Step1: Recall photosynthesis reactants and products

Photosynthesis uses carbon - dioxide, water and light to produce glucose and oxygen.

Step2: Write the chemical equation

The chemical equation is (6CO_{2}+6H_{2}O\xrightarrow{light\ energy}C_{6}H_{12}O_{6}+6O_{2})

Answer:

(6CO_{2}+6H_{2}O\xrightarrow{light\ energy}C_{6}H_{12}O_{6}+6O_{2})
