Chemistry P1 and P2 today

Yeah that's correct. I misread the question.

wrote only reacting with potassium maganate no color change mentioned

 

[Aly Emran]

I dont know if this was answered before i missed about 35 pages of the thread but what was the answer to the mcq in which a mixture of copper and zinc were added to the iron compound I chose the option which said solution got colourless and red-brown ppt. formed is it correct?

ur rite

 

[Fraze]

ur rite

Sowwweeeeeeeeeeeeeet thanks a lot

correct!

 

[Fraze]

i guess i lost and A* cox i think i might get 155 or 156/175

For what its worth, if the threshholds drop by even 1 percent, you get an A star as they round off any decimals to the nearest whole number

wh
aat did u wrote in electrons qstn?

I wrote that the electrons travel in one direction im not sure if im correct but my opinion is that the question had nothing to do with heat conductivity at all because although it was an electric kettle, i felt that they were talking about the conduction of electricity to the heating element rather than the conduction of heat from the heating element. Then again i may be wrong

ahan i have a question related to chem ATP what was the temperature after graph question was it 4.2 or 29.2?

i seriously dont remember sorry

 

[Fraze]

pprs were easy why would they even drop threshold

good students like you ( you sure sound like one ) think that it was easy but what about the other half of the picture? maybe theyll drop it to 89 88 bcoz there are still people out there who screwed up enough to fall below C

 

[Shadow]

this question can save my grade

i get a feeling it was 4.2, but i dun even remember the wordings still 4.2 luks more familiar

It was of 2 marks, you had to mention at least 2 of these:
- oxidizing with an oxidizing agent.
- colour change.
- no bunsen burner used since ethanol is flammable.
- apparatus description.

Bhai saad mughal what about the mark for reactants and products of the process

what about the mark for products and reactants sir?

ahan i have a question related to chem ATP what was the temperature after graph question was it 4.2 or 29.2?

In that question, maximum temperature was asked so it was 29.2. We had to read temperature rise from the graph and add 25 to it

I wrote colored compound. It's a life saving property!
Don't worry, you might still get the mark.

It said, "What property does V add to this compound?" I wrote high melting point there was no other metal in it. A metal in it would make the compound ionic, and hence, raise it's melting point.

 

[Taha Haqqani]

Lol, Taha!
BTW, how was P2? Couldn't talk with you after it.

it was great!...i expect good..lets see..

 

[Saad Mughal]

I'm talking about another method for preparing Ethanol.

Yeah, that's what I'm saying. Your answer is correct.

Yeah coloured compound was so obvious. And this answer is confirm as ammonium metavanadate is yellow.

Btw Honestly i think everyone should forget chemistry and focus on the next papers. Its too late now.

it was 29.2 as u had to tell final temperature NOT the temp change. Many ppl fell for this.

Well, I probably should, I'm getting depressed now, doubting my ability to even get an A*.
But Physics and Maths are easier for me so I'll just practice past papers now.
