# Stearic Acid combustion

My friend and I are stuck on a lab-work, where we are to find the enthalpy of combustion for stearic acid.

Does anyone know the reaction formula for the combustion of stearic acid?

I'm sure that a full combustion of an organic compound containing only C,H & O would produce (beside the heat,exothermal reaction) $\mbox{CO}_{2}\uparrow$ and $\mbox{H}_{2}\mbox{O} \uparrow$...

So the reaction would require knowledge of the stearic acid structural formula and a know-how to balance the reaction...
