Final answer:
In the chemical equation for photosynthesis, the reactant state is gaseous for carbon dioxide (CO₂) and liquid for water (H₂O). The product state is solid for glucose (C₆H₁₂O₆) and gaseous for oxygen (O₂).
Step-by-step explanation:
The student asked about the state for each substance in the chemical equation of photosynthesis. The chemical equation of photosynthesis is 6CO₂ (g) + 6H₂O (l) → C₆H₁₂O₆ (s) + 6O₂ (g).
In this equation, the states of the substances involved are indicated as follows: carbon dioxide (CO₂) and oxygen (O₂) are gases (g), water (H₂O) is a liquid (l), and glucose (C₆H₁₂O₆) is a solid (s).
These states are important for a balanced chemical equation, which not only includes the molecular formulas of the reactants and products but also their physical states.
