How was Chemistry P1/2

[Scarlet Flame]

I can . But won't .

level...

 

[multixamza01]

level...

 

[Minnie]

still confused! i did D u??

i did D too.

 

[fatikhalid]

i did D too.

y r ppl saying it was b?? o_0

 

[multixamza01]

y r ppl saying it was b?? o_0

which one?

 

[Spidey21]

SOURCE OF HYDROGEN ?????????????????????????????????????????????????????????

Cracking of Petroleum...

 

[Doosh Bag]

If the 36th MCQ is being discussed. It was D.

 

[Mayedah]

it was option C the one with silicon oxide and calcium oxide i guess !! buh whatever surely it was option C !!

Thanks i did the same !

 

[Mayedah]

Correct. But it was sulphur, not silicon.

Thre was no option of sulphur ...there is no sulphur reaction in blast furnace !

 

[Doosh Bag]

Thre was no option of sulphur ...there is no sulphur reaction in blast furnace !

Sorry. But answer was C to that. SiO2 + CO -> SiCO3

 

[Mayedah]

Sorry. But answer was C to that. SiO2 + CO -> SiCO3

Haaha thnks i got confused too

 

[Minnie]

y r ppl saying it was b?? o_0

yes thats what im asking.
whenever im like okay mine was wrong, someone posts that it was D. :S
D OR B??? :

In the last question of section B (a) part
was it that if we increase the temperature of the reacting particles the particles will absorb heat energy due to which their kinetic energy increases and the no of effective collisions increases hence rate of forward reaction increases as he was talking about (affect reacting particles not affect of aquilibrium)

 

[Matrixxx]

can we also write meat as a type of food in fats

It was exothermic reaction so it would be backward reaction !

wasn't the molecular formulae of No2= N4o8 and No2 is an empirical formulae and do we have to take the volume if concentration of KOH 50cm3 or 30cm3

yaar lekin logon k achay bhi tow hove hain papers..:/

I know. All i am saying is that its will not change answers that u wrote in paper!

 

[UziB]

Why?, i thought you did well.

Thats what I thought too, until this forum proved me wrong koi nahi, percentile down hua toh A* aa jaye ga nahi toh an A is secured for sure inshAllah wbu? Tumhara kesa hua?

 

[Doosh Bag]

yeah same ques 50 or 30
