what type of reaction is this
Li + H2O --> LiOH
Im thinking combination but the H2 is confusing me
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.
