Answer 1

The correct formulas for the given ionic compounds are sodium acetate: NaC₂H₃O₂ and ammonium phosphate: (NH4)₃PO₄. These formulas are determined through the charges of the ions they consist of.

Step-by-step explanation:

The correct formulas for the given ionic compounds are sodium acetate: NaC₂H₃O₂ and ammonium phosphate: (NH4)₃PO₄. In chemistry, the formula for an ionic compound is determined by the charges of the ions involved. Sodium ion has a +1 charge, so it pairs with the acetate ion, which has a -1 charge, resulting in an equal but opposite total charge, hence the formula is NaC₂H₃O₂. Similarly, ammonium ion (NH4⁺) has a +1 charge and phosphate ion (PO₄³⁻) has a -3 charge. Therefore, you need three ammonium ions to balance one phosphate ion and the formula becomes (NH4)₃PO₄.
