  4. solubility rule 2:
  5. on the right is the:
  1. a 1)metal oxides + h2o form metal oh.
    2) nonmetal oxides + h2o form oxy-acids.
    3) alkali metals react readily with halogens to form salts.
    4) many metals react readily with oxyen to form metal oxides.
  2. b except for those in rule 1, carbonates, hydroxides, oxides, sulfides, and phosphates are insoluble.
  3. c they have to do with the electromotive series. it arranges most reacted to least reacted.
  4. d nitrates and acetates are soluble.
  5. e products

5 Multiple choice questions

  1. the reactions does occur
  2. a+b=ab
  3. they form a 7 on the periodic table: H, N, F,Cl,O,Br,I. all have a 2 at the end
  4. metals replace metals visversa! metals can replace hydrogen.
  5. hydrocarbon + o2= co2 + h2o

5 True/False questions

  1. one soluble and one insoluble:have a reaction


  2. if the yield sign has elec:this means electricity is used!


  3. single replacement:a+bc= b+ac


  4. Decomposition:ab=a+b


  5. if it has H2SO4:a+b=ab
