Write down the reaction equations: a) hydrochloric acid + sodium hydroxide → sodium chloride + water; b) calcium oxide + sulfuric acid → calcium sulfate + water; c) copper sulfate + zinc → zinc sulfate + copper

a) A chemical reaction takes place between substances such as hydrochloric acid and sodium hydroxide. As a result of a chemical reaction, we get sodium chloride salt and water.

НСl + NaОН = NaCl + Н2О

b) A chemical reaction takes place between substances such as calcium oxide and sulfuric acid. As a result of the reaction, calcium sulfate is formed and water is released;

CaO + H2SO4 = CaSO4 ↓ + H2O

c) Chemical interaction between copper sulfates and zinc. As a result of the reaction, we obtain zinc sulfate salt and pure copper.

Zn + CuSO4 = ZnSO4 + Cu.
