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
mg²⁺ po₄³⁻
pb⁴⁺ bro⁻
zn²⁺ no₃⁻

Explanation:

Step1: Determine formula for Mg²⁺ and PO₄³⁻

To balance charges, we need 3 Mg²⁺ ions (total charge +6) and 2 PO₄³⁻ ions (total charge -6). So the empirical formula is Mg₃(PO₄)₂. The name is magnesium phosphate.

Step2: Determine formula for Pb⁴⁺ and BrO⁻

To balance charges, we need 1 Pb⁴⁺ ion and 4 BrO⁻ ions. The empirical formula is Pb(BrO)₄. The name is lead(IV) hypobromite.

Step3: Determine formula for Zn²⁺ and NO₃⁻

To balance charges, we need 1 Zn²⁺ ion and 2 NO₃⁻ ions. The empirical formula is Zn(NO₃)₂. The name is zinc nitrate.

Answer:

cation	anion	empirical formula	name of compound
Pb⁴⁺	BrO⁻	Pb(BrO)₄	lead(IV) hypobromite
Zn²⁺	NO₃⁻	Zn(NO₃)₂	zinc nitrate
