# What energy results when "n-butane" is combusted?

What energy results when "n-butane" is combusted?

Answer 1

And where are the data...?

#### Explanation:

You want the enthalpy associated with the reaction...

${C}_{4} {H}_{10} \left(g\right) + \frac{13}{2} {O}_{2} \left(g\right) \rightarrow 4 C {O}_{2} \left(g\right) + 5 {H}_{2} O \left(l\right) + \Delta$

This site quotes for butane, $\Delta {H}_{\text{combustion}}^{\circ} = - 2.88 \times {10}^{3} \cdot k J \cdot m o {l}^{-} 1$...in this instance $k J \cdot m o {l}^{-} 1$ means PER MOLE of reaction as written.
