Write the half-reaction, the balanced equation for the cell reaction, and the cell diagram for the following skeletal equations:
c) Cl2(g) + H2(g) -> HCl(aq)

I don't understand why it doesn't split into the two half reactions:
1) Cl2 -> HCl
2) H2 -> HCl

Also, an explanation would help. Thanks!

I think it is because the change in oxidation state of H2 is associated with the hydrogen part of hydrochloric acid. And the oxidation state of Cl2 is associated with the chlorine part of hydrochloric acid. Due to this, you have to keep them separate.
