Liquid hydrogen peroxide, an oxidizing agent in many rocket fuel mixtures,releases oxygen gas on decomposition

Question by iamjussosweet: Liquid hydrogen peroxide, an oxidizing agent in many rocket fuel mixtures,releases oxygen gas on decomposition
2 H2O2(l) = 2 H2O(l) + O2(g) Hrxn = -196.1 kJ

How much heat is released when 615 kg H2O2 decomposes?

Best answer:

Answer by Dennis M
H2O2(l) = H2O(l) + 1/2 O2(g) + 98.05 kJ / mole

98.05 kJ / mole X 1 mole / 34 g X 615 kg X 1000 g / kg = 1.77 X 10^6 kJ

Answer: 1.77 X 10^6 kJ
