When hydrogen peroxide (H2O2) is used in rocket fuels, it produces water, oxygen, and heat. 2H2O2(l)⟶2H2O(l)+O2(g)ΔH=−196kJ Part B: How many kilojoules are released when 3.05 moles of H2O2 reacts? Express your answer with the appropriate units. Part C: How many kilojoules are released when 277 g of O2 is produced? Express your answer with the appropriate units.
dilute aqueous hydrogen peroxide is used as a bleaching agent and for disinfecting surfaces and small Enter your answer in the provided box. Dilute aqueous hydrogen peroxide is used as a bleaching agent and for disinfecting surfaces and small cuts. Its concentration is sometimes given as a certain number of "volumes hydrogen peroxide," which refers to the number of volumes of Oz gas, measured at STP, that a given volume of hydrogen peroxide solution will release when it decomposes to...
