Photosynthesis is the reaction by which green plants convert water and carbon dioxide into glucose and oxygen using sunlight (radiant energy). The chemical equation for photosynthesis is below.

6CO2 + 6H2O + sunlight energy ——> C6H1206 + 602

What evidence can you provide that shows photosynthesis is an endothermic reaction?

Photosynthesis is considered an endothermic reaction, because during the process of photosynthesis, energy from the sun or sunlight is being absorbed.

Explanation:

Any chemical reactions that absorb heat energy from the surroundings to form products is termed the endothermic reaction.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

your answer would be “dry”
