When hydrogen peroxide (H2O2) is used in rocket fuels, it produces water, oxygen, and heat.
2H2O2(l) → 2H2O(l) + O2(g) ΔH = −196 kJ
a. Is the reaction endothermic or exothermic?
b. How many kilojoules are released when 2.50 mol of H2O2 reacts?
c. How many kilojoules are released when 275 g of O2 is produced?
