$C u + H N O_{3} \to C u {(N O_{3})}_{2} + N O_{2} + H_{2} O$

Step 1

All elements must have the same number of atoms in each side of the equation so that the law of conservation of mass is satisfied and the chemical equation is balanced.

$C u + 4 H N O_{3} \to C u {(N O_{3})}_{2} + 2 N O_{2} + 2 H_{2} O$
