Q. The stoichiometric constants for the reaction
$pC u + q H N O_{3} \to r C u (N O_{3})_{2} + s NO + t H_{2} O$
$p$ , $q$ , $r$ , $s$ and $t$ respectively are

3, 3, 3, 2, 3

3, 2, 3, 2, 4

3, 8, 3, 2, 4

2, 3, 3, 3, 2

Multiply Cu term with $3$ and $N$ term with $2$
$3 C u + 2 H N O_{3} \to 3 C u (N O_{3})_{2} + 2 NO + H_{2} O$
Balance $H$ and $O$
$3 C u + 8 H N O_{3} \to 3 C u (N O_{3})_{2} + 2 NO + 4 H_{2} O$
