Last year I got level 1 both maths and physics, and I upgraded my matric I wrote in may/June while watching your videos n my marks really improved from level 1 to level 5 I'm still upgrading I need level 6, thank you so much Mr Nkosi may the good Lord bless your work... Let the cup be filled and overflow 🕯️🕯️🙏
That is fantastic... It can only mean one thing: a genius has been unleashed. There's no telling what can be achieved from now on. A distinction is on the cards
@@MlungisiNkosi Sir! Sir! Sir!!!!!🎉 I got 85% on my paper and got all the Reaction Rate Questions correct! 😊 I am so grateful, I don’t even know how to say thank you. You literally saved me! God bless you. 🙏🏾
All the best for your exam.... And please show appreciation to your teacher. First of all, they work under extreme pressure and unfortunately you are not the only one in class. Believe me when I say s/he wants you to do well as much as I do. Please buy her flowers or chocolate just to say thank you... Will you?
@@MlungisiNkosi ya. You're definitely right. Sometimes it's really easy to forget that teachers are under pressure as much as us students. Thank you for reminding, I'll definitely do that👌👌
Honestly I don't know what I'd do without you, I believe God just sent you to lessen the hardship of this matric journey, may he bless you for your hard work, for every video I watch, I shall leave a heart ❤️
Sir you are a great teacher,I wish I came across your channel much earlier👑❤️ you've taught me more than I've actually learnt and I can actually attempt past papers and actually get it right by just watching your videos in one day...I'm so greatful for u. Where are you from ?
@@MlungisiNkosi I've always been stuck at B's for physics becoz we don't have a good teacher but now since I listened to ur videos, everything is easy,this is just the extra help I needed to finally get an A for physics 🤗
Sir, i watch your videos all the time. I saw that my teacher sets up papers from the ones you use so I always enter the exam knowing how to do the question 😂
Sorry sir i want to ask about the part of zinc ,am i wrong when icheck the molar mass of the two elements b4 i answer the last question because Zn has a greater molar mass than magnesium hence it will time to reach completion
Sir when calculating percentage purity should we round of our answers during the calculations or afterwards... I rounded off afterwards and my answer was out of range
Malume,when calculating the limiting reagent neh.Don't you divide the number of mol with the coefficient of the product/substance? For e.g 2HCl number of moles = 4 There for it will be 4 ÷ 2(coefficient of HCl) Resulting in the number of moles for HCl to be 2?
Well, we know that if we use two different reactants, the reaction will not be the same even if you kept everything else the same... Therefore reaction rate does get affected by the type of reactants used
@@MlungisiNkosi I understand why the rate would've changed but how do you know that zinc specifically would've reacted slower than magnesium as opposed to it being faster than magnesium ?
@@chloecherchetty837I think it has to do with the fact that Zn has a higher molecular mass, if we remember from grade 11 IMF, more energy js needed to break the bonds
sir good day...I don't think i M a 100% solid with volume vs time garph... does sir mean that a substance tht is solid will have a less gentle curve thn one tht is powered??
@@happytagged7724 the only factor that affects the shape is temperature. The higher the temperature, the lower the peak of the curve and the wider the distribution becomes.

Congratulations on such a remarkable achievement. Thank you so much ♥️
Congratulationssss this is big!! now i have hope bc i’m also upgrading this year and people have been saying rewrites are useless
Congratulation. I'm also upgrading this year, this is giving me so much hope.

Me too hun❤️
Thanks to this channel from 63% to 90%❤

I have an exam in a few hours, you've taught me in 2 hours more than my teacher did in 2 months. Thank you so much.

@@sarahm.a4782 this is the best comment by far ❤️❤️❤️❤️❤️
How was your exam?
@@MlungisiNkosi Really good thanks to you!! A question came out that was really similar to the one you did in this video😁
Honestly I don't know what I'd do without you, I believe God just sent you to lessen the hardship of this matric journey, may he bless you for your hard work, for every video I watch, I shall leave a heart ❤️
Thank you so much. ❤️
You are such a great teacher keep it's up....I even got excellent Mark's on both of my papers
That's great! Keep up the good work... What do you want to study when you finish school?
You are a life saver God bless you for this
I'm starting to get good marks
It is my pleasure ❤️
Sirrrrrr I got the last question all by myself!!!! 🎉
Yippiiieeeee!!! 😊
You are a great Teacher. Thank you so much 🙏🏽🙏🏽
You're welcome. And thank you
This has been really helpful... You are amazing... Thank you 💃💃😘😭
Thank you... I'm glad you found it helpful. Good luck as you prepare

Loving the content!
Thank you so much
Sir, i watch your videos all the time. I saw that my teacher sets up papers from the ones you use so I always enter the exam knowing how to do the question 😂
Well well well.. Uncle is literally handing you the exam on a platter 🤣.
Sir how did you know that HCl is 2HCl on the equation
From 60 to 99😊
Sorry sir i want to ask about the part of zinc ,am i wrong when icheck the molar mass of the two elements b4 i answer the last question because Zn has a greater molar mass than magnesium hence it will time to reach completion
Sir when calculating percentage purity should we round of our answers during the calculations or afterwards... I rounded off afterwards and my answer was out of range
I think you’ve answered yourself… You round off at the end
My question to those who downloaded the senior certificate paper. When was it written?
Thank you very much for the informative video!!!!😄
My pleasure!
Malume,when calculating the limiting reagent neh.Don't you divide the number of mol with the coefficient of the product/substance?
For e.g 2HCl number of moles = 4
There for it will be 4 ÷ 2(coefficient of HCl)
Resulting in the number of moles for HCl to be 2?

Keep up the good work 🤗❤️
Thank you bhut' Mlu🙏🙏
You're welcome Mandisa
thank u very very much sir... 😀
You are most welcome 😊
Appreciation from Frankfort Free State 🙏
Wow!!! Thank you so much
Thank you sir 🙏
You're most welcome
How would I know if zinc will react slower???
You can't unless you've done the experiment before. The examinor should find a way to hint it.
@@MlungisiNkosi we whew 😅 thank goodness I thought it was like something I should now
Thank you so much✨✨
So if they ask to calculate the mass of the impurities present.Is it the same has as percentage yield.
Hi Precious, just watch the next video on Stoichiometry on percentage purity. You will be sorted 😊
@@MlungisiNkosi is it already out
Oh thanks I just watched .you are the best,you make it seem easy and regain my confidence for 100% Wish you did maths too 😁
@@preciousphoku5654 I'm glad I can be of help and to have restored confidence. An A-student has been awakened
@@preciousphoku5654 I'm glad you found it
Hi sir, how do we know that Zinc reacts slower than Magnesium? (This is referring to thr very last question)
Well, we know that if we use two different reactants, the reaction will not be the same even if you kept everything else the same... Therefore reaction rate does get affected by the type of reactants used
@@MlungisiNkosi I understand why the rate would've changed but how do you know that zinc specifically would've reacted slower than magnesium as opposed to it being faster than magnesium ?
@@chloecherchetty837I think it has to do with the fact that Zn has a higher molecular mass, if we remember from grade 11 IMF, more energy js needed to break the bonds
I thought temperature increases the peak of the graph and shifts it to left
Lower temperature does that
Sir, does that mean that the smallest number of moles are the limiting reactant always?
Not really…
🏋️👏👏👏👏
You're most welcome
sir good day...I don't think i M a 100% solid with volume vs time garph... does sir mean that a substance tht is solid will have a less gentle curve thn one tht is powered??
I'm not sure I quite follow... Are you referring to the Maxwell-Boltzman distribution curve?
@@MlungisiNkosi yes sir
@@happytagged7724 the only factor that affects the shape is temperature. The higher the temperature, the lower the peak of the curve and the wider the distribution becomes.
@@MlungisiNkosi understood!👌thank u sir
@@MlungisiNkosi maybe he means the rates graph .the one where the gradient is the rate .
Sir how did u know that zn reacts slower than Mg
Well, it’s somewhat insinuated in the statement when they add a catalyst
Why is the expiremnt of zinc differ 🤔
How do you mean?
🙆🏽♂️🇿🇦😋
Tomorrow 😊
Thank you sir ,l do also wish to have an Electrolysis video from you
Rate of reaction
And reaction rate is it the same thing?
Yes
Sir wouldn't the excess mass be 0.005 instead of 0.006
Moles*
Is that what you got?
Sir I think you made a mistake ko mass ya excess HCL
How so?
Are you grade 12?
Bc i’am grade 2
I’m not sure I follow
U Made a mistake by the mass it is 0.32
Ok thank you
Can we please have an update of this topic please🤧😭
I will provide one
but everything else is 👌
Awesome!!!
So when you were looking for the yield you did a mistake because 32 multiply by 0.01 it's 0.32grams not 3.2grams
