This is the first time I've used this site so I don't know if I'm doing it right... But I need help!!!!! I'm doing Yr 11 Chemistry and our question is this: Explain and evaluate how water's ability to absorb heat is used to measure energy changes in chemical reactions. I need to write a report including a mock-experiment, how i would calculate the molar heat of the soloution etc.

I'm relying on you guys!!!
