That's a lot of numbers, Joe.

 

Would you like to say what they mean?

Could you be a little clearer in what your question actually is? I assume you need to work out delta H at some point given the data that you have, so could you please indicate where you are having trouble? We are not in the business of doing a person's homework here, so you will need to show some effort.

Thanks Josie!

What is ΔH? We haven't been taught this.

It refers to change in enthalpy.
