Answer
- Sulphuric acid + Zinc → Zinc Sulphate solution + Hydrogen gas H2SO4(aq) + Zn(s) → ZnSO4 (aq) + H2(g)
- Hydrochloric acid + Magneisum → Magnesium chloride solution + Hydrogen gas 2HCl(aq) + Mg(s) → MgCl2(aq) + H2(g)
- Sulphuric acid + Aluminium → Aluminium sulphate solution + Hydrogen gas 3H2SO4(aq) + 2Al(s) → Al2(SO4)3(aq) + H2(g)
- Hydrochloric acid + Iron → Iron(III) Chloride solution + Hydrogen gas 6HCl(aq) + 2Fe(s) → 2FeCl3(aq) + 3H2(g)
