Final answer:

The formulas for the given compounds are based on the charges of the ions, ensuring the overall charge is neutral. For instance, rubidium nitrite is RbNO₂, potassium sulfide is K₂S, and magnesium phosphate is Mg₃(PO₄)₂.

Step-by-step explanation:

To write the formulas for the given compounds, we need to consider the charges of the ions that they consist of. The ions must combine in a way that the overall charge of the compound is neutral. Here are the formulas for the requested compounds:

  • (a) Rubidium nitrite: RbNO₂
  • (b) Potassium sulfide: K₂S
  • (c) Sodium hydrogen sulfide: NaHS
  • (d) Magnesium phosphate: Mg₃(PO₄)₂
  • (e) Calcium hydrogen phosphate: CaHPO₄
  • (f) Lead(II) carbonate: PbCO₃
  • (g) Tin(II) fluoride: SnF₂
  • (h) Ammonium sulfate: (NH₄)₂SO₄
  • (i) Silver perchlorate: AgClO₄
  • (j) Boron trichloride: BCl₃

Each formula corresponds to the stoichiometry dictated by the charges of the ions involved.
