Question

Photosynthesis is a chemical reaction where carbon dioxide and water react to form glucose (C6H12O6) and oxygen gas. Which represents the proper balanced equations for photosynthesis? A) C6H12O6 + O2 → CO2 + H20 B) CO2 + H20 → C6H12O6 + O2 C) C6H12O6 + 6O2 → 6CO2 + 6H20 D) 6CO2 + 6H20 → C6H12O6 + 6O2

Answer 1

Correct Answer: D) 6CO2 + 6H20 → C6H12O6 + 6O2

The reactants are Carbon Dioxide (CO2) and Water (H2O) and the products are Glucose (C6H12O6) and Oxygen gas (O2).

In a balanced chemical equation, the number of atoms of each element are same on both left and right hand side of the equation. 

In the given options, option D gives the balanced chemical equation and mentions the reactants and products on correct sides of the equation. So the correct answer is Option D

Answer 2

6CO2 + 6H2O --> C6H12O6 + 6O2  so D is the correct answer.
