Stoichiometry BCA

This is an intro of how to use a BCA table for Stoichiometry

Even though this was posted a while ago, I just want to thank you for this video. It was extremely helpful given the way you taught it compared to how my teacher did. Thank you! I understand my homework now!!

Thank you very much, my teacher can not explain as good as you do. You helped me out a lot.

Helpful stuff. Didn't see it mentioned elsewhere how the coefficients affect the numbers below

[indigo]

you are literally a life savor. thank you so much

[microwaved.orange]

Thank u for teaching me what my chem teacher OBVIOUSLY can't

[isaacjackson]

Thank you so much, this helped me pass my test!

THANK YOU, YOU'RE A SAINT AND YOU SAVED MY GRADE <3

[amerigurley]

Thank you! I have now learned enough stoichiometry to help out my sophomore with his chem. homework. :D

Thanks g homies like you always savin me on exams, ill make sure to write you that cut of my paycheck when i get a job 💀

[rose_brier]

This helped me better than my teacher.

seems pretty weird to call the little calculations of the moles the "factor label" method when there are NO units in the calculation

[paulfar]

wouldn't the inclusion of the units make it completely clear that the stoichiometry was done correctly?

[ishmamsrabon]

Faster way is to notice molar ratio then times by 13.6, no need to do a whole bca

Too many information are being given live. I am not sure students can follow all the steps, especially because you use different symbols. Obviously the can rewind but it's important to imagine them having not all the time you'd like them to have.

Also, a student can easily focus on other information during your presentation such as:
- Why do you write "xs" for H2 and "?" for O2?
- Why do you put a minus and is it obligatory?
- Why "xs-13.6 = xs"?
- Why do you write 6.80 instead of 6.8? (you're adding a digit)
- Why is there an x under the first xs? (you're multiplying so use preferably · )
- Dioxygen instead of oxygen can also make it hard for some.
- Why do you multiply by 1/2 and not 2/1? (Hard for some to use the ratios)

6:55 Please do not let these small details happen. Otherwise the students may do the same and worst case scenario may just have misconceptions of what units they should use.

As a physics teacher, I like how you present it. But there are too many hidden steps that should be more explicit for students to understand it. The video is 6 y.o. Maybe you have already improved your YouTube skills so congrats!

Thank you so much for posting this. It really helped me to better understand the concepts we’re learning right now in AP Chem and I have a big test in a couple days. 🩷
