Question

Zn + HNO3=Zn(NO3)2+NH4NO3+H2O

how to balance this equation by ione electron method?​

Answer 1

Explanation:

Balance the nitrogen atoms first by multiplying the nitric acid by 2. Since you're in acidic solution, you can balance the hydrogen atoms by adding protons, H+ , to the side that lacks hydrogen, and oxygen atoms by adding water molecules to the side that lacks oxygen.
