$\text{Balance mass, balance charge............}$

Explanation:

${C}_{3} {H}_{8} + 5 {O}_{2} \left(g\right) \rightarrow 3 C {O}_{2} \left(g\right) + 4 {H}_{2} O \left(l\right)$

I assume you mean propane, ${C}_{3} {H}_{8}$?

How does energy transfer in this reaction? Where should you place a $\Delta$ symbol?

The given reaction represents complete combustion. Shorter hydrocarbons, such as propane, usually undergo complete oxidation.
