Answer 2

Chemical Reactions

1) ZnSO4 + MgCl2 The reaction between ZnSO4 (zinc sulfate) and MgCl2 (magnesium chloride) involves a double displacement reaction, also known as a double replacement reaction. In this reaction, the positive ions of the two ionic compounds switch places to form two new compounds.

The balanced chemical equation for this reaction is: ``` ZnSO4 + MgCl2 → ZnCl2 + MgSO4 ```

This reaction can be represented as the exchange of ions: ``` Zn2+ + SO4^2- + Mg^2+ + 2Cl^- → Zn^2+ + 2Cl^- + Mg^2+ + SO4^2- ```

This reaction results in the formation of zinc chloride (ZnCl2) and magnesium sulfate (MgSO4).

2) MgCl2 + H3PO4

The reaction between MgCl2 (magnesium chloride) and H3PO4 (phosphoric acid) also involves a double displacement reaction.

The balanced chemical equation for this reaction is: ``` MgCl2 + 2H3PO4 → Mg(H2PO4)2 + 2HCl ```

This reaction can be represented as the exchange of ions: ``` Mg^2+ + 2Cl^- + 2H^+ + 2H2PO4^- → Mg^2+ + 2H2PO4^- + 2H^+ + 2Cl^- ```

This reaction results in the formation of magnesium dihydrogen phosphate (Mg(H2PO4)2) and hydrochloric acid (HCl).

3) HNO3 + Fe(OH)3

The reaction between HNO3 (nitric acid) and Fe(OH)3 (iron(III) hydroxide) involves an acid-base reaction.

The balanced chemical equation for this reaction is: ``` 3HNO3 + Fe(OH)3 → Fe(NO3)3 + 3H2O ```

This reaction can be represented as the exchange of ions: ``` 3H^+ + 3NO3^- + Fe^3+ + 3OH^- → Fe^3+ + 3NO3^- + 3H2O ```

This reaction results in the formation of iron(III) nitrate (Fe(NO3)3) and water (H2O).

These reactions involve the rearrangement of atoms and ions to form new compounds based on the principles of chemical bonding and reactivity.
