Limiting reagents

[Hanniel U 2B]

I watched the video but I'm still not sure. Can a chemical equation have two limiting reagents ?

[Matthew D 3F]

A two step chemical reaction can have two limiting reactants, one for each step, but a single step chemical reaction can only have one limiting reactant.

[Jessica Helfond 2F]

A one step chemical reaction can only have one limiting reagent because (as long as the 2 reactants are present in different amounts and/or you need different amounts for the reaction) you will run out of one first. Therefore, the reaction will not be able to continue because you will be out of one of the reactants you need for the reaction. The one you run out of is the limiting reactant, while you still have some of the other reactant left over.

Is it possible that two reagents get used up at the same time so that an equation can have two limiting reactants?

[Reese - Dis 1G]

You can only have one limiting reactant because it limits what product can be produced, so it is not possible to have more than one.

The limiting reagent is the reactant that gets used up first in a chemical reaction. It determines how much product is produced. There cannot be two limiting reagents because once one reactant is used up the reaction cannot continue.

[Hanniel U 2B]

Okay but during the post assessment, I answered that it cannot have two limiting reactants but the answer was wrong. That's why I'm confused.

There is only one limiting reactant in a single step chemical reaction. If the moles are the same for all reactants none of them are limiting the others' potential to create more product. Thus, there is a perfect amount of reactant to fully react with the others in order to form product.

There cannot be two limiting reactants, because only one can do the limiting to the other. However, there can be no limiting reactants in which the mole ratio for the reactants are equal.

In one step-reactions, there will only be one limiting reactant. It is possible that all the substance involved in a reaction is completely consumed, in which there are no limiting reagents or all the reactants are limiting.

[LG2019]

There cannot be more than one limiting reactant. There is no limiting reactant if both substances are completely used up.

[Grace Diaz 3F]

There can only be one limiting reagent in a reaction. Since the limiting reagent determines the amount of product that can be created, once it has been used it would not make sense that another reactant could limit an already determined product.

[Ronald Thompson 1F]

Yes there can be more than one depending on each step of the reaction
