Limiting Reagents and Percent Yield

Chemistry doesn't always work perfectly, silly. Molecules are left over when one thing runs out! Also we never get all of the products that we thought we might by doing the math. You gotta know about the limiting reagents and the percent yield! Don't worry, it's as easy as bologna sandwiches.

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

professor dave whippin out the bologna sandwich analogy makes him my favorite person ever

[FaizaF]

Came here from Khan Academy. Much clearer presentation than the current Khan Academy video on limiting reagents. Thank you so much!

I always knew Jesus saves, but I didn't think he'd be saving my Chemistry grade

First thing we need to do is convert to moles because “MASS doesn’t tell us ANYTHING “ thank I needed to hear this

[aneesonhisknees]

personally you deserve more subscribers and people need to see this.

[AryanSharma-khzw]

I love you professor Dave, you know all about the science stuff and you made everything as easy as a piece of bologna sandwich ☺

[HyacinthChynthia]

Limiting Reagents and Percent Yield are one of the most confusing topics for me in Chemistry. Thanks to you, I understand it better. This is really helpful for students like me. Thank you very much!

[Rieleyhunt]

1 week of not understanding class into 4 minute video. thank you chemistry jesus

[rafyraffee]

THIS IS AN AWESOME CHANNEL!! Please for the love of god don't stop making these videos! I need this so I don't fail chemistry!!!

[sarahotto]

Thank you so much! I wasted so much time on Kahn Academy confused as all hell, and you summed it up perfectly in less than 5 minutes!

[joelherring]

Thank you Professor Dave for explaining this so well, I've got a final in a few days and need someone to actually teach me well. YOU ARE THAT MAN

[Pinkpanther]

I was here for my retake for a chemistry test, and I fell in love with these videos! Thank you professor Dave

[electromc]

This is perfect for studying for my grade 11 chemistry exam. Thank you Professor Dave!

[maazkazi]

literally speaking, i just stumbled across this channel looking for revisions before mah test but i was bowled over by the content and clarity of the video. u literally have earned a new subscriber... :)

[castingashadow]

Thanks to this video, I am seeing some light. The graphics add a transitioning touch to the relationships of the numbers we just can't quite see with erase markers. You are making a great difference.

[baekhoyangi]

You made this sound easier to grasp. I hope it helps when I explain this during my teaching demonstration on Friday. I'll be back for an update (if I got the job or not lol). Thanks Professor Dave!

الكاشف : هو الذي ينفد اولًا بالتفاعل .
الفائض : هو الذي تبقى منه كميات زائدة بعد انتهاء الكاشف .
لكي تستخرج المول بدون تعب :
لكل عنصر او مركب معادلته ، خذ القانون :
غرام العنصر • واحد مول / المستخرج من غرام العنصر .
الكتلة المولية قبل التفاعل • واحد مول / العدد الذي بجانب الصيغة .
بعد هذه التفاعلات الاقل هو الكاشف والأكثر هو الفائض . بعيدًا عن العدد المضروبة به الصيغة .
لا تستخدم الكاشف للمعادلة التالية ان شاء الله لأنه سيظهر الناتج خطأ .
الظاهر الاخير • العدد بجانب الصيغة الظاهرة بعد التفاعل / العدد بجانب الصيغة قبل التفاعل • المستخرج غرام / العدد بجانب الصيغة بعد التفاعل .
هذه هي المعادلة المذكورة ‏‪2:35‬‏ هنا في هذه الدقيقة والثانية .

For the Question at 4:00 . Can you please quickly tell me how many moles of CH3OH will react in this rxn?

[bigpotato]

Thank you for teaching me in 4 minutes what my teacher could not teach for the past few months

[poorna]

Indeed your way of teaching is extremely easy to understand you actually deserve 10m or even more than that
