how was chemistry paper 22

[sandrawrr]

i wrote C. And i guess it's right.

Do you think S is right? since it forms SO2 which is toxic?

i wrote Al

it had to be a covalent chloride

Do you think S is right? since it forms SO2 which is toxic?

yup, S is right as well.

 

[shah zaib]

it had to be a covalent chloride

and Al does form a covalent chloride.

 

[A star]

Do you think S is right? since it forms SO2 which is toxic?

yup S is right

i doubt Al. H is, though, the right one as well.

Al is doubtfull it is wrong half my friends got it wrong

 

[A star]

and Al does form a covalent chloride.

doubtfull my sir said Al is wrong idk y

 

[shah zaib]

yup S is right


Al is doubtfull it is wrong half my friends got it wrong

but the point is, Al forms a covalent chloride and forms ions when in solution. so see, it should also be correct

Al is also correct its just that it conducts electricity poorly

well i wrote phosphorus didnt go to any risky element what made u guys choose a risky one:/

 

[4hsan786]

NO2 is also toxic, right?

 

[shah zaib]

well i wrote phosphorus didnt go to any risky element what made u guys choose a risky one:/

lol...i wrote H and, too, didnt go for any risky one

 

[shah zaib]

NO2 is also toxic, right?

yes.

 

[sandrawrr]

NO2 is also toxic, right?

yep!

 

[daredevil]

no K doesnt sink it floats ans is Mg

no beeloooo u r right only possible answers are
O and N

yaar they said an element that react READILY with cold water.. Mg does not react with cold water... it needs steam to react so it sure as hell can't be MG :/

i hope the threshold for a is 45 , i have many silly mistakes , i hope ill do well in p 34 and 12.

yar it was a typo :O i said it in a comment if u deemed to read it

 

[Ahmed Khalel]

but i think physics exam made my day.

sorry i meant calcium typo

[Ahmed Khalel]

it was bretty easy exam

 

[A star]

a

but i think physics exam made my day.

ctually was opposite for me i hope phy threshold is low
