Write the formulas for each of the ionic compound formed from the given cation and anion. Na+ and phosphate anion (PO3-/4), Ba2+ and bicarbonate anion (HCO3)

Answer 1

The formulas for the ionic compounds formed from the given cation and anion are:

1. Na+ and phosphate anion (PO3-/4):
The charge on sodium ion (Na+) is +1 and the charge on the phosphate anion (PO3-/4) is -3. To balance the charges, we need three Na+ ions to combine with one phosphate anion. Thus, the formula for the ionic compound is Na3PO4.

2. Ba2+ and bicarbonate anion (HCO3-):
The charge on barium ion (Ba2+) is +2 and the charge on the bicarbonate anion (HCO3-) is -1. To balance the charges, we need two Ba2+ ions to combine with one bicarbonate anions. Thus, the formula for the ionic compound is Ba(HCO3)2.
