Balancing Equations for Half-Reactions?
Hello I am trying to learn how to balance equations using high reactions. I have to balance them and identify the half-reaction.
First Example
O2 (g) --> H2O (l)
I get that O2--> H2-2e
Is that correct?

"using high reactions" ---> they are called half reactions.
O2 (g) --> H2O (l)
balance the oxygen
O2 (g) --> 2H2O (l)
balance the hydrogen
4H^+ + O2 (g) --> 2H2O (l)
balance the charge
4e^- + 4H^+ + O2 (g) --> 2H2O (l)
