Question

When copper is heated with $conc.HN{O}_3$, it produces

• A. $Cu(N{O}_3{)}_2$ and $NO$
• B. $Cu(N{O}_3{)}_2,NO$ and $N{O}_2$
• C. $Cu(N{O}_3{)}_2$ and $N_{2}O$
• D. $Cu(N{O}_3{)}_2$ and $N{O}_2$

Answer 1

The correct option is D

$Cu(N{O}_3{)}_2$ and $N{O}_2$

$Cu+\underset{\left(conc\right)}{4HN{O}_3}\to Cu(N{O}_3{)}_2+2N{O}_2+2H_{2}O$
