In the third column, it says to submit the Astral answer to the Two-to-Two-Meal question.
It should have come sooner; Filal, it has already started.
For this, we need chemical kinetics for the best experiment in chemical kinetics.
Chemical kinetics requires chemical kinetics for the best experiment.
We will have to perform parameters and per experiment for the chemical kinetics best experiment.
It's time to look at us now. Let's move on to the reaction part. How does the reaction go? So, please watch carefully in the theory.
The formula for the reaction of Thioacetic acid with sodium hydroxide is CH₃COSH + NaOH → CH₃COONa + H₂S.
When mixed with Syl, precipitation occurs there, forming Salpet, which will be white in color.
The solution will be milky white, that's correct. You'll know when it starts forming.
It will proceed toward reaction completion, increasing thereafter, followed by the formation of other substances such as sulfur dioxide gas and SO₂. Continuing to rise, these are the aspects relevant to our operations, specifically within the chemical kinetics section of the operations.
What all things need to be measured? We'll need a measuring cylinder, right? Four conical flasks, okay. And these tiles—just that much is enough. If you've done even this much, that's already sufficient. Right? For proper cross-marking, I've already marked it here.
Need to see the proper cross mark, Fern.
Now I start filling in the solution here.
Alright
First, in the conical flask
I will need 20 ml of 0.1 molar thiosulfate.
How much will it cost?
20 ml
What are you writing, everyone?
Table number 1
Come on
So, what should I do with 20 ml of sodium thiosulphate?
I will take cover.
40 ml
How much should I cut in the next one?
50 ml
50 ml has been reached and remains
You all are talking
You show 40 ml as well
50 ml of mustard oil applied
Okay
Come on
Now look at everything
To dilute with water
Add water
How much was it before?
28
Then
18
Then 8
Then first, I'll take cover.
28
water
Alright, fine, you guys make your own then.
Then in the second one
Will go
Chan Taro, not yet
So first I'm 28
Alright, tell me how much to bet in the next one.
18
Look, the dilution is decreasing.
Writes in the second one how much is 18
What is 8 in the third?
And in the fourth one
Nothing at all
I mean the fourth one belonging to you
You will administer 2 ml of saline in the first one, right?
What will you do with the turbo stop watch? Will you turn it on?
You'll do the second one, then the third one
Don't continue; do as I tell you, just like Bilbul does.
But the second thing after Milkie White's conversion
You don't have to look at it with your naked eye
And its cross which is
What I did to Mark is to make him lose hope.
It shouldn't be visible from inside these liquids.
We pay VAT until the cross-cross mark becomes our dissipation.
This is the flaw, look here, the milky white thona has already started
He performs the ritual.
29 seconds
Alright, let's go.
The first one is complete with my reaction.
Write something down, any
1 minute 59 seconds
Sorry, 59
It's from before 159, okay
Alright, I'm restarting this.
What should I bring back the second time?
They said this about me
I'll take back 2 ml.
2 ml of this
I'll dodge and from behind I'll stop watch
What should I do? I'll do it, that's fine.
Okay, let's see it.
When does it start to disappear?
Broke concentration
much more than
More of this and this and even more
And more and more and even more
Alright
Any one student
I will create a graph based on this reading.
He's fine, I'll talk to him.
You go first
The class is still ongoing, as far as I can tell.
Actually, Naz
The reading you are receiving right now
He got 1 minute 59 seconds.
You are there column
You will see it there in the column.
You need to write it in seconds.
So how in seconds?
You wrote it, it has come in a minute.
So 1 minute equals 60 seconds.
It is 60 plus 59
How much is the total then?
Will you fill it up there in the second?
Alright, don't write it down in a minute
Now this should also be the same
It has started.
Oke and
Khatam
One minute
Twelve seconds
Alright, now we'll move on.
The third one
The third one is more focused on us.
So this
He will come soon.
One minute twenty seconds
For your declaration
Dhikshit, hurry up
This is a highly concentrated solution.
Alright
I didn't even add water to it.
Clear, this one atual
Here it comes
Daim will come in the forked path.
It should come very rarely, that's correct.
So you've figured out one thing: which of us is reacting quickly and which is reacting slowly here.
Writing? Even the milk with water will become harder at that time too.
Are you writing? But can we drink this milk?
