Asked by Tabetha
Here's a molar heat problem I just have one question on. How much heat will be transferred if 2 moles of hydrogen reacts with excess oxygen according to the reaction below?
2H2 + O2 yields 2H20 + 572 kJ
The answer according to my answer key is
2 mole H2 x 572 kJ/2moles H2.
I understand where the first 2 moles comes from, but what about the second one on the bottom of the equation? I heard there's a chart online that tells you where to find this value. Could you show me a link if there's a such chart? Thanks for your help!
