Answer 1

Answer: $HCl+KOH\rightarrow KCl+H_2O$

Explanation:

Neutralization reaction  is defined as the chemical reaction in which an acid reacts with a base to produce a salt and water molecule.

$HX+BOH\rightarrow BX+H_2O$

a) $HCl+KOH\rightarrow KCl+H_2O$ is a neutralization reaction as acid reacts with a base to produce a salt and water molecule.

b) $AgNO_3+KCl\rightarrow AgCl+KNO_3$  is a double displacement reaction as here exchange of ions take place.

c) $CH_4+2O_2\rightarrow CO_2+2H_2O$  is a combustion reaction in which fuel is reacted with oxygen to form carbon dioxide and water.

d) $2K+2H_2O\rightarrow 2KOH+H_2$ is a single replacement reaction in which more reactive element displaces the less reactive element from its salt solution.
