[Solved] The Equation – Cu + X HNO3 → Cu (NO3 )

Có thể bạn quan tâm

Start with hydrogen since it occurs in only one compound on each side of equation

Hydrogen on LHS = x

Hydrogen on RHS = 4

Replace x by 4

Cu + 4 HNO3 → Cu(NO3 )2 + y NO2 + 2 H2O

Now balance nitrogen

Nitrogen on LHS = 4

Nitrogen on RHS = 2 + y

Replace y by 2

Cu + 4 HNO3 → Cu(NO3 )2 + 2 NO2 + 2 H2O

The equation is balanced. Download Solution PDF Share on Whatsapp
