Question

What are the reactants in the following reactions?

$KOH\left(aq\right)+HN{O}_3\left(aq\right)\to H_{2}O\left(l\right)+KN{O}_3\left(aq\right)$

• A. $H_{2}O$ , $KN{O}_3$
• B. $HN{O}_3$ , $H_{2}O$
• C. $KOH$ , $HN{O}_3$
• D. $KN{O}_3$ , $KOH$

Answer 1

The correct option is C

$KOH$ , $HN{O}_3$

The reactants for the reaction are $KOH$ and $HN{O}_3$ because they react chemically to produce the products $H_{2}O$ and $KN{O}_3$.

$KOH\left(aq\right)+HN{O}_3\left(aq\right)\to H_{2}O\left(l\right)+KN{O}_3\left(aq\right)$ (reactants) (products)

Moreover, whenever a chemical equation is written, the molecules which lie to the left side of the arrow are the reactants and those which lie to the right side are products.
