Practice Problem: Limiting Reagent and Percent Yield

Once we get the hang of stoichiometric calculations, we get a curve ball. Limiting reagents? Not all of the reactants will react? We might not get as much product as we expect? Let's practice identifying the limiting reagent, calculating theoretical yield, and percent yield.

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

I can't express how pertinent your lessons are to my COVID college learning. For Chem and Calc...Thank you

[circlefont]

I cannot begin to explain how big of a help this was. THANK YOU SO MUCH 🙏🙏🙏

[farhanalam]

You are a brilliant teacher of basic concepts. Some other videos I have seen is just focusing on the units and did not go over what these ratios mean. Thanks!

Hey Professor Dave, can you make a playlist with all tutorials and all practice problems combined?

[assadaaadinawa]

understood better than my chemistry master. you are my life savoir.

[robertstanley]

Thank you! 2 hours later, I solved how the answer was received. Many thanks! Just subscribed!

What if there are two products? How would the second method work?

[dalianycamacho]

great way to explain it. finally understand thank you

[cameronholloway]

i had passed my exam with really high marks thanks keep up the great work =D

[krishnaswamy]

I think you really explained this concept really well. Thanks a lot! But I am confident on how you got 2.89g?

[davinderarora]

Best practice video ever!!!, thanks a lot!

Hi sir.can u do a lecture on ionic equilibrium

[mjxstte]

oh my gosh thank you so so much, you saved my day!! 😭

[jothamwainmut]

Thank you very much😁
I'm certain that I will pass my test tomorrow 😌

big question: why did you multiply the 0.0712 by 2/3? O just need some help with that.

[Nour-Abou-Noweir]

How is the silicon the limiting reagent ?! It has a larger no.of moles than Nitrogen in both
5:10

[sasrutha]

Bro in this how did you divide N2 with a molar mass of 28 that’s the sulfur mr rite??im talking about the first question.

[hex]

Where did you get the 2.89g at the end?? 8:37

[coss]

7:30 where did the 140.28 came from Im so confused please help.

[jeev]

I dont udnerstand how you got 0.0804 mol Si.
