I have to say now, a person who explains a topic in the most simple way, like this one, has understood the topic well: like the people in this video. :D My teachers are intelligent too, but since they don't know how to teach a lesson like this, I think you are more intelligent.
Everything nice, yet completely wrong. In the close pot there is a stationary state, not dynamic equilibrium. Continuous boiling is permitted only because the system is open. It would be impossible in a close system (an explosion would occur or boiling would stop if the vessel were hard enough). The boiling pot system is formed of heterogeneous parts (subsystems). Below the cold lid there is no equilibrium, but a neat production of liquid water from condensation process prevailing on evaporation. This is visible to the nake eye just because it is far from equilibrium. In the bottom of the pot the temperature is higher and there is an irreversible process of boiling. This is far from equilibrium too: the number of molecules leaving the liquid is there overwhelming greater than the rate of molecules condensing from vapour to liquid. The overall stationary process is permitted by the existence of high temperature inequalities. You can't have chemical or phase equilibrium without thermal and mechanical equilibrium in a closed system. So you should correct these issues if you don't want students creating misconceptions. Real equilibrium processes (evaporation and surface condensation in a uniform temperature close vessel, without boiling) is showed in the animation only. These processes are invisible in a real system. There you can say that nothing seems to happen while dynamic opposite processes occur at the molecular level.
It is the negative log of Ka - it's useful for calculating buffers to know the pKa of a substance. A pKa indicates the pH where roughly half of the molecules are letting go of their hydrogen.

Greetings to all my fellow Chem 30 peers who have been sent here by their teacher.
So glad we are helping teachers and students all over!

Hi Abigail :) Please go to our website & take a look at our online store! That should help you out :)
Hi there. Please email your question to helpdesk@larnxtra.co.za and we will get one of our teachers to help you...for free!
Mindset Learn in the concentration vs time graph why does the hydrogen concentration decreases at faster level than nitrogen
Superb Presentation mam. Thank you
Best video ever thanks Mam God bless you n your amazing teaching ❤❤❤🙏
Thanks for such a positive comment. Keep at it - Equilibrium can be challenging but it can also be rewarding too!
thank you for all. master teaching mam.
that soup looks disgusting
This was brilliant, thank you so much !!!
Thanks mam this is the best method to explain.
this is violently early 2000's
IKR?!
Tnak u so mush it is help full
So glad to be of assistance.
Please make video on phase rule
My teacher sent me to this video 😄
nice and easy to understand
This is Grade 7?
Excelente aula, parabéns!
This is very helpful. Thank you!
Hello fellow shsg students
fantastic!
how can i get this video for my class. reply
very nice
nice and easy to understand
nice idea to explain
helpful..
Thanks
so,what is pKa????please!
It is the negative log of Ka - it's useful for calculating buffers to know the pKa of a substance. A pKa indicates the pH where roughly half of the molecules are letting go of their hydrogen.
