Answer 1

The solution is as follows:

1. KCl (aq) + AgNO_​3(aq) $\to$ KNO₃(aq) + AgCl(s)

2. Al(OH)₃(aq) + 3 NaNO₃(aq) $\to$ Al(NO₃)₃(aq) + 3 NaOH(aq)

3. Fe(s) + CuSO₄(aq) $\to$ FeSO₄(aq) + Cu(s)

4. 2 Al(s) + 3 CuCl₂(aq) $\to$ 2 AlCl₃(aq) + 3 Cu (s)

5. 2 KBr (s) $\to$ 2 K (s) + Br₂(g)

6. CaCO₃(s) $\to$CaO(s) + CO₂(g)

7. 2 Zn(s) + O₂(g) $\to$ 2 ZnO(s)

8. 2 Na(s) + Cl₂(g) $\to$ 2 NaCl(s)

9. Al₂(SO₄)₃ (aq) + 3 BaCl₂(aq) $\to$ 2 AlCl₃(aq) + 3 BaSO₄(s)

10. 2 NaHCO₃(s) $\to$ Na₂CO₃(s) + CO₂(g) + H₂O(l)
