What are the products of a combustion reaction?

From a hydrocarbon, the products are ALWAYS carbon dioxide and water under conditions of complete combustion.

Explanation:

Alkane + oxygen $\rightarrow$ Carbon dioxide and water.

For a specific hydrocarbon, say hexanes:

${C}_{6} {H}_{14} \left(l\right) + \left(\frac{19}{2}\right) {O}_{2} \left(g\right) \rightarrow 6 C {O}_{2} + 7 {H}_{2} O \left(l\right)$

Is the equation above balanced? How do you know?

If heptane, ${C}_{7} {H}_{16}$, were combusted, what would be the stoichiometric equation?
