2) Fe + HCl

The reaction between iron (Fe) and hydrochloric acid (HCl) can be represented as follows: Fe + 2 HCl → FeCl₂ + H₂

3) Al + H₂SO₄

The reaction between aluminum (Al) and sulfuric acid (H₂SO₄) can be represented as follows: 2 Al + 3 H₂SO₄ → Al₂(SO₄)₃ + 3 H₂

4) Ba + HCl

The reaction between barium (Ba) and hydrochloric acid (HCl) can be represented as follows: Ba + 2 HCl → BaCl₂ + H₂

5) Zn + H₂SO₄

The reaction between zinc (Zn) and sulfuric acid (H₂SO₄) can be represented as follows: Zn + H₂SO₄ → ZnSO₄ + H₂

6) Li₂O + HCl

The reaction between lithium oxide (Li₂O) and hydrochloric acid (HCl) can be represented as follows: Li₂O + 2 HCl → 2 LiCl + H₂O

7) ZnO + HNO₃

The reaction between zinc oxide (ZnO) and nitric acid (HNO₃) can be represented as follows: ZnO + 2 HNO₃ → Zn(NO₃)₂ + H₂O

8) CaO + H₃PO₄

The reaction between calcium oxide (CaO) and phosphoric acid (H₃PO₄) can be represented as follows: CaO + 3 H₃PO₄ → Ca(H₂PO₄)₂ + 3 H₂O

9) MgO + HNO

The reaction between magnesium oxide (MgO) and nitric acid (HNO₃) can be represented as follows: MgO + 2 HNO₃ → Mg(NO₃)₂ + H₂O

10) Fe₃O₄ + H₂SO₄

The reaction between iron(II,III) oxide (Fe₃O₄) and sulfuric acid (H₂SO₄) can be represented as follows: Fe₃O₄ + 4 H₂SO₄ → 3 FeSO₄ + 4 H₂O
