Which of the following substances: sodium carbonate, zinc oxide, phosphorus (V) oxide, potassium hydroxide, copper (II) nitrate, silver nitrate, sulfuric acid can interact with hydrochloric acid. Write down the reaction equations in molecular and ionic form.

Acids react with salts of weaker acids (Na2CO3 – sodium carbonate, silver nitrate Ag NO3), basic, amphoteric oxides (zinc oxide ZnO), bases (potassium hydroxide KOH).

Na2CO3 + 2HCl = 2NaCl + H2O + CO2.

2 Na +1+ CO3-2 + 2H+1 + 2Cl -1= 2Na+1 + 2Cl-1 + H2O + CO2.

2H+1 + CO3-2 = H2O + CO2.

ZnO + 2HCl = ZnCl2 + H2O.

ZnO + 2H+1 + 2Cl-1 = Zn+2 + 2Cl-1 + H2O.

ZnO + 2H+1 = Zn+2 + H2O.

KOH + HCl = KCl + H2O.

K+1 + OH-1 + H+1 + Cl-1 = K+1 + Cl-1 + H2O.

H+1 + OH-1 = H2O.

Ag NO3 + HCl = AgCl + HNO3.

Ag+1 + NO3-1 + H+1 + Cl-1 = AgCl + H+1 + NO3-1.

Ag+1 + Cl-1 = AgCl.
