Question

the chemical reaction equation of photosynthesis is shown here:
6co₂ + 6h₂o → c₆h₁₂o₆ + 6o₂
what information is not given in this equation.
○ it does not show if the reaction is reversible
○ it does not show the reactants needed for the reaction
○ it does not show that photosynthesis consists of many separate steps.
○ it does not show the number of molecules required to produce glucose.

Explanation:

1. Analyze Option 1: The equation uses a one - way arrow, but the lack of a reversible arrow (⇌) doesn't mean this is the main missing info here. The key is about the complexity of the reaction steps.
2. Analyze Option 2: The reactants ($\ce{CO_2}$ and $\ce{H_2O}$) are clearly shown on the left side of the equation, so this is incorrect.
3. Analyze Option 3: The given equation is a simplified overall reaction. Photosynthesis actually has two main stages (light - dependent and light - independent) and many sub - steps, which the single - step equation does not show. This is a valid point about what's missing.
4. Analyze Option 4: The coefficients (6 for $\ce{CO_2}$, 6 for $\ce{H_2O}$ etc.) show the number of molecules required to produce glucose ($\ce{C_6H_{12}O_6}$), so this is incorrect.

Answer:

C. It does not show that photosynthesis consists of many separate steps.
