hypervalent_iodine Posted September 18, 2014 Share Posted September 18, 2014 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. 1 Link to comment Share on other sites More sharing options...
LoveTheDivergent Posted October 8, 2014 Share Posted October 8, 2014 Thanks Josie! I assume you need to work out delta H What is ΔH? We haven't been taught this. Link to comment Share on other sites More sharing options...
hypervalent_iodine Posted October 8, 2014 Share Posted October 8, 2014 Thanks Josie! What is ΔH? We haven't been taught this. It refers to change in enthalpy. Link to comment Share on other sites More sharing options...
