# What does pentane plus (C_5H_12) oxygen yield?

${C}_{5} {H}_{12} \left(l\right) + 8 {O}_{2} \left(g\right) \rightarrow 5 C {O}_{2} \left(g\right) + 6 {H}_{2} O + \Delta$
Is this balanced? How do you represent the combustion of heptane, ${C}_{7} {H}_{16}$?
Also try to represent the combustion of hexanes, ${C}_{6} {H}_{14}$; in this instance (an even-numbered alkane), you have to use fractional coefficients, or double the equation.
