Past exam question of chemical equilibrium

When they are talking about a blessing they were referring to you 😇😇 your videos are really helpful 👌 . To actually think that i have been struggling with maths and science until you came . I would like to take this moment and Thank you for your help 😇😊😊

To the person reading this:Even though I don't know you, I wish you the best of what life has to offer❤

As a class of 2022 we have to make Mlungisi Nkosi trend in January because wow 🔥 👌

Mr Mlu your the best sir..YOU UNMATCHED I pray God blesses you

great video, just what I needed😄but how is it 0.81 for the number of moles reacted for Iodine🤔I got 0, 081

[zinhlethwala]

And how is it to get 0.81 when we divide 0.162 by 2 instead of 0.081 ..
I think there's a mistake there sir

[Chioma]

Hey sir there might have been a mistake with the change in concentration in 6.2 but the steps to finding the answer really helped... Thank you so much...🙌🏽😩♥️

Hi sir I have a question about KC


So there's a question I once saw I'm not sure was it sup or what so they gave us the statement and the equilibrium so the question was to calculate I think the initial moles of a certain company and obviously the KC value it's the same because they didn't change the temperature

The question was calculate the initial moles if the equilibrium was re-instated so my question is how do I use the given information of the initial KC to calculate the re-instated equilibrium

[pabalelomasha]

good evening sir hope you well. quick question sir how is the forward reaction endothermic if it was decreased

[buyile_beverly]

Sir do you have a video on *REACTION RATE* graphs with regards to Le Chatelier's principles and not the chemical change ones

[lehlohonolokhakhane]

Mr Nkosi canyou please do question 7 up to question 9 for chemistry paper 2..that we just written today please sir .. your videos do really help.. which I appreciate sir.

[Sandiso]

Mr you you see to have made a mistake with the KC calculation the moles for I2 were 0.081 not 0.81

[zinhlethwala]

How it is possible sir to get 0.162 on change in mold of 2HI while we started with zero
Wasn't is supposed to be 0-0, 162 then we get -0, 162 so that when we check by adding equilibrium and change in Mol we can get zero ..please assist there I'm getting confused
