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!

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

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

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

great way to explain it. finally understand thank you

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

best one i’ve found! thank you!

Thank you for this lesson

You explained it perfectly omg

Thank you this has really helped me

Hi sir.can u do a lecture on ionic equilibrium

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

Beautiful video!

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

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

Thank you!

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

Thank your for your help

Thank you Sir

sorry might be too late but that's the molar mass of si3n4, thats how you convert moles to grams

the dave grohl of chemistry

you're the best

well since i did not get the mark i wanted in chem i have to redo grade 12 U chem :( this will be useful again i guess.

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

I dont udnerstand how you got 0.0804 mol Si.

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.

N is 14, so N2 is 28

Awesome sir !!

👍👍👍 very nice

Literally studying for my final the morning before 💀💀

how did you get the actual yield

It is given in the question

How are you find the Actual Yield????

@ProfessorDaveExplains

By doing the experiment and weighing the product.

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