Question

Redox reactions can be written as two half-reactions, focusing on the gain or loss of electrons by one of the chemical substances. One half-reaction shows the oxidation while the other shows the reduction. When the two half-reactions are combined, the overall reaction is obtained.
The half-reactions can aid in the balancing of redox equations because the number of each element must be balanced as well as the number of electrons gained and lost.
