To determine how the reactants are represented in the chemical equation for photosynthesis, we need to understand the process of photosynthesis itself.
Photosynthesis is a process used by plants, algae, and certain bacteria to harness energy from sunlight and convert it into chemical energy. During photosynthesis, the reactants are substances that are consumed to produce the final products.
The general chemical equation for photosynthesis is:
[tex]\[ 6CO_2 + 6H_2O + Light \: Energy \rightarrow C_6H_{12}O_6 + 6O_2 \][/tex]
In this equation:
- Carbon dioxide ([tex]\(CO_2\)[/tex]) and water ([tex]\(H_2O\)[/tex]) are the reactants.
- Glucose ([tex]\(C_6H_{12}O_6\)[/tex]) and oxygen ([tex]\(O_2\)[/tex]) are the products.
Given the options:
1. [tex]\(6 CO_2 + O_2\)[/tex]
2. [tex]\(6 CO_2 + 6 H_2 O\)[/tex]
3. [tex]\(C_6 H_{12} O_6 + 6 O_2\)[/tex]
4. [tex]\(C_6 H_{12} O_6 + 6 H_2 O\)[/tex]
We see that the correct representation of the reactants for photosynthesis is:
[tex]\[ 6 CO_2 + 6 H_2 O \][/tex]
Thus, the correct choice is:
[tex]\[ \boxed{6 CO_2+6 H_2 O} \][/tex]
