Answer:

The balanced equation that represents an endothermic reaction is:

2 CH4 (g) + 2 O2 (g) → 2 CO2 (g) + 2 H2O (g)

This is because the reactants (CH4 and O2) have a higher bond energy than the products (CO2 and H2O), meaning that energy must be absorbed in order to break the bonds and form the products. As a result, the reaction is endothermic.
