Important Thermo Chem Project That I was Absent For


Calculate and show the work of the enthalpy of the reaction, entropy of the reaction, the work of the system(W=P∆V), the change in internal energy, Gibbs free energy for
The Combustion of C19H36O2?
How do I find a complete equation for this? I know it reacts with O2 but that's all. I don't know the delta H, the delta S for C19H36O2!!
I need help.

Write a structural formula for C19H36O2 and figure out what it likely is, ie, an aldehyde, acid, ether, or whatever.

Then write a balanced equation for the complete combustion of the C19H36O2. You can assume it all goes to water and CO2.

Then look up the heats of formation of all reactants and products.

Show us that and we'll go from there.
