potassium metal reacts with water to give potassium hydroxide and hydrogen gas
=> 2K + 2H2O --> 2KOH + H2 is the correct answer as I searched.
doesn't it should be K + 2H2O --> K(OH)2 + H2?
Please clarify my doubt, I will mark brainliest to who help me.

It's all about valency K belongs to first group means 1 Valence electron on the other hand OH has also valency of 1 hence the atoms remains unchanged , the now you have to balance the moles as to follow law of conservation of mass , due to which we have to add 2 on KOH so the equation became right
luciferxixo:
why not K(OH)2?
For K(OH)2 we should have the valency of K -2
for example Mg has Valency of 2 it can form Mg(OH)2

THE BALANCED CHEMICAL EQUATION FOR THIS REACTION WOULD BE-
2K + 2H2O --------------->2K[OH] + H2
