Chem p51 discussion, it's been 24 hrs

[Thampi4]

I think 24 hours is up now so we can discuss the answers now

 

[soccerprinc3]

x was 7 right?

 

[Thampi4]

That's what I got as well

For q1 what hazard did put

x was 7 right?

my hazard was that iodine is irritant so use goggles and wear chemical resistant gloves

 

[Starry_night]

I got gradient 7 too! the first part was that solubility decreases when temperature increases because equilibrium shifts to the left (Le Chatelier) right?
Also what anomalous points did you get?

 

[Thampi4]

Yea

I got 2 anomalies
One above the line and one below

For the one below the line I talked about incomplete heating cuz it lost too little mass
And the one above I talked about some of the sulfate being decomposed cuz it lost too much mass

What were ur hazards for q1

 

[Starry_night]

What were ur hazards for q1

Yeah same. I put that iodine was irritant and to wear goggles and resistant gloves.

 

[Thampi4]

Yeah same. I put that iodine was irritant and to wear goggles and resistant gloves.

Nice

What points did u put for the 8 mark question in q1

 

[Starry_night]

Nice

What points did u put for the 8 mark question in q1

that wasn't easy, mentioned apparatus with capacity, some calculations and conclusion on how the titres could have been accurate and so on. I think i messed that up a little... what was the indicator? also the very last question of the paper was the one where we had to state the value of x and explain right?

I didn't use an indicator, I used the colour of the iodine solution as the indicator
X was the same as the gradient 7 so the formula was FeSO4.7H2O

Explanation was that gradient is same a mole ratio between water and FeSO4

 

[Thampi4]

I think I'll get 3 out of 8 for q1c

 

[Thampi4]

What's ur next exam
My next exam is mechanics 1

Yeah! But there weren't any more part questions after that were there?

 

[Thampi4]

I don't think so

 

[Starry_night]

What's ur next exam
My next exam is mechanics 1

same, I have mechanics 1 on monday

 

[Starry_night]

I don't think so

ok, i was afraid i didn't turn the page and missed out questions...

 

[Thampi4]

Yeah! But there weren't any more part questions after that were there?

Could u check with others if there were any more questions?

 

[Thampi4]

ok, i was afraid i didn't turn the page and missed out questions...

ok, i was afraid i didn't turn the page and missed out questions...

It was a blank page
Cuz they didn't mention to turn over or that it continues until next page

Did u c anything like that

Also how many marks was it to find the dependent and independent variable

 

[Thampi4]

Could u check with others if there were any more questions?

No more questions were there
I remembered all their marks and when I added thm I got 30

 

[Starry_night]

Could u check with others if there were any more questions?

no i just thought about it a few hours ago, i'm pretty sure there wasn't any more anyway.
