  1. decomposition reactions:
  2. single replacement rxns with nonmetals:
  3. Double replacement reactions:
  4. Single replacement rxns:
  5. one soluble and one insoluble:
  1. a 1) some metallic hydroxides when heated decompose to form a metal oxide + h20
    2) some oxy-acids when heated decompose to form a metal oxide + h20
    3) some metallic carbonates when heated decompose to form a metal oxide + carbon dioxide
    4) some metallic chlorates when heated decompose to form a metal chloride + oxygen gas
    5) most metallic osides are stable but few decompose when heated to form a metal + o gas
    6) some compounds can be decomposed by electricity into their elements.
  2. b they have to do with the electromotive series. it arranges most reacted to least reacted.
  3. c will occur only if: both products are soluble, and it is a reaction between a acid and a base! memorize solubility rules!
  4. d only use the periodic table, no electromotive series! a nonmetal can replace a nonmetal below itself on the periodic table!
    f, o, cl, br, i
  5. e have a reaction

5 Multiple choice questions

  1. this means electricity is used!
  2. have no reaction
  3. except for those in rule 1, carbonates, hydroxides, oxides, sulfides, and phosphates are insoluble.
  4. matter is neither created nor destroyed!
  5. binary compounds of group 17 other than F with metals are soluble except those of silver, mercury I, and lead

5 True/False questions

  1. solubility rule 2:except for those in rule 1, carbonates, hydroxides, oxides, sulfides, and phosphates are insoluble.

          

  2. Diatomic elements:a+bc= b+ac

          

  3. on the left is the:products

          

  4. solubility rule 4:all sulfates are soluble except those of barium, strontium, lead, calcium, silver, and mercury I.

          

  5. both insoluble:a+b=ab
