In photosynthesis, carbon dioxide is reduced and h2o is oxidized. What type of chemical reaction is this?.
Vilka [71]

In photosynthesis, carbon dioxide is reduced and H₂O is oxidized. The type of chemical reaction is an oxidation-reduction reaction.

<h3 />

Explanation

Oxidation-reduction reaction are reactions that take place in electrochemical processes. Reduction is the reaction of decreasing oxidation number and increasing electrons and it can be said that reduction is the reaction of a substance losing oxygen. Oxidation is the reaction of increasing the oxidation number and decreasing electrons and can be said that oxidation is a reaction where the reaction of a substance binds oxygen.

Photosynthesis is one type of oxidation-reduction reaction that occurs naturally in everyday life. Photosynthesis has a complex process and involves green plants and certain bacteria. In the event of photosynthesis, carbon dioxide is reduced to carbohydrates and water is oxidized to oxygen.

The oxidation-reduction reaction in photosynthesis is:

6CO₂(g) + 6H₂O(l) + energy --> C₆H₁₂O₆(aq) + 6O₂(g)
