Introduction to Limiting Reactant and Excess Reactant

Published on September 17, 2015 by

Limiting reactant is also called limiting reagent. The limiting reactant or limiting reagent is the first reactant to get used up in a chemical reaction. Once the limiting reactant or limiting reagent gets used up, the reaction has to stop and cannot continue. After the limiting reactant or limiting reagent is used up and the reaction stops, there is extra of the other reactants left over. Those are called the excess reactants. In this video, we'll first learn about limiting reactant and limiting reagent by comparing chemical reactions to cooking recipes. We'll look at how to calculate limiting reactant and limiting reagent using cooking ingredients, and then looking at an actual stoichiometry problem,

    My chemistry professor has a PhD but he is the absolute WORST at teaching. He means well, but God, is he awful at presenting in front of a class of 15 students. Stuttering, weird sounding sentences that don’t make sense in his powerpoint lectures, and over complicating every little thing leaving us all confused. Can’t believe I’m paying for this bullshit.

    was produced rather than the relatively inert
    B2O3 was a factor in the discontinuation of

    Your videos are great! I’ve been using them during the covid distance learning situation.

    One thing I wish this video had was the use of conversion factors when solving the cheeseburger problem. I like that you did it first by reasoning it out. I think it would have been helpful to do a second cheeseburger problem, but this time with conversion factors. I think that would have been helpful to do before the chemistry problem.
