Explanation: The mitochondria are vacuoles and ribosomes are in both plant and animal cell
The rate of formation of water and the decomposition of hydrogen peroxide is double as compared to rate of formation of oxygen.
<h3>What is chemical reaction?</h3>
The chemical reaction is given as the reaction of the reactants in the process to form the new compound.
The chemical reaction with the decomposition of hydrogen peroxide is:
The rate of formation of water is given to be double the rate of formation of oxygen as 2 moles of water formed with 1 mole of oxygen.
The rate of disappearance of hydrogen peroxide is double with formation of oxygen as for decomposition of 2 moles of hydrogen peroxide, 1 mole of oxygen is formed.

The first step is to convert the 55 kg of Fe₃O₄ to moles by using the molar mass, that is, 231.55 g/mol (55 kg = 55000 gms),
55000 gms × 1 mole / 231.55 gms = 237.53 moles of Fe₃O₄
For the decomposition of every 1 mole of Fe₃O₄, +1118 kJ of energy is needed. Therefore, the energy needed to decompose 237.53 moles will be:
237.53 moles of Fe₃O₄ × 1118 kJ / 1 mole = 265558 kJ
Thus, there is a need of 265558 kJ of energy to decompose 55 kg of Fe₃O₄.
