44:40 Hydrogen is not balanced
pls edit so that others dont get wrong info

[rgenrg]

Sir, this was a very good way for me to practice, but u have made a mistake in q9. U didnt make the eqn balanced. H2 was supposed to be 2h2 but u just wrote it as h2. Hope you see this ❤. Thnx a lot sir

[kviewsindays]

44:00 here the balanced rxn would be :
2H²+O²--> 2H²O
Btw the session was amazing
