Two limiting reactants?

Can a reaction have two limiting reactants?

I feel like there should always be an excess of one reactant which in return will cause the other reactant to become limited, so no I don't think its possible. A real-life example would be eating a bowl of cereal where you might put more milk than cereal and in the end, the bowl would be left with milk(excess reactant) and no cereal(limiting reactant). Hope this helps.

No, because if there were multiple limiting reactants, there would be no excess products.

Two reactants cannot limit each other. You can have both reactants be used up completely in equal ratios.

No, but two reactants can be used up in equal amounts. Neither of them limits the other.

No, they will either both be completely used up or only one will be in shortage

No there could not be two limiting reactants as there has to be one which will run out and another in which we will have an excess of there can not be two limiting.

So is the overall fact that there can't be two limiting reactants because only one reactant will be completely used and the other will be in excess? Multiple reactants cant be used up in a single reaction?

No because it was either be completely used up or some left over and two reactants cannot limit one another

You can have tow limiting reactants, but only if when both run out at the same time, meaning they both hit 0 amount left as soon as these reactants are reacted away with available reactants.

However, the case where there are two limiting reactants is pretty rare - most chemistry problems will result in only one limiting reactant. (It also doesn't happen often in real life, because experiments usually put one reactant in excess.)
