Nah Burette isn't correct.... Using a burette is a slow process whereby a tap is used to slowly drip one liquid into another. I'm pretty sure it's meant to be measuring cylinder as it said 50cm3 not 50.0cm3 also it said quickly not drop by drop

Purple@white do yuh rememba some other question??

dnt think so.......

 

[Purple@white]

and the question about the iron and painted iron in the inverted test tubes? like does it fall or rise or no change?

rise & no change........

yea u r right...

 

[Purple@white]

the first question about which instrument u need to use was it a burrete?

measuring cylinder........

 

[Purple@white]

I was confused about that question of petroleum..I wrote boiling point for number one of them, was the other one supposed to be chemical reactivity or long chain sumthing?

long chain & boiling point

 

[Fatima18]

long chain & boiling point

I wrote boiling point and chemical reactivity. :S

and the question about the iron and painted iron in the inverted test tubes? like does it fall or rise or no change?

First was rise and then no change.

measuring cylinder.

measuring cylinder.

oh really well i thought it was burette cause measuring cylinder is usually when they tell u to measure it but idk maybe its wrong

 

[nigga7]

First was rise and then no change.

exactly!

sadly , its right....

 

[K1D]

exactly!

My friend told me that the answer is one rise and one fall ,cause experiment was done in the same container, same volume of water, one rise one must fall

 

[D4nyzz]

burette!!

The answer should be measuring cylinder as the question ask for quick transfer of liquid. But if they ask u for accuracy then the answer should be burette.
