1. The problem statement, all variables and given/known data
Determine the enthalpy of combustion of Magnesium.

Mg + 1/2O2 --> MgO

magnesium + half oxygen -> magnesium oxide.


3. The attempt at a solution

I am not sure how to calculate this since I don't know where to start. Is there a specific value for this? Or, is there a way we could get these values from a chart or somewhere?

I need help. Thanks.

Review the definition of heat of formation and then reexamine your combustion equation.

They should be at the back of your book or try the Index if all fails.

Thanks very much guys for your responses. I found it on the net and basically I had to look for enthalpy of formation of MgO to get my answer. It's -601 kJ.
