Which equation represents a neutralization reaction? A. 4Fe(s) + 3O2(g) → 2Fe2O3(s) B. 2H2(g) + O2(g) → 2H2O() C. HNO3(aq) + KOH
devlian [24]

Answer : The correct option is, (C)

Explanation :

A. 4Fe(s)+3O_2(g)\rightarrow 2Fe_2O_3(s)

This is synthesis reaction in which the two or more reactant react to give a single product.

B. 2H_2(g)+O_2(g)\rightarrow 2H_2O(l)

This is combination reaction in which the two reactants combine to form a single product.

C. HNO_3(aq)+KOH(aq)\rightarrow KNO_3(aq)+H_2O(l)

This is a neutralization reaction in which an acid react with a base to give a salt and water as a product.

D. AgNO_3(aq)+KCl(aq)\rightarrow KNO_3(aq)+AgCl(s)

This is a double displacement reaction in which the positive cation and negative anion of two reactants exchange their places to give two new products.

Hence, the reaction (C) is a neutralization reaction.
