[@DelijaZauvjek20]

Delta H for equation 3 after being switched is 888 :) Great video, thx! :)

[@MichelvanBiezen]

You are correct! Good catch!!

[@bosheben2081]

Man you are amazing, i have exam today and you save me, thinks 🍓🍓🍓

[@MichelvanBiezen]

All the best on your exam.

[@brooksideforest1107]

Got a slighty different result: -1249kj

[@fairlight3193]

he made a mistake i got that too

[@ahmet27382]

Yes, in 3rd equation ∆H should have been +888kj.

[@petereziagor4604]

Looking at it before watching Swap equation 1 Multiply equation 3 by 3 then swap Add everything and we're cool

[@MichelvanBiezen]

Good insight.

[@hyderali692]

Sir , Sir, cancelling 3 with 3/2 gives 3/2 what is the algebraic method behind that?

[@MichelvanBiezen]

Sorry, I didn't understand your question.

[@ahmet27382]

It's not cancelling, he just did subtract 3/2 from 3.

[@hyderali692]

Ok.. Sorry I still dont understand I am extremely weak in mathematics

[@tubayazdani745]

I don't think its correct solution
