No, during the light reactions. Photolysis splits the water molecule at Photosystem II.
false :)
Endothermic reactions are reactions which absorb heat rather than exothermic reactions which emit heat. Consider the example of carbonated water, as it has CO2 dissolved it's in form of carbonic acid and it splits. H2CO3 -> H2O + CO2 In this reaction heat is absorbed.
In nuclear fission it is the nucleus of the atom that splits, not a molecule, and this releases neutrons and energy. Reactions at the molecule level are termed chemical reactions, not nuclear, and these chemical reactions involve whole atoms and molecules.
Nuclear Fission
It is a reaction that has only one reactant and multiple products. Meaning one chemical decomposes/splits to form others. H2O2 > H2 + O2.
Photosynthesis splits water to liberate O2 and fixes CO2 into sugar.
Decomposition reactions are those in which one reactant splits into two or more products. Only those decomposition reaction are redox reactions in which minimum one of the products is an element.Example-2 H2O ---> 2H2 + O2

h+ ions are released as water splits
FISSION
light reaction and dark reaction
It splits the water molecules into Hyrodgen and Oxygen.
When ballet dancers do the splits in the air it is usually called a spilt leap or a center leap.

Fission.
No, it's a chemical reaction.
Yes, that would be a decomposition reaction.
Depolymerization. Hydrolysis also for certain polymers.
