Question

scientists sometimes want to show whether more energy is used or released during a chemical process. they do this by adding the word energy to the chemical equation. if more energy is used than is released during a chemical process, \energy\ should appear on the same side of the equation as the reactants. if more energy is released than is used, \energy\ should appear on the same side of the equation as the products. which of the following balanced chemical equations accurately summarizes cellular respiration? $c_{6}h_{12}o_{6}+6o_{2}\to 6co_{2}+6h_{2}o + energy$ $c_{6}h_{12}o_{6}+6o_{2}+energy\to 6co_{2}+6h_{2}o$

Explanation:

Cellular respiration is an exothermic process where energy is released. According to the given rule, if more energy is released than used, "energy" should be on the product side. In the first equation \(C_{6}H_{12}O_{6}+6O_{2}\to6CO_{2}+6H_{2}O + energy\), energy is on the product side which is correct for cellular respiration. In the second equation \(C_{6}H_{12}O_{6}+6O_{2}+energy\to6CO_{2}+6H_{2}O\), energy is on the reactant side which would imply energy is being used (like in photosynthesis, an endothermic process), not released as in cellular respiration.

Answer:

\(C_{6}H_{12}O_{6}+6O_{2}\to6CO_{2}+6H_{2}O + energy\)
