Mam you are very great teacher you clear concepts very well ठनक्श for teaching mam ❤❤❤

[Doctor_rani]

8:45 ma'am sugar jyada quantity me h but still solvent water hi hoga because sugar water me dissolve hota h water sugar me nhi and water universal solvent bhi hota h jiska dielectric bhi sabse jyada
Hope it helps 🙏🏻 🤞🏻

[oockomk]

Mam please very soon add electrochemistry

[Statusshorts]

There are so many confusion 😢
Please answer mam

[ubrbbjq]

Mam please give one shot lecture of electrochemistry

[noode]

Maine abhi tak Kuch nahi padha hai 😢😢 ab mai chemistry ke is chapter se start kar raha hu 😢.
But by Roshani ma'am lecture I think my syllabus will be Finish 😊😊.
Ma'am please 🥺 give us one shot lecture for backlog
