Question

The reaction of zinc with dilute and concentrated nitric acid, respectively, produces:

• A. $N{O}_2$ and $NO$
• B. $NO$ and $N{O}_2$
• C. $N{O}_2$ and $N_{2}O$
• D. $N_{2}O$ and $N{O}_2$

Answer 1

The correct option is D $N_{2}O$ and $N{O}_2$

$Zn+HN{O}_3(dil.)\to Zn\left(N{O}_3{)}_2\right(aq)+N_{2}O+H_{2}O$
$Zn+HN{O}_3(conc.)\to Zn(N{O}_3{)}_2+N{O}_2+H_{2}O$
