Hydrogen peroxide decomposes to water and oxygen at constant pressure by the following reaction:
2H2O2 (l) -> 2H2O (l) + O2 (g) ΔH = -196 kJ
Calculate the value of ΔH (kJ) in this exothermic reaction when 3.50 g of hydrogen peroxide decomposes at constant pressure?
220.2 kJ
1.65 kJ
-0.0248 kJ
2.02 * 10 kJ
-0.1 kJ
