Homework Help: chem expirement!

Posted by rob on Thursday, May 17, 2007 at 12:28pm.

You are required to design an experiment to test Hess's law using the combustion of ethanol. Write a brief design for this experiment.

What I wrote as my answer:

Hessí Law: is the algebraic addition of chemical equations yields a net equation whose enthalpy of reaction is the algebraic sum of the individual enthalpies of reaction: ∆H net =[sum]∆H
The following experiment is a test of Hessís law using combustion of Ethanol.
To test this and the acceptability of Hessís law, the molar enthalpy of combustion of Ethanol is determined calorimetrically.

I don't know the full particulars of the problem or how much is to be written but I find it to be sparse.
