Question

The equation for the reaction between copper and nitric acid is

vCu + wHNO3--->xCu(NO3)2 + yNO + zH2O
Balance the equation and find v, w, x, y and z.

Answer 1

v=1

w=4

x=1

y=2

z=2

Step-by-step explanation:

Cu +4HNO₃ ⇒ Cu(NO₃)₂ + 2NO₂+ 2H₂O

Answer 2

3Cu + 8HNO3 —— 3Cu(NO3)2 + 2NO + 4H2O
