A combustion reaction is a type of redox reaction that occurs when a substance combines with molecular oxygen to make oxygen-containing compounds of other elements in the reaction. One example is the burning of methane, the principal component of natural gas (Figure \(\PageIndex{1}\)). \[CH_4 + 2O_2 \rightarrow CO_2 + 2H_2O \label{Eq1}\] As the reaction proceeds the blue disappears and a copper colored solid appears on the bottom of the container. As the above video shows, placing zinc metal into the copper(II) solution results in a spontaneous redox reaction (\(\Delta G <0\)), and if we placed the copper metal into the zinc solution no reaction would occur (\(\Delta G >0\)).

redox: A short-hand term in chemistry for reactions that involve reduction and/or oxidation (the reducing and oxidizing of chemicals). These are changes that occur with the gain and/or loss of an electron. When something is reduced, one of its atoms gains an electron — to become stable — by stealing it from another atom or molecule.

These two terms have broader meanings now. In all oxidation-reduction reactions, an exchange of electrons occurs—one substance loses electrons while another gains them.

Here, the redox reaction is spontaneous and is responsible for the production of electrical energy. The redox reaction is not spontaneous and electrical energy has to be supplied to initiate the reaction. The two half-cells are set up in different containers, being connected through the salt bridge or porous partition.
