Question

copper+concentrated nitric acid = copper nitrate+nitrogen dioxide+water
balance the chemical equation

Answer 1

Answer:

Cu+2HNo3=CuNo4+No2+H2O

Cu=1

H=2

No=6

Answer 2

Explanation:

The valency of copaper for compounds is 2 but not for Cl

so it =

Cu + 4conc.Hno3 ====> Cu(No3)2 + 2No2 + 2H20

On Both the sides -

> Cu = 1

> H = 4

> N = 4

> O = 12
