002:
CO2 + H2O----> Carbohydrate + O2
Yes, we know it is true.
But how do you perform an experiment to show that the above equation is true (water is required)?
And the answer is impossible to perform an experiment.
This question must be placed in Biology to have better answer . Since here I try my best to answer :
Photosynthesis can be represented by : CO2 + H2O---->Carbonhydrate + O2 This happens in the leaves with the chlorophyll with the sunlight light as the energy for building up the food . This process has been verified true so it is a fact ! According to the above equation , water must be required to provide the Hydroen element in the carbonhydrate (C6H22O11)n . From this equation already prove water must be present to make the photosynthesis complete . Moreover without water , not to mention no photosynthesis , all plant will die !!! If you want detail procedures of this test , go to ask in BIOLOGY .
