Explain photosynthesis and write its balanced chemical equation.

here are the answers to question 3(a) and 3(b):

a) Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, in the form of glucose. This process uses carbon dioxide and water as raw materials, with oxygen as a byproduct.

b) The balanced chemical equation for photosynthesis is:

$$6\text{CO}_2(\text{g}) + 6\text{H}_2\text{O}(\text{l}) \xrightarrow{\text{light energy}} \text{C}_6\text{H}_{12}\text{O}_6(\text{aq}) + 6\text{O}_2(\text{g})$$

Where:

• $\text{CO}_2$ is carbon dioxide
• $\text{H}_2\text{O}$ is water
• $\text{C}_6\text{H}_{12}\text{O}_6$ is glucose (sugar)
• $\text{O}_2$ is oxygen
