i dunt think dat u get a 0 cz its written in mark schemes that answer upto 3 significant figure is considered. beyond these 3 sig. fig, one mark is deducted over all

U just have to write no ppt thats all or very faint almost invisible ppt formed !
nd wat was the answer to that chromatograph apparatus..it confused me

For the last ques u had to find the mass of the solid dissolved by using the formula given and then minus the given mass in that part which would give u 68 g i think !
For the chromatography what was the question i forgot it can anyone tell me that !

but hte real answer was tht we have to add a sucking stoper in order to protect the liquid to get in to our mouth while sucking.

we dont always suck it. do we ?but hte real answer was tht we have to add a sucking stoper in order to protect the liquid to get in to our mouth while sucking.
we also use it by hand and maybe that is why we need gloves.
its just my point of view.
