I am aware that double replacement reactions always have a limiting and an excess. i also know how to find them. However, I just came across a single replacement reaction that asks about the excess reactant. Can someone please explain?

Even double replacement reactions could have both reactants in stoichiometric quantities, that is where neither reactant is in excess. Any chemical reaction between two or more substances can be stoichiometric or have excess and limiting reactants. The excess reactant is the reactant which is left over when the limiting reactant is used up.

the concept is the same, if you drop a small piece of Sodium in a large quantity of water Sodium will react with some water to form sodium hydroxide and a lot of water will still be there so Sodium is the limiting reactant
