Even though they have a different formal charge they're still the same chemical right? If we were to some this up to a complete mathematical equation they would both come out to zero. I guess the point I'm trying to make is what use do we get out of a set up like this?
In the first structure, how does the last oxygen have a formal charge of-1? Because it can’t have 7 electrons in the outer shell and the octet rule is not satisfied
Actually, there are elements which are stable despite not obeying the octet rule. That's why the rule is discarded in higher classes, so we study about hybridisation.
It does have 8 electrons in its valence shell (6 lone pair electrons + 1 single bond (2 electrons))so its octet rule is satisfied however it has only 7 of those electrons allocated to it due to the fact that you take 1/2 of bonded electrons so its 6 lone pair electrons + 1 electron from the single pair so its 7.
can anyone help me in this problem ? A driver at 25 m / s detects an obstacle in his lane. Braking starts at a distance of 83 m. At a distance of 23 m, a speed of 13 m / s remains. The speed is expected to decrease steadily. a) What is the absolute value of the acceleration of the car? Give the answer with three significant digits.
You need to use the formula v^2-u^2=2as here, v is 13m/s and u is 25m/s. 'S' is the distance and 'a' is acceleration. Acceleration in this case will have a negative value (retardation) Wait, I just realised that this comment was posted 3yrs ago😅
You are one of the only mathematicians I understand on RUclips. You have truly helped me many times. You have my subscription
lier
Million thanks for making science & maths easy for me and many others.
Regards.
Mesmerizing classes with colorful lessons.
Jazakallahu Khairan.
thank you so much for the help you give everyone, truly appreciate it!
I always find it difficult to memorize this formula, thanks for making it so easy!
very helpful explanation
This is a good video explaining the concept of formal charges. Are there more such examples around?
Really great
Tecnology just like education revolution these days
Hatsoff 🙌

Good Job!!!
This is amazing.
Only I have to say that
Biiiiig thanks
made it laughably easy as compared to the McGraw hill textbooks im paying hundreds of dollars for every semester. Thank you loads
yaaay gooo khan!!!
Saved me!
Great

-3.80 m/s^2, Hope your homework went well three years ago.
Third.
Second
First
Thanks so much for this, it seems like magic to me in class 🥲. Bless up chef
