Question

fill in the name and empirical formula of each ionic compound that could be formed from the ions in this table:
some ionic compounds
cation anion empirical formula name of compound
sn^{2 +} o^{2 -}
mn^{3 +} p^{3 -}
fe^{3 +} n^{3 -}
mn^{2 +} s^{2 -}

Explanation:

Step1: Determine formula for Sn²⁺ and O²⁻

The charges of Sn²⁺ and O²⁻ are equal in magnitude. So, the empirical - formula is SnO. The name of the compound is tin(II) oxide.

Step2: Determine formula for Mn³⁺ and P³⁻

The charges of Mn³⁺ and P³⁻ are equal in magnitude. The empirical - formula is MnP. The name of the compound is manganese(III) phosphide.

Step3: Determine formula for Fe³⁺ and N³⁻

The charges of Fe³⁺ and N³⁻ are equal in magnitude. The empirical - formula is FeN. The name of the compound is iron(III) nitride.

Step4: Determine formula for Mn²⁺ and S²⁻

The charges of Mn²⁺ and S²⁻ are equal in magnitude. The empirical - formula is MnS. The name of the compound is manganese(II) sulfide.

Answer:

cation	anion	empirical formula	name of compound
Mn³⁺	P³⁻	MnP	manganese(III) phosphide
Fe³⁺	N³⁻	FeN	iron(III) nitride
Mn²⁺	S²⁻	MnS	manganese(II) sulfide
