How much marks was the last part of the last question? 1 or 2?

 

[Ahsan Zafar]

9.4 and 5.64

Also did u guys extend the intersecting lines out of the grid.I did but erased most of the part so I have small but still conspicuous intersecting lines seen on the graph.Do u reckon it,s correct(I know it may seem ridiculous but just wanna know tht even if small part after intersection is presented but still they r visible(mine went till end of grid tht is 2 small blocks of intersecting lines)

You had to intersect or you wouldn't get the max temp. You intersect them and they intersected around 9.8-10.

off white?

Correct tht is another option I forgot to mention

Yup i think these were them.

I did intersect them I mean the lines after intersection if extended wud go out of graph ,only some part wud be in the graph,so I remoed the outer part and allowed the part after intersecting IN THE GRAPH to remain.So again wht do u reckon

In November 2007 it has 1 marks. And one line.
But in our paper it had two lines, one for H and for the other solution. :/ Doesn't that mean 2 marks?

MODERATOR EDIT:Such conversations would lead to immediate discontinuation of all the concerned accounts.Stop at once!
Haha ..Just joking
But really I think we r violating some known rules.

It was the same question. 1 marks

 

[Dark Destination]

It was the same question. 1 marks

But their were two lines this time, separately for both solutions. Some people are saying it was 2 marks.
Are you absolutely sure it was for ONE MARK?

one mark 100% sure

 

[Adeena Shamshir]

does anyone remember d answer of last part of last question in today's paper (chem ATP)?

 

[Dark Destination]

An electric heater or water bath in question?
I think both r correct as they serve the same purpose,gentle heating and preventing combustion

How were we supposed to draw the heater?

I wrote CREAM for Silver bromide. Is that correct?

there was an electric heater in a question diagram, but yea both are correct according to me.
