| 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
