• A. Neutralization
• B. Double displacement
• C. Neutralization and double displacement
• D. Combination

Answer 1

The correct option is C Neutralization and double displacement

The chemical reaction $HN{O}_3+KOH\to KN{O}_3+H_{2}O$ is an example of acid base neutralization reaction.
In this reaction nitric acid (a strong acid) reacts with KOH (a strong base) to form $KN{O}_3$ (a salt) and water. Thus, it is a neutralization reaction.
A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react,
and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
In the above reaction, $N{O}_3^{-}$ ion of $HN{O}_3$ and $O{H}^{-}$ ion of $KOH$ switch places to form two new compounds $KN{O}_3$ and $H_{2}O$.
Hence, it is a double displacement reaction.
