Thank but we need physics tooo
Nice video sir what of qualitative analysis just like did for WAEC
Hats off to you sir❤
@@BlossomOladapo-yc7sx Thanks for your kind words 🙏 We are working on the qualitative analysis and when we are done it will be posted soon ✅
Best teacher of all time
He helped me through my Waec, jamb .
Now I'm already watching neco own too❤
Thanks
Thanks sir
God bless you sir
God bless sir this was really good explainations....likewise ur results and methods r exceptional hats off to ya..and i got 0.0315dm^3
thank you so much, you are doing well... May GOD continue to bless you.
Amen 🙏 Thanks for the prayers
Good job sir, You have helped alot this year , thanks 👌
Thanks for your kind words 🙏 I sincerely appreciate
I got 31.58cm3 or 0.0316 dm3
Please, what is the volume of CO² released in 1 dm3 of b
Thank you so much sir😍
You are welcome 🙏
Thank you sir
I have been waiting for this video since.
Now it's here ✅
God bless sir
Amen 🙏
Volume of Co2 gas evolved is 1.264 dm³ or 0.031dm³ if the amount in 25cm³ is used.
Correct ✅
@@askchemistryhangout the former or the latter.
0.031dm3✅
I got 0.03158 dm³ of co2 at stp
Pls explain sir@@askchemistryhangout
Welcome sir
Thanks 🙏
Well done sir, I sincerely appreciate your effort. I want you to assist me on how to calculate theoretical or assumed titre value
Please chat me up on 08100059151
I mole--------22.4 dm³
From the equation reaction, there is one mole of sodiumtrioxocarbonate( iv) also one mole of CO2. If am not wrong, volume of CO2 produced at STP is 22.4 dm³
You got the starting but didn't finish up well.. So your final answer is wrong ❌
Sir please explain @@askchemistryhangout
More grace 🔥
Thanks 🙏
OK sir
We used 3 decimal places in WAEC Sir and not significant figures. Were we wrong Sir??
For instance for the concentration of A in Mol/dm3, we wrote 0.068 instead of 0.0684. I will correct that this time around in NECO but I just want to know if the way we answered in WAEC is wrong.
It's to three significant figures ✅ 0.0684 is much more better ✔️
It's 3 s.f
I have been waiting for your video.... Thank you sir
You are welcome 🙏
@@askchemistryhangout Sir Can you kindly also do for salt analysis
@@blessingokoro6616 I am on it and will be posted soonest ✅
@@askchemistryhangout Good morning sir, trust your day is going well
Please I am a new chemistry teacher and I not too familiar with external exams
Please the teacher report sheet that will be given to us during chemistry practical exams in NECO exam is it same one that was given to us during WAEC
Just to fill in our titre value
Please Sir I will appreciate a reply 🙏
Thank you
@@blessingokoro6616 yes the report form is the same with that of NECO
Weldone sir
Please sir explain more on this titre value because what you said during waec exam is that if the titre value of a school is 20.20 the students can form there own to be 20.23 or 20.27 but it must not exceed the range of 20.2 something pls explain more better sir .
The lord will continue to help you.
No, the range is + or - 0.1 - 0.2
Good one sir would this literally come out
This is just a prediction.... But we believe anyone that thoroughly and carefully watch and understand this video should not find the exam extremely difficult ✅
The volume of CO2 is 0.0137dm³
Correct ✅
For volume of co2 gas evolved 1 got 0.316dm3
Check well there is a slight omission in your value
0.0316dm^3
@@mistaforworks correct ✅
Where are you people seeing vol of co2 at stp? It's not in this question
I mentioned it that anyone that watched the video should calculate Vol of CO2
@@askchemistryhangout okay sir. Thank you so much!
Pls which year is this question
It's just a question predicted by me for the 2024 neco practical Titration✅ it's not from any year
Volume of gas at s.t.p is 0.0315 dm³ please check Sir
Correct ✅
How please 🥺
Watch the video again carefully
Kk
Please where are you teaching from
@@user-yf9tf6bv1c Lagos, Nigeria ✅
I think while calculating the mass of Na formed and the number of H ions from H2SO4,
Both the value suppose to be = 2X and the moles will be divided by 2 rather of multiplying as you did it.(my thoughts)
Please, I'm not clear about it, can you elaborate more on them.
1.52dm3 of CO2 is liberated at STP
That's wrong ❌
@@askchemistryhangout How is it wrong
The volume is in 1dm3
@@WilliamsAnaiho The volume of the base prepared is in 1dm3 but the volume used for Titration out of the 1dm3 is 25cm3✅
@@askchemistryhangout if that is the case 0.0313dm3 of CO2 will be liberated at STP
My X was 1😥😥
It's not wrong... If your titre value has same range with the one your teacher filled in the report then you are correct ✅
Sir I have 0.03525
Is it correct
It's close to the correct answer... The correct answer is 0.0316dm3✅
@@askchemistryhangout I will try again and what should I do to get the correct answer
Isnt 20.60 too high sir 😮
Hmm my teachers end point is 22.50
@@BlossomOladapo-yc7sxI am a student sir 😅😅
So that means the acid is weak
I disagree on your calculations on mole
Mole is given as mass in grams over molar mass and not mass concentration over molar mass
God bless you sir
Amen 🙏
