Answer
The complete balanced equations are as follows:
Work Step by Step
When Hydrocarbon undergoes combustion reaction with Oxygen, the end products will be Carbon dioxide and Water. Before balancing the equations, we have to convert the structural formula into molecular formula so that the balancing will be easy. After that, balancing both side will be done by putting numbers (stoichiometry) before molecules , if necessary, so that no. of atoms for each atom will be same on both side.
