The answer would be 833.7
No because they are both made up of H2O molecules; they only have different physical properties, one is in liquid state while the other is in solid state
Answer:
4.3 x 10⁶ kJ are released
Explanation:
From the balanced chemical equation we know that when 2 moles of hydrogen peroxide decompose, 191 kJ of heat are released. So what we need to calculate is the number of moles the 765 kg of H2O2 represent and calculate the heat released.
Molar Mass H2O2 = 34.01 g/mol
Mass H2O2 = 765 Kg x 1000 g/Kg = 765000 g
moles H2O2 = 1 Mol / 34.01 g x 765000 grams = 22.5 Mol
(-196.1 kJ/ 2 mol H2O2 ) x 22.5 mol H2O2 = -4.3 x 10⁶ kJ
