During the light reaction, a molecule of water is split apart. explain what happens to each of the following: a. electrons
b. hydrogen ions
c. oxygen atom

Water is split apart through a process called photolysis

H2O--->1/2O2+2H+ +2e-

a.The electrons enter the electron transport chain they pass through different molecules that are reduced and then oxidized and end up in NADPH

b.The hydrogen ions build up in the thylakoid and end up passing through the ATP-synthase for this reaction to occur(ADP+H3PO4-->ATP+H2O)

c.The oxygen atom binds with another oxygen atom to form an oxygen molecule and is released in the atmosphere.

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.
