To determine the products in the chemical equation for photosynthesis, we need to look at the complete balanced equation for photosynthesis. Photosynthesis is the process by which green plants use sunlight to synthesize nutrients from carbon dioxide and water. The overall chemical equation for photosynthesis is:
[tex]\[ 6 \, \text{CO}_2 + 6 \, \text{H}_2\text{O} + \text{light energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6 \, \text{O}_2 \][/tex]
Breaking this down:
- On the left side of the equation (reactants), we have:
- 6 molecules of carbon dioxide ([tex]\(\text{CO}_2\)[/tex])
- 6 molecules of water ([tex]\(\text{H}_2\text{O}\)[/tex])
- On the right side of the equation (products), we have:
- 1 molecule of glucose ([tex]\(\text{C}_6\text{H}_{12}\text{O}_6\)[/tex])
- 6 molecules of oxygen ([tex]\(\text{O}_2\)[/tex])
Now, let's review the given options to identify which correctly represents the products:
1. [tex]\( \text{O}_2 + 6 \, \text{CO}_2 \)[/tex]: This option incorrectly shows one of the reactants (carbon dioxide) instead of the products.
2. [tex]\( \text{C}_6\text{H}_{12}\text{O}_6 + 6 \, \text{H}_2\text{O} \)[/tex]: This option incorrectly includes water, which is a reactant, not a product.
3. [tex]\( 6 \, \text{CO}_2 + 6 \, \text{H}_2\text{O} \)[/tex]: This option lists the reactants instead of the products.
4. [tex]\( \text{C}_6\text{H}_{12}\text{O}_6 + 6 \, \text{O}_2 \)[/tex]: This option correctly lists the products of glucose and oxygen.
Therefore, the correct representation of the products in the chemical equation for photosynthesis is:
[tex]\[ \text{C}_6\text{H}_{12}\text{O}_6 + 6 \, \text{O}_2 \][/tex]
So, the correct option is number 4.
