Question

Balance the following redox reactions assuming a basic solution. Show all the steps.

a. MnO2(s) -> MnO4^-2 + H2 (g)
b. H2O2 (aq) + Cl2O7 (g) -> ClO2- (aq) + O2 (g)

How can you balance these if for example in part a., there is no H on the left side... can I just add it in?

First, it says basic, not acidic. Yes, you add the OH^- in.
