  5. both insoluble:
  1. a the reactions does occur
  2. b a element can replace any element in a compound if the element in the compound is below it on the electromotive series.
  3. c matter is neither created nor destroyed!
  4. d this means the reaction is heated!

5 Multiple Choice Questions

  1. ab+cd=cb+ad
  2. a+b=ab
  3. will occur only if: both products are soluble, and it is a reaction between a acid and a base! memorize solubility rules!
  4. 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.
  5. 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
