7.2.5: The Haber and Contact Processes
interesting! thank you for the best explanation!
I appreciate
r=m.v/B.q
So do the 85 and 87 isotopes of the rubidium sample exist in the same sample simultaneously?
Measurement in the form of Specific Gravity (SG).
THANKKKKKKKK YOUUUUUUU OMFG
I LOVE U SM OMGGG FINALLY I UNDERSTOOD IT
Excellent explanation
Are these videos created for a IB school?
Yes, yes they were.
How in the fk RUclips recommended me this I was searching for November nutter
😂
Thank you sir
Great Video !!!
Thanks! It helped me with my homework
Very Helpful! Any other ILC users watching this video?
tq so much sir I understood this topic
Thank you, super informative!
nice
This is the best and simplest explanation of all time. Thank you so much!!!
Really oooh an easy explanation of such a complicated thing more videos pliz
My chemistry teacher told me to watch this the school system is broken
He told you that because children have different ways to learn. Maybe you learned better from this video
Your teacher lead you to knowledge. Doesn't seem broken
you are the best mete
What da dog doing 😻
nice videooo
Great video💯
FINALLY someone who explained it simply, thank you!
Legend Thank you Sir.
It is the arrow part for me, kinda funny. Nice video
So these strong acids are just based on memorization? Is there no way to compare acidity strength with nothing but the elements themselves?
9 years later and I am still watching this. Legendary.
Wow this is an amazing explanation
it is understandable
Holy cow this explanation actually made sense. Thank you!
U SAVED MY LIFE, GOD BLESS U
This is IB chemistry oh lord im so thankful
This is the best and simplest explanation of all time. Thank you so much!!!
Great
Who all are watching in covid 19
Okay now we can build a mass spectrometer at home and cause a Resonance Cascade lol.
Multiple errors in this video including the measurement reading and the scientific notation. Great video but the errors are confusing to students. Too bad.
Thank you for your comment! You're right. For clarity, allow me to make explicit what errors I see now (eight years later). 1) [At about 2:17] The pictured digital scale reads 0.0, while the text and audio have "10.5g". 2) [At about 3:08] While the number of significant figures labeled for each variation is correct, I should have left the exponent unchanged because in the audio I talk about writing "...the same value...in different ways." As it stands, the scientific notations represent the integer values 450,000, then 45,000, then 4,500, then 450, and finally 45-though with increasing numbers of significant figures, as noted. In addition to getting the audio description and visual examples to agree, I see now I should have added a column with the values expressed in plain integers with ± values to further illustrate how scientific notation is used to communicate significant figures. Please let me know if you see other errors.
Im here because im studying this in my college. Wish me luck guys
Who all watching from 2020
How to know which acid disassociates completely Plz reply sir....It is my biggest doubt
finally a good explanation
Bugga
dude same
Thank you
thank you so much, you made it so easy for me to start my topic!!!!!
thank you
