I think it will be B. Hope it helps :)
First we must write a balanced chemical equation for this reaction

The mole ratio for the reaction between
and
is 1:2. This means 1 moles of
will neutralize 2 moles
. Now we find the moles of each reactant based on the mass and molar mass.



The
was enough to neutralize the acid because 18.87:39.67 is the same as 1:2 mol ratio.
You have to switch the elements based in if they're metals/nonmetals. so nonmetals switch with each other and metals switch with each other.
