what type of reaction is this

Question

Li + H2O --> LiOH

A. Combination
B. Combustion
C. Decomposition

Im thinking combination but the H2 is confusing me

Answer 1

You didn't write all of the equation. You don't have a H2 in the equation but you should have it there.
2Li + 2H2O ==> 2LiOH + H2

I don't like any of the choices. The reaction is a single replacement. The Li replaced H in H2O. Sometimes I see it called single displacement.
