3MgCl2 +2 H3PO4 -> Mg3(PO4)2 +6 HCl
3Mg(+2) + 6Cl(-) + 6H(+) + 2PO4(-3) -> Mg3(PO4)2 + 6H(+) + 6Cl(-)
3Mg(+2) + 2PO4(-3) -> Mg3(PO4)2

3HNO3 + Fe(OH)3 -> Fe(NO3)3 + 3H2O
3H(+) + 3NO3(-) + Fe(OH)3 -> Fe(+3) + 3NO3(-) + 3H2O
3H(+) + Fe(OH)3 -> Fe(+3) + 3H2O

Answer 2

Reaction 1: ZnSO4 + MgCl2

The reaction between zinc sulfate (ZnSO4) and magnesium chloride (MgCl2) can be represented as follows:

ZnSO4 + MgCl2 → ZnCl2 + MgSO4

In this reaction, zinc sulfate reacts with magnesium chloride to form zinc chloride and magnesium sulfate.

Reaction 2: MgCl2 + H3PO4

The reaction between magnesium chloride (MgCl2) and phosphoric acid (H3PO4) can be represented as follows:

MgCl2 + H3PO4 → Mg(H2PO4)2 + HCl

In this reaction, magnesium chloride reacts with phosphoric acid to form magnesium dihydrogen phosphate and hydrochloric acid.

Reaction 3: HNO3 + Fe(OH)3

The reaction between nitric acid (HNO3) and iron(III) hydroxide (Fe(OH)3) can be represented as follows:

HNO3 + Fe(OH)3 → Fe(NO3)3 + H2O

In this reaction, nitric acid reacts with iron(III) hydroxide to form iron(III) nitrate and water.
