with something else).
  62. COOH
    Organic acid functional group.

    Ex. CH3COOH
  63. Ester
    Carbon bonded to one oxygen by a double bond and a second oxygen by a single bond; the second oxygen is also bonded to something not hydrogen.

    •           O
    •           ||

    •          O 
    •          ||
