How are the reactants represented in the chemical equation for photosynthesis?
© 6co2 + o2
6co2 + 6h20
o coh12o6 + 602
o c6h12o6 + 6h20

The reactants are represented in photosynthesis equation as follows:

6CO2 + 6H20 --> C6H12O6 + 6O2

Explanation:

During photosynthesis, six molecules of Carbondioxide (6CO2) reacts without six molecules of water (6H2O) to form six molecules of oxygen (6O2) and a molecule of glucose (C6H12O6).

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.
