Hydrochloric acid interacts with the following of the listed substances: copper, magnesium, copper (II) oxide

Hydrochloric acid interacts with the following of the listed substances: copper, magnesium, copper (II) oxide, silicon (IV) oxide, potassium sulfate, silver nitrate, calcium carbonate. Write down possible equations of reactions in molecular and ionic forms.

magnesium, copper (II) oxide, silver nitrate, calcium carbonate.
1) Mg + 2HCl = MgCl₂ + H₂

Mg⁰ + 2H⁺ + 2Cl⁻ = Mg2⁺ + 2Cl⁻ + H₂O

Mg⁰ + 2H⁺ = Mg2⁺ + H₂⁰

2) 2HCl + CuO = CuCl₂ + H₂O

2H⁺ + 2Cl⁻ + CuO = Cu2⁺ + Cl⁻ + H₂O

2H⁺ + CuO = Cu2⁺ + H₂O

3) HCl + AgNO₃ = AgCl + HNO₃

H⁺ + Cl⁻ + Ag⁺ + NO₃⁻ = AgCl + H⁺ + NO₃⁻

Ag⁺ + Cl = AgCl

4) HCl + CaCO₃ = CaCl₂ + H₂O + CO₂

2H⁺ + 2Cl⁻ + CaCO₃ = Ca2⁺ + 2Cl⁻ + H₂O + CO₂

2H⁺ + CaCO₃ = Ca2⁺ + H₂O + CO₂
