Write the formula for each of the following compounds.
(a) Ammonium chromate
(b) Barium perchlorate
(c) Sodium hydrogen sulfate

Strategy

The polyatomic ions are treated as a single group with the formulas and charges listed in Table 2.2. Subscripts of the anions and cations are adjusted so that the compound will be neutral, overall.
