thank you malume. i wholeheartedly believe that the good Lord redirected me to this channel . i wrote my mid-june chemistry exam today and i felt very prepared and confident throughout the whole exam as i knew how to tackle every problem i came across because of your video lessons,i am most certainly sure that i attained a distinction for that exam .i am truly grateful!!
Thank you Mr Nkosi !! I went from a average of 43% in my Chem tests to getting one 93% for my organic chemistry test ! I really appreciate everything it's super helpful and you made me enjoy and understand physics and chem alot more 🎊

Sir you are a walking and a talking text book, thank you so much for this, I did my matric 10 years ago, I decided to upgrade my maths and physics this year so balancing work and school was a challenge so luckily few weeks ago I bumped into one of your videos , they helped me a lot . Hoping to do better this time if not I will write again in June coz now I know you are here.
Mr Nkosi is such great help . Sometimes when i do not understand any topic in class i just know that Mr Nkosi will be at my rescue . May God bless you tata . We really appreciate you .❤❤
Thank you Mr Nkosi. I currently don't have a physics teacher and your videos are helping me a lot. I really didn't understand anything when i was studying on my own but now i am a pro at naming compounds and i hope my marks will improve drastically.
Thank you so much for everything Sir ! You explain everything with so much care and understanding. I used to hate studying for science but you have made it so enjoyable for me !
Hi Sir. Thank you so much. I literally only found your videos last week before my P1 and it helped a lot. So now I'm watching for P2. Without you Sir I probably would have failed my prelims. I'm not confident that I passed with good grades for prelims but I'm hopeful that your videos will definitely help me for finals. Most of the Chemistry work I did not even know. So I appreciate you and may God bless you. I've even plugged some of my friends and I'm gonna definitely plug my whole Physics class cos heii we need it❤
You explained everything very well! I like how you don't rush through the work, you make things easier for us to understand... and Thank you for that sir!
Sir thank you so much , you have no idea how much you've helped me🥺 I really wish all physics teachers would teach like you... And I really wish I would have known about your channel earlier ❤️
There is an easy way to balance an equation. Eg) C3H8 + O2 ~> CO2+H2O so you first take the 8 from Hydrogen and place it next the other H like that (8H2O)and then you take the 3 from C3 and x it by 2 and you will place that answer next to CO like that (6CO2) and then from (6CO2) you multiply that 6 by 2 which is next (CO(2) you will get 12…. And then (8H2O) you multiply 8 by the 1 next to Oxygen which is 8(0(1) like that and then you take 12 + 8 =20 and you divide that answer by 2 you get 10 that 10 you got you place it 10O2 from the equation and you 2C3H8+ 10O2~>6CO2+8H20 you then divide all of those number by 2 (C3H3+5O2~>3CO2+4H2O) as you r answer l don’t know if it makes sense
Just Wanna add Sir😍I was 26%on my Chemistry on Feb. But after watching your videos now Im 64% I still can't believe 😍😍God may continue bless you Ngamandla * Thank you so much😭❤❤
mr mlungisi sir for products of elimination how do we know how many carborn atoms an alkene(s) have cause i saw you didnt quite explain well why some alkene(s) in your products had all carbon atoms and some didnt? also how do we know wich one to apply at 33:30 ?
Does the Markovnikov rule (the hydrogen attaches itself to the most substituated carbon) only apply to addition reactions, namely hydration, and hydrohalogenation?
@@MlungisiNkosi Thanks so much Mr Nkosi! Do you perhaps also have a video on naming cyclic aliphatic compounds and aromatic compounds? I'm uncertain of the extent to which they will test us in organic chemistry with regards to these.
Hi Mr Nkosi. For the substation reaction at time 13:46, why was only one chlorine substituted ? Could you substitute both chlorine’s and the left over would be 2 hydrogens ? Or will it be wrong ?
Sir for 10:00 I got 2C8H18+25O2 -> 16CO2+18H2O The only reason I questioned if my answer is right is because I was doubtful due to my oxygens not being balanced my question is Is it okay if the simplified answer doesn’t have balanced oxygen or any other molecules for that matter
Mr Nkosi im kinda struggling with the equation that you gave to us C8H18+O2=CO2+H2O I repeated this several times but still i get an incorrect answer 2C8H18+17O2=8CO2+18H20 😔🥺
Thank you so much Mr Nkosi. My physical science marks have improved so much. From 37% to 76%.
Wow!!! This is phenomenal to hear... We're creating a community of Physicists... Let's get you comfortably into that distinction by end of the year 😉

And then (8H2O) you multiply 8 by the 1 next to Oxygen which is 8(0(1) like that and then you take 12 + 8 =20 and you divide that answer by 2 you get 10 that 10 you got you place it 10O2 from the equation and you 2C3H8+ 10O2~>6CO2+8H20 you then divide all of those number by 2 (C3H3+5O2~>3CO2+4H2O) as you r answer l don’t know if it makes sense
On the markovnikov's rule you can easily say the richer gets richer and the poor gets poorer. You will know how to form the major products
Thanks!

It’s impossible to know the products… As a result, the examiner has the obligation to give you pointers.
Amazing teaching.. please how will you know it's an exothermic or endothermic reaction
Delta H greater than zero (positive) is an endothermic reaction and less than zero is for exothermic reactions
Thank you so much for your videos they are so helpful!!
You are so welcome!

Hi is it possible to shed a little light on boiling points. Thank you

Sir is Esterification out of the syllabus?
Not at all... It is still part of the syllabus.

Hi sir how do you an elimination reaction (cracking) if it's thermal cracking or cratic reaction
thank you sir 🙏🏼
You are welcome
So it implies unsaturated carbons always undergoes an addition reaction
Not always though
Thank you so much sir.👏

And sir, how do we know the condition (NaOH) is concentrated or dilute😶. Or...
You will be told or the results will tell you… If you get an Alkene as a product, then you know it’s concentrated NaOH
