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. the energy used in photosynthesis is light energy, which is captured by pigments in plant cells called chlorophyll. which of the following balanced chemical equations accurately summarizes photosynthesis? 6co₂ + 6h₂o + light energy → c₆h₁₂o₆ + 6o₂ 6co₂ + 6h₂o → c₆h₁₂o₆ + 6o₂ + light energy

Explanation:

Step1: Understand energy - use in photosynthesis

Photosynthesis uses light energy.

Step2: Apply energy - placement rule

Since energy is used, it should be on the reactant side.

Answer:

$6CO_2 + 6H_2O+\text{ light energy}\to C_6H_{12}O_6 + 6O_2$
