How many molecules of hydrogen are shown in the reactants and in the products in the photosynthesis equation?

In the photosynthesis equation, which can be summarized as 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂, there are 12 hydrogen atoms in the reactants (from 6 molecules of water, H₂O) and 12 hydrogen atoms in the products (from 1 molecule of glucose, C₆H₁₂O₆). Thus, there are a total of 6 molecules of hydrogen (H₂) in each side when considering the individual hydrogen atoms.
