hi I'm taking GCE O levels so this might give you an idea of my level of chemistry. For a reaction like 2H2O2-->2H2O+O2 and the question tells me it has an ΔH=-98kJ/mol so does it mean that when 2 moles of hydrogen peroxide decomposes to form water and oxygen, the net amount of heat generated is 98kJ? So if i half the equation into H2O2-->H2O+1/2O2 the ΔH=-39kJ?
Thanks for the help!
