Hydrogen peroxide, H2 O2, is a colorless liquid whose solutions are used as a bleach and an antiseptic. H2 O2 can be prepared in a process whose overall change is H2 (g) + O2 (g) –→ H2O2 (1) Calculate the enthalpy change using the following data: 2H2О2(1) — 2H,0() + О-(9); дн: -196.0 kJ На (9) + 3 О2(9) > H20(1); дН — — 285.8 kJ = - ΔΗ - kJ
