Why water, of course, just through in the electrons needed.
Plants hydrogenate it into sugars. The hydrogen comes from water and oxygen is given off as a waste product.
Given the energetics presented above, there is a strong thermochemical bias for the production of water over hydrogen peroxide when H2 and O2 are reacted together.
When water splits, hydrogen gas and oxygen gas are formed.
There isn't a chemical process that separates oxygen and hydrogen in water. To split the water into hydrogen and oxygen you need to perform electrolysis on pure water. Hydrogen gas will be given off at the cathode (- end) and oxygen will be given off at the anion (+ end)
oxygen
Oxygen.
Oxygen.
Oxygen (O2)
The gas given off as a waste product of photosynthesis is oxygen. Glucose is also made during photosynthesis. These products are made from carbon dioxide and water.
Hydrogen
Yes, oxygen is released as a product of photosynthesis.
During the burning process, oxygen combines with carbon to produce carbon dioxide.
