Question:
When copper is treated with a certain concentration of nitric acid, nitric oxide and nitrogen dioxide are liberated in equal volumes according to the equation,
\[
xCu + yHNO_3 \rightarrow Cu(NO_3)_2 + NO + NO_2 + H_2O
\]
The coefficients of \( x \) and \( y \) are respectively
When copper is treated with a certain concentration of nitric acid, nitric oxide and nitrogen dioxide are liberated in equal volumes according to the equation,
\[
xCu + yHNO_3 \rightarrow Cu(NO_3)_2 + NO + NO_2 + H_2O
\]
The coefficients of \( x \) and \( y \) are respectively
Show Hint
In redox reactions, balance the number of atoms and charges on both sides of the equation to determine the stoichiometric coefficients.
