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 the 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 chemical equations accurately includes \energy\? glucose + oxygen → carbon dioxide + water + energy glucose + oxygen + energy → carbon dioxide + water save answer

Explanation:

The process of glucose and oxygen reacting to form carbon dioxide and water is cellular respiration, which releases energy (like in the breakdown of glucose for energy). So more energy is released than used, so "energy" should be on the products side. The first equation has "energy" with products (carbon dioxide + water + energy), while the second has it with reactants (which would be for a process using more energy, like photosynthesis reverse, but cellular respiration releases energy). So the first equation is correct.

Answer:

glucose + oxygen → carbon dioxide + water + energy
