-More on Limiting Reactants | Wikipedia-
"The limiting reagent (or limiting reactant) in a chemical reaction is the substance that is totally consumed when the chemical reaction is complete. The amount of product formed is limited by this reagent, since the reaction cannot continue without it. If one or more other reagents are present in excess of the quantities required to react with the limiting reagent, they are described as excess reagents or excess reactants.
The limiting reagent must be identified in order to calculate the percentage yield of a reaction, since the theoretical yield is defined as the amount of product obtained when the limiting reagent reacts completely. Given the balanced chemical equation, which describes the reaction, there are several equivalent ways to identify the limiting reagent and evaluate the excess quantities of other reagents."

GREAT! last 8-10 minutes GREAT examples of HOW-TO problems in limiting, especially using stoichiometry, first half is great if this is your first exposure to limiting. Thanks-- SUBSCRIBED!! Great chanel, thanks for your time!
Once again, Professor, THANK YOU SO MUCH FOR THIS ONE-- you really are an angel to help students like me :-)
THANK YOU SO MUCH FOR THIS VIDEO. I'm so happy I can now solve stoich problems! :)
Thank you bro.. it really helped a lot.. I can understand ur teachings easily.... u have great teaching skills ..
I rarely comment on any videos but this video REALLY helped me. I've watched tons of chem vids about stoichiometry but when our unit exam came, I cried in the middle of solving cus the questions were unfamiliar and was not discussed in other videos. It was broken down and discussed here and now I understand stoichiometry. A million thanks!
😊 Glad to help!!
amazingly thorough and perfectly explained. Thank you very much!!
Love this video! Thanks so much!! Very thorough, and I now thoroughly understand limiting. I am going to get an A on the test, thanks to this and your stoich vid. THANKS!!
Great teacher u r
Super great job at explaining
THANK YOU YOU'RE AWESOME OMGGG FOR REALS
thank you,dear sir :) subscribed
Thank you sir
You're welcome!
Salami sandwiches for the win
without converting from mass to mole is there any direct method to find without conversion
Suppose 316.0 g aluminum sulfide reacts with 493.0 g of water in a double replacement reaction. What mass of hydrogen sulfide is produced? Assume reaction is 71.2% efficient. HELP ME
The reaction produces aqueous aluminum hydroxide and hydrogen sulfide gas, so from there you should be able to get the coefficients and solve for amount of product expected.
First!
