Detailed explanation-1: -Reacting Copper Oxide with Sulphuric Acid Copper (II) oxide reacts with sulfuric acid to create water and copper (II) sulfate. This reaction could be classified as a double displacement reaction or a neutralization reaction.

Detailed explanation-2: -It is a double displacement reaction, in which hydrogen is more reactive than copper and hence it can displace copper from its compound. Therefore, this reaction is possible and the products formed will be copper sulfate and water respectively.

Detailed explanation-3: -CuO + H 2 SO 4 → CuSO 4 + H 2 O.

Detailed explanation-4: -For example, when sodium hydroxide (NaOH) is treated with hydrochloric acid (HCl), then a salt, i.e., sodium chloride (NaCl) and water ( H2O) are obtained. The chemical equation for the neutralization reaction is given as: NaOH+HCl⟶NaCl+H2O. Q.
