Hydrogen peroxide, H2O2, is a colorless liquid whose solutions are used

Hydrogen peroxide, H2O2, is a colorless liquid whose solutions are used as a bleach and an antiseptic. H2O2 can be prepared in a process whose overall change is H2(g)+O2(g)H2O2(l) Calculate the enthalpy change using the following data: H=2H2O2(l)2H2O(l)+O2(g);H=196.0kJH2(g)+21O2(g)H2O(l);H=285.8kJkJ
