Question

plants turn sunlight into energy through a process called photosynthesis, which can be represented by the chemical equation: $6\ce{co_2} + 6\ce{h_2o} + \text{light energy} \
ightarrow \ce{c_6h_{12}o_6} + 6\ce{o_2}$. which of the following correctly identifies the reactants and products of this process? reactants: $\ce{c_6h_{12}o_6}$, $\ce{o_2}$; products: $\ce{co_2}$, $\ce{h_2o}$, light energy reactants: $\ce{co_2}$, $\ce{h_2o}$, light energy; products: $\ce{c_6h_{12}o_6}$, $\ce{o_2}$ reactants: $\ce{co_2}$, $\ce{o_2}$, light energy; products: $\ce{h_2o}$, $\ce{c_6h_{12}o_6}$ reactants: $\ce{o_2}$, $\ce{h_2o}$, $\ce{c_6h_{12}o_6}$; products: $\ce{co_2}$, light energy

Explanation:

Step1: Recall chemical equation components

In a chemical equation, reactants are on the left side of the arrow, and products are on the right side. The equation is \(6\text{CO}_2 + 6\text{H}_2\text{O}+\text{light energy}
ightarrow\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2\).

Step2: Identify reactants and products

Reactants: Substances before the arrow (\(6\text{CO}_2\), \(6\text{H}_2\text{O}\), light energy). Products: Substances after the arrow (\(\text{C}_6\text{H}_{12}\text{O}_6\), \(6\text{O}_2\)). Now check the options:

• First option: Reactants and products are reversed (shows products as reactants and vice - versa).
• Second option: Reactants are \(\text{CO}_2\), \(\text{H}_2\text{O}\), light energy (left side) and products are \(\text{C}_6\text{H}_{12}\text{O}_6\), \(\text{O}_2\) (right side) which matches the equation.
• Third option: Incorrectly identifies products (misses \(\text{O}_2\) and includes wrong substances).
• Fourth option: Reactants and products are reversed.

Answer:

The option with "Reactants: \(\text{CO}_2\), \(\text{H}_2\text{O}\), light energy; Products: \(\text{C}_6\text{H}_{12}\text{O}_6\), \(\text{O}_2\)" (the second option among the given ones).
