Answer 1

Answer1: Photosynthesis equation

6CO2 + 6H2O + Sunlight--------------> C6H12O6 + 6O2

Answer2: A Photosystem-II set of reaction is measured from this experiment.

In photosynthesis, the oxygen is released through the breakdown of H2O in the presence of sunlight

Answer3: Other molecules are necessary for the photosynthesis are: CO2, H2O, Chlorophyll and sunlight

Answer4: Sodium bicarbonate (Na2HCO3) was used to prove CO2 is essential for photosynthesis. In water normally the CO2 concentration is very low. So sodium bicarbonate (Na2HCO3) breaks into CO2 and H2O.

                        2 Na2HCO3---------> Na2CO3 + H2O + CO2
