When copper is treated with a certain concentration of nitric acid, nitric oxide and nitrogen dioxide is liberated in equal volumes according to the equation, `xCu + yHNO_3 to Cu(NO_3)_2 + NO + NO_2 + H_2O` . The coefficient of 'x’ and 'y' are

A

2 and 3.

B

2 and 6

C

1 and 3

D

3 and 8

Text Solution

Verified by Experts

The correct Answer is:
B
Balanced equations for producing NO and `NO_2` together is
` 2Cu + 6 HNO_3 to 2Cu (NO_3)_2 +NO_2 +NO +3H_2 O`
Thus, coefficients x and y of Cu and `HNO_3` are 2 and 6, respectively.
