why are you still hooked up in this question? LOL Definitely one wrong, the unshared electrons one. Maybe two OR THREE MORE. What about u??

That Ca(OH)2 one, you are right. But i checked a previous marking scheme, the normal neutralization equation would be acceptable too.

Well, i got one wrong in atp (Because i hadn't done Oct-Nov 2007 paper, the question repeated).
And that Polyunsaturated one, didn't write ''Carbon''.. because hadn't read that chapter. 1 mark there.
And wrote ''Sugar''.. in that hydrolysis question, hadn't read the last line of the syllabus. Maybe ''Sugar'' will be accepted, but idk. .-.

And probably many more.

So you're sure about losing one mark, but not others.

What was the answer to that loss of nitrogen content? :/

What 2 points were required to get 2/2?

You checked it?Stealing credit hmmm?naughty naughty

Reacts with that alkali...forms nh3 gas which escapes carrying wit it nitrogen thus content is lowered.

Lol, okay.. Faizan Muhammad checked it. But i instigated the thought in his mind.. that led him to go and check.

 

[PerseusTributePotter]

and what was the answer to that mcq that asked---which one will not react. with options zinc hydroxide,zinc carbonate and other.i dont exactly remember the question.

(D) Zinc Nitrate.

To how many significant figures do we have to give our answers in physics and chem?

 

[asadalam]

3 S.f

3 S.f

And if i don't do that? Then i'll lose marks?

Depends...how many did you quote...3-4 are acceptable.

 

[sid2333]

Possibly. But it can be okay sometimes to quote answer in 2 s.f rather than 3 s.f. For e.g, take chem's paper. Most of us wrote 62.9% right?? But it can be okay if you had written 63%

But the moles questions in atp. I didn't round them to 3 s.f They were all full answers, as on calculator.

That doesnt matter.Many MS have long answers for those moles Qs so dont worry

ahem ahem?
instigated ?

Lol, i told you about that question, and that caused you to search the marking schemes.
Had i not brought that question up, would you have even picked up the chemistry marking schemes to look for that question?

Had you not brought up the question I would have kept thinking I was right
