Chemistry P1 and P2 today

[Saad Mughal]

I have doubt in only two questions. MCQ 4 (the kettle one) and MCQ 33 (the one in which u had to compare in 2 fertilizers the amount of nitrogen by moles and mass)

Same here. How many have you got wrong?

Same here. How many have you got wrong?

So far none. What were ur answers to these mcqs?

what were the two ions formed in H4NO3V question? i wrote ammonium and VO3-... and i wrote ammonia for the gas produced??? can anyone confirm me this??

 

[Saad Mughal]

So far none. What were ur answers to these mcqs?

One direction and Higher and Higher. Wow. I've got 5 wrong, hoping for no more.

Bus Allah ka shukr hai. I think I got that nitrogen one wrong bcz i ticked higher and equal!!!!!!!!!

 

[mohdumar]

But some of my friends saying H2S is ionic and conduct in aqueous state because of free ions of H+ and S2- plus Mg is not extracted by coke?

Covalent + non conductor. And Mg extracted by electrolysis as above zinc in reactiviry series.

Hell no.

Oh ok...I must have remembered wrong then...I marked the slag one but while rechecking my mind started sprouting random doubts so I changed it to iron...

Iron was solid in the option whereas it is molten in reality.

Right on.

Alhamdulillah, thanks

what affect does catalyst have on dynamic equilibrium???

no effect

ppl here in my center there was so much cheating. Literally the invigilator wud come n tell u that the answer is C . The lady was young n she was trying to be so nice to all boys and the guy was being generous to girls. They were trying to be so nice so at least someone wud become their friend.
The lady was successful !!!!!!!!!!!!!!!!!!!!!!!!
i heard cie ppl r like that like that but what i saw corrupted ppl.

ye konsa centre tha bhai??

 

[Mustafa Malik]

ye konsa centre tha bhai??

naam bataya to kai masla hi na ho jaye meray liye!
i can tell British council islamabad controls it.

MCq of kettle .... I think electrons move in both directions
nd moles of Nitrogen in MCQ 33 was same bt mass of 1 was higher than the other one!

 

[passion hunter]

Favors the reactant side.

catalyst has no effect on equilibrium dude

 

[farzan]

no catalyst certainly has effect.....but if u r saying about the amount of products formation den it has not any...

Covalent + non conductor. And Mg extracted by electrolysis as above zinc in reactiviry series.

HS conducts in liquid form.

 

[passion hunter]

C3H7COOH

carboxylic acids donot combust

 

[farzan]

HS conducts in liquid form.

H2S does nt conduct electricity.......it has covalent bonds
at rtp it is a foul smellin gas!
