Hi sir.. in the balancing question cr2o72-+hno2 gives cr3+ + no3- you told that 7h20-3h20=5h20 that is wrong sir in acidic condition we get 4h20 if we balance so pls clear this out by commenting Original Ans 3HNo2+5h+ + cr2o72- gives 3no3- +2cr3+ +4H20 sir Time in the video: 1hr 47th minute sir... Pls check it and comment it sir ....
class start's at 5:00

Correct bro
45:45
In 1:05:31 oxygen is oxidised and cl is reduced
you are correct
Ans:acitic:Cr2O7²‐ +3So3‐² +8H+_____2Cr+³ +3So4²‐ +4H2o.
Basic:Cr2o7²‐ +3So3²‐ +4H20_______2Cr+³ +3So4²‐ +8OH‐.
Hw1 ans: Cr2O7^²- + 3SO3^²- + 8H^+ + 3H2O → 2Cr^³+ + 3SO4^²- + 4H2O is this correct??..
correct but in reactant no H2O
@@chemicaltrinity7436 ohh... Cr2O7^²- + 3SO3^²- + 8H^ → 2Cr^³ + 3SO4^²- + H2O ... Anish ippo correct thaane.. Hw2 ans: a)5 .. is this correct sir..
Kanyakumari la enga sir . Me too from kanyakumari
yes sir
Is it possible +1 for fluorine
arbitrary value
No bro because of it's high electronegativity positive la oxidation number irukadhu
Yeah only in the case of HOF but in other cases F has -1 oxidation state
No flurine exist in -1 oxidation state only

Talking too much of unwanted things!
No one asked you
Hi sir❤️
Hi
