How was Chemistry P1/2

[MustafaMotani]

I wrote magnesium, i think ur explanation is OK.. but still have some doubts

 

[Monojit Saha]

Hey do you know how much mark this question WAS, i completely forgotten this question even though I ATTEMPTED THAT!!

OHh,, just 1 mark for the identification.

table said so aur waisay bhi reactivity series ... its copper. how on earth is it magnesium? any proof?

yeah it's copper . i first wrote sodium , but then remembered that sodium is most reactive and it's compound will be the most stable so the answer should be the metal whose compound is least stable. so i cut it and wrote copper .

chemistry aapka sub ho ga meray se tow bilkul wo dil nahi lagata.. naa hi apnahiyat mehsoos honay deta hai dash.. apni trf se bakwas hi bakwas likhi hai..:/

then dont worry, u'll get A inshallah

 

[Scarlet Flame]

then dont worry, u'll get A inshallah

hahhaha.. wow... i dont xpct As in either chem..nor bio..nor geography..:/

 

[theViperace]

did the same..... i dnt know why people are saying that magnesium carbonate was the least stable...actually magnesium carbonate was the most stable...........

To prepare Copper Chloride , never ever we can take sulfuric acid. You have to take HCL to prepare all the chloride salts

 

[theViperace]

my all answers matches urz i hope all are correct now!

Yeah mine as well. I took the same volume i.e 30 cm3 But i thought k it was wrong.

those processes can be simply termed as oxidation of methanol I surfed the internet

Alcohols can be oxidized into Carboxylic Acids on any given day

i knw!! thats wt I was saying ...

I want to ask one thing- well in configuration question I just wrote the configuration but did not make the shell diagram
will i get marks?

i dont think so as they wrote draw a "DOT AND CROSS" diagram

nt all of the marks...there are marks for making the diagram...

Hey,, In paper 2, section A what was the least thermally stable carbonate? Copper or magnesium?

It's copper.

hahhaha.. wow... i dont xpct As in either chem..nor bio..nor geography..:/

so what? baki 5 tou hain na kya pta un me aa jae aur wese bhi agar 3 sbjects me cnfusion hai tou un me se kam az kam ek tou acha ho jae ga atleast i believe lo phr 6 As tou ho gae, thorey hain?

 

[maryam fatima]

yeah, least stable was copper, kyu k question me dia hua tha k thermal stability reactivity pe base krti hai aur jo options theen unme copper least reactive tha

hahaa.. an optimist huh?? btw aik B urdu mein aa chukka hai..

 

[silver slick]

I think there were two questions regarding configuration, the question in which it was stated draw dot and cross diagram,
well I drawn it there ,but there was another question which ask to configure, in end only 2 min were left so I configure it.
is there anyone who remember any such question, or was i really halculating in chem paper

hahahhaha every one say that i'm optimist and i'm giving u the guarantee that ur result will not be disappointing for u

no regret, I also got B in urdu..
