Answer : Option D) Chemical energy.
Explanation : The chemical equation
In this reaction it is clear that 6 molecules of oxygen when combines with one molecule of glucose it produces 6 molecules of carbon dioxide and 6 molecules of water along with the generation of energy.
This is a pure chemical energy transformation reaction, as from the chemicals the energy is getting generated. Therefore, It is oxygen and glucose which helps in generating the energy.
So, the energy that is released by cellular respiration is in the form of chemical energy.
Answer:
The expression to calculate the mass of the reactant is
Explanation:
<em>The amount of heat released is equal to the amount of heat released per gram of reactant times the mass of the reactant.</em> To keep to coherence between units we need to transform 1,080 J to kJ. We do so with proportions:
Then,
