I understood this lecture
It is based on previous lecture
Eq.wt of H2SO4 is 98 or 49 I am confused 😕
@@poojasahu7831 obviously 49
😅.
98 to GRAM Molecular mass (GMM) hain and 49 hain equivalent weight .
Eq.Wt=GMM/n
n =valence factor.
For H2SO4 it is 2 I.e no of ionisable hydrogen ion
So Eq Wt=98/2 =49.
HOPE samaj aaya hoga:)))
Sir I cannot understand
Sir at 34.22 eq.wt of crystalline oxalic acid is 63 not 63.5
Same confusion 🤔😑
Ya that was a mistake, it is 63. Sometimes small mistakes happens while teaching .
Sir charge no. Kese nikal te h
This lecture is very doubtful
Yes

Today's last lecture
Redox bina padhaye solutions pe bhj diya
It's Focus batch ......mainly for Repeaters so teacher expects some basic foundation of Concepts.
Regular batch sequence is different
@@BiomentorsClassesOnline we lack basics in many concept
That's y we couldn't clear
We don't understand many things and mug up that's y we r repeating
There must be some fault some problem in our knowledge and concepts which made us not clear
If we skip things would we be able to clear this time?
There are few chapters in physics and chemistry which i know nothing of like polymers in chemistry and magnetism and alternating current
I have even skipped questions from those
In my coaching last year they didn't finished the syllabus due to curfew and lockdown and they took lots of time to complete very few chapters
So my concepts are not clear
And we have to attend focus batch's lecture of 8 hours and then self study if i start doing basic lectures of other chapters the time for self study will become more less
Why can't we follow the ncert trend and do chapters as they are assigned in the book?
Why randomly from here and there?
Don't mind sir just asking
@@BiomentorsClassesOnline and one more thing sir
If you check the comments of other students they commented 3-4 months back
They also weren't taught?
Just asking
Hey m from focus batch too
See there's a sequence of chapters
If u follow that, ull have no issues in understanding the syllabus
Jus for ur info,
physical chem is best understood when this following sequence is followed:
Periodic table + Atomic structure
Chemical bonding
Basic concepts of chemistry
Solutions
Redox
Electro
Surface chemistry
Kinetics
Equilibrium
States of matter
Thermodynamics
Solid state
& in focus batch schedule,
Jus one thing was that they took solutions first instead of basic concepts of chemistry
That's y I saw basic concepts of chemistry ke all lects in 2 days first
& Then now I'm doing solutions
But they've designed solutions 2021 lectures in such a way that basic concepts of chemistry is also intricately explained
So *it doesn't matter* if u do solutions before or after basic concepts of chemistry chapter
This was the only thing that was aage peeche in focus batch flow
Baaki all is properly charted out so that syllabus is understandable & not heavy on Commandos
