hydrogen peroxide can decompose to water and oxygen by following reaction:
2H2 O2 (l) = 2H2 O(l) + O2(g) deltaH= -196kJ
CALCULATE THE VALUE OF q when 5.00g of H2 O2(l) decomposes at constant pressure.
my answer is -14.4J...can some please tell me how to do this again because I forgot what step I took and it have a similar question on another homework
