Respuesta :

Using the subscripts from the given molecule we can find the symbols of cations, anions as well as number of ions.

Explanation:

CaI₂  =  Ca²⁺ and 2I⁻ ions

Na₂CO₃ = 2 Na⁺ and 1 CO₃²⁻

Ga(ClO₃)₃  = Ga³⁺ and ClO₃⁻

CuF₂  = Cu²⁺ and 2 F⁻

(NH₄)₃PO₄  = 3 NH₄⁺ and PO₄³⁻

FeSO₄   = Fe²⁺ and SO₄²⁻

Mg(NO₃)₂ = Mg²⁺ and NO₃⁻

NH₄NO₂ = NH₄⁺ and NO₂⁻

KC₂H₃O₂= K⁺ and CH₃COO⁻

Na₂Cr₂O₇ = 2Na⁺ and Cr₂O₇²⁻
