Answer:
You need to have a clean surface for contact between the solution and the material.
Explanation:
The presence of impurity on the surface of the material, and lack of surface uniformity (smoothness) can reduce the effective contact between material and solution and can interfere with the electroplating process's success.
Answer:
N2 = 2 atoms.
2H2 = 4 atoms.
NH3 = 4 atoms.
Also: this is an uneven chemical equation, make sure there are the same amount of atoms on each side (in total).
