Yeah same, calculations did take some of my time!
And I got the mass as 12.67g wbu?
Good luck for tom's bio p4!!!!

 

[AvgStudent]

i got the same as well its right im sure

did you have to give the mass to 2 d.p? i gave it to 1

 

[HELLNO]

i gave it to one as well

I gave it to 2 dp since the balance measures up to 2 decimal places... Idk, I think either ways are correct

I wrote that the reaction has just started, and the increase in temperature was rapid, so it was hard to determine one certain value at 3 min.
And to why he took from 0-2 min, to measure the initial temperature and ensure a constant temperature.
Wbu?

i wrote, the CaCl2 was added at tht tym
n yh 2 make sure temp was constant. i missed the point of initial temp :/

Its okay, it was just for one mark, so one point is more than enough

I doubled it, it was 5.05... I made it as 10.1
Thats because the depth decreases, and the saturation of particles increases therefore it doubles

 

[HELLNO]

This part was messed up, some made it constant, others doubled it!
But my teacher says it should have been doubled... so idk whats right!
