What do u mean by chemical or physical reaction... Please give me an answer so i can give you the answer.
2 H2O is the chemical formula of two molecules of water, not a reaction.
The chemical reaction is:2 K + I2 = 2 KI
The chemical reaction is:Br2 + 2 K = 2 KBr
The chemical reaction is:2 K + 2 H2O = 2 KOH + H2
probably chemical reaction
A chemical reaction is; when there is a chemical change taking place from energy or shifting of molecular structure.

when the reaction done between solid and liquid interface is called physio-chemical reaction.
The chemical reaction is:Br2 + 2 K = 2 KBr
This is a very fast reaction.
The chemical reaction is:2 K + 2 H2O = 2 KOH + H2
False
Water is not a reaction at all. If you mean to ask if a state change in water is chemical or physical, it is physical.
no reaction
