5 Multiple Choice Questions

  1. a+bc= b+ac
  2. 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.
  3. a element can replace any element in a compound if the element in the compound is below it on the electromotive series.
  4. ab=a+b
  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

5 True/False Questions

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

          

  2. Single replacement rxns:they have to do with the electromotive series. it arranges most reacted to least reacted.

          

  3. on the left is the:products

          

  4. two soluble reactions:hydrocarbon + o2= co2 + h2o

          

  5. law of conservation of mass:matter is neither created nor destroyed!
