Question

what is the equation for photosynthesis? words + + light, enzymes + +

Explanation:

Step1: Identify reactants and products of photosynthesis

Photosynthesis is a process in plants (and some other organisms) where carbon dioxide ($\ce{CO_2}$) and water ($\ce{H_2O}$) are converted into glucose ($\ce{C_6H_{12}O_6}$) and oxygen ($\ce{O_2}$) using light energy and enzymes.

Step2: Write the word equation

The reactants (on the left side) are Carbon Dioxide and Water. The products (on the right side) are Glucose and Oxygen. The conditions are Light and Enzymes (written above the arrow). So the word equation is:
Carbon Dioxide + Water $\xrightarrow[\text{Light, Enzymes}]{\text{}}$ Glucose + Oxygen

Step3: Write the chemical equation (for completeness, as it's a common way to represent photosynthesis)

The balanced chemical equation is:
$$6\ce{CO_2} + 6\ce{H_2O} \xrightarrow[\text{Light, Chlorophyll (Enzymes-related)}]{\text{}} \ce{C_6H_{12}O_6} + 6\ce{O_2}$$
(Note: Chlorophyll is involved in capturing light, and enzymes facilitate the reactions, so the conditions include light and enzymes/biocatalysts.)

Answer:

Word Equation:

Carbon Dioxide + Water $\xrightarrow[\text{Light, Enzymes}]{\text{}}$ Glucose + Oxygen

Chemical Equation (Balanced):

$$6\ce{CO_2} + 6\ce{H_2O} \xrightarrow[\text{Light, Enzymes}]{\text{}} \ce{C_6H_{12}O_6} + 6\ce{O_2}$$
