How was Chemistry Paper 61 May June 2015

[Kiara P.]

I wrote flask and I labelled water in and out !

Cold water is the one that goes into the condenser and hot water is the one that goes out , nah ?

Amy other friends also wrote the same in book it's also written!

[Kiara P.]

What about that in which they asked why there is difference in temprature though both acids have same concentration?

I said it was because the ACID used in experiment 2 was stronger than the ACID used in experiment 1 although they both have the same concentration they are of different PH's
Thus the stronger acid in Exp 2 had the greatest temperature difference in comparison to the one used in Exp 1.

U indian ??

 

[FAHAD imtiaz]

I wrote acid B is better than A ! I was going to write that b is more stronger but then I wrote this! Is it acceptable?

Omg are you serious ?
Yayy !! *HIGH FIVE*

Yes I am.
How about you ?

Well , I think you should've specified it more saying it was stronger.

But hopefully they would accept your answer!
Although it sometimes depends on how good or bad your examiner is. lol.

Paki LOL

 

[Kiara P.]

Paki LOL

That's awesome!!
Such a beautiful country Paki is , HONESTLY. :')
I love it there !

I love it there !

Wow thanks for praising ma homeland !!

 

[Kiara P.]

Wow thanks for praising ma homeland !!

It was a fact yo. No need to thank me

Anyway you're welcome!
lol

 

[FAHAD imtiaz]

I don't remember my exact answer but I guess I wrote it heat ups more quickly then Bunsen burner what u wrote?

Why do we use an electric heater instead of a bunsen burner

 

[NOneed2speedd]

Why do we use an electric heater instead of a bunsen burner

I wrote as ethanol is flammable. .. it catches fire

 

[Kiara P.]

I wrote as ethanol is flammable. .. it catches fire

Me too!
I also wrote that Ethanol has a high flammability when exposed to flames, thus when using an electric heater it's safer as no flame in this case is exposed to ethanol.

 

[FAHAD imtiaz]

I also wrote that it is safer than the Bunsen burner
