The reaction K(s) + 2H2O(l) → 2KOH(aq) + H2(g) is a decomposition reaction. True or false

False

Explanation:

Decomposition reaction is a reaction involving the break down of a single larger chemical species into two or more smaller species. ones. The above reaction is not a decomposition reaction rather, it is a single displacement reaction as K displaces H from water to form KOH liberating H2
