13 to be exact and you?How many pprs did u do?!

2008-june 201313 to be exact and you?
ryt!Yes, two with methanoic acid, one with ethanoic and one with propanoic. So total are 4.
Sir,I appreciate your help to all of usOk, guys. Its past midnight for me.
Time for me to log off.
If things go well, I might be back for the November batch, perhaps some of you might be kind enough to help them also since you have already ploughed through the questions in your current preparations.
All the best for your papers and your soon-to-be achieved freedom from exams.
This question please! :'(
need help in this questionIn Kc we do not take the concentration of the solid. So in this case we will not include the concentration of Ag(s)
So it will be as follows:
Kc= (0.56) / (0.44^2)
= 2.89
That's option D
according to boyle's law, p1v1 = p2v2need help in this question
Q: flask X contain 1 dm3 of helium at 2kpa pressure and flask Y contain 2 dm3 of neon at 1kpa pressure.
if the flasks are connected at constant temperature, what is the final pressure?
A: 4/3 kpa
B:3/2 kpa
C; 5/3 kpa
D:2 kpa
how do we solve it and answer is A
my last question, but will work out step by step with your input.
Can you work out,
moles of Ti+ : mole of VO3+ ?
Metanoia http://papers.xtremepapers.com/CIE/... AS Level/Chemistry (9701)/9701_s13_qp_13.pdf q8 the ans is Dyes i made a mistake. it had to be x²
That'll be 3:2
Got it! Thank you so much!From half equation,
Tl+ --> Tl3+ + 2e
So 3 moles of Ti+ loses 6 moles of electrons to 2 moles of VO3+
1 mole of VO3+ gains 3 moles of electrons (oxidation state will decrease by 3 units)
V in VO3+ has original oxidation number of +5.
New oxidation number = +5 - 3 = +2
