Sample question, from my chemistry quiz today:

    Which of the following pairs of ionic compounds do NOT have the same number of atoms in their chemical formulas?
  1. calcium bicarbonate and sodium dichromate
  2. aluminum cyanide and sodium sulfate
  3. barium permanganate and strontium nitrate
  4. ammonium chloride and aluminum phosphate

Hypothesis: Need to study more. Much more.
