Why 12H2O shown in equation not 6H2O ?

1.	Why 12H2O shown in equation not 6H2O ?
Answer» Because it has been already proved that oxygen evolved during photosynthesis comes from H₂O not from CO₂. In case if 6H₂O is used then 6O₂ will not be released (only 3O₂ is produced). So, 12H₂O produces 6O₂ and out of 12H₂ molecules 6H₂ is used in making of glucose and rest 6H₂ with oxygen of CO₂ form 6H₂O as product.

Because it has been already proved that oxygen evolved during photosynthesis comes from H₂O not from CO₂.

In case if 6H₂O is used then 6O₂ will not be released (only 3O₂ is produced).

So, 12H₂O produces 6O₂ and out of 12H₂ molecules 6H₂ is used in making of glucose and rest 6H₂ with oxygen of CO₂ form 6H₂O as product.
