Chemistry Paper 61

so, It's desplacment!

AND it's exothermic!

Some people on this community are just too dump. "That answer was displacement", "No it's Exo" "How did you know it's EXO " "Because all displacement are EXO" "So it's displacement? " "No it's EXO"

Exothermic - Displacement - Precipitation

Retard. Accept it. It's freaking EXOTHERMIC! . It's either Endothermic or Exothermic. *Facepalm*

Goodluck in discussing.beleive me ,
that won't change your marks peeps

Yeah, we're just discussing what were the areas we got wrong.

 

[Nawaf Dandachi]

Has anyone notices that get 7 marks out of 80. You get an F in Paper 3.
Get an 37/80 get an A? very low curve

 

[pudge919]

I see man , but chill up
tune in to ASOT 561 that wont bother you as much as the exam !

the height were all the same because 5 cm^3 used up whole of 3cm^3 of lead nitrate which gave 24cm height. therefore any amount bigger than 5 cm^3 reacts with 3cm^3 of lead nitrate you won't get anything more besides 24 cm. basically all the lead nitrate gets used up when you have the other substances which is 5cm^3 or above reacting with it. so maximum it goes is to 24 cm

Can't you just say KCl is in excess

 

[Patum]

LOL Beleshti.. What ever floats your boat mate. :L

 

[Omar Hosny]

How to speed up disolving in number 3, you don't say heat, as they told you the water is hot.

Say " Stiring with glass rod"

Basically your answers are 90% identical to mine lol

Eshta asa7by.

 

[Omar Hosny]

Did they say so?

Exothermic is correct but didn't write it cause there was no indication about temperature but i think it will be right as displacement reactions are exo

 

[Patum]

Can't you just say KCl is in excess

Yea I think I wrote that.. there was a more than enough amount of KCl to react with the lead nitrate therefore if the KCl amount increases it still wouldn't affect the height of the solid forming at the bottom because there is nothing for the KCL to react with to form the solid.

The second graph is line of best fit. 2 points may not intersect.

i had one point out

Nope, I'm Lebanese. But I got some Egyptian friends haha

 

[Nawaf Dandachi]

yeah first two points don't intersect.

 

[Naser Al-Ayyoub]

When trying do add mt marks for grades thersholds, there is always an extra 40 or 20 marks of the total marks syllabus. What is it for?

 

[aliasal]

In the qualitative analysis table. about the HCL+W , it's worth 3 marks so say

Bubles and Fix as C02 produced. C02 turn limewater milky

they clearly stated write only observations i dont think the word CO2 is an observation i said a colourless gas
