Chemistry: Post your doubts here!

[Suchal Riaz]

How is it against the Term and Rules ??!.............Many people have a signature like this
Also..there is a better way to ask me to remove it

i was requesting you to remove it and also telling you about rules. i wasn't threatening you. if you won't remove it then go ahead do whatever but don't waste my time i have to solve doubts of other people.

Thank sachal for this

all C=C can show cis-trans
it's more like permutation of mathematics.
first C=C can be cis and trans, second can be either, third can be either
there are two arrangements for first, two for second and two for third: 2*2*2=8

Is this POLITE way to reply ??!
Just think and answer ur self . Dont reply here cuz this is for CHEMISTRY DOUBTS
ANYWAY, I will remove RESPECTING THE RULES

Chill out man
You do realise that the rules also state that no user can act as a moderator

You should have just requested him and not brought rules in.
Peace now!
GCE As and a level bro please remove the pic if possible or otherwise make it a bit smaller.thanks

how do you know about permutation that much you dont even take stats
but great trick there i didn't realize it myself

Q6-c ( i got D 21.6 i did the calculation twice got 0.06 mol 7dm^3 and temp 303 n calcultaed it using them )
Q20-c (plz write the calculation)
Q24-A ( octene ha c8h18 so wen it cracks the products will add up to be with in the molecular formula of octene ryt)
Thanks.

q20:

propanol and sodium ethanoate will be formed. Mr(propanol):60 Mr(CH3CO2Na)=82
60/(82+60)=42.3%​

24:

actually one product can be made more than one mole. like 2 Y and one W. but combination of all of them can not make more than 8 carbons. maybe one molecule breaks up in 2Y+W and one breaks up in two Zs. so all combination are correct​

Carbon would be CO with a triple bond, it would require alot of energy and so not possible.

^ someone told me this yest

how does CO become a triple bond?

Carbon to Carbon Monoxide
And Carbon Monoxide will NOT even react with O2 in the air as its quite nonreactive

Idk, i just believed them. :|

don't make me mad, okay? Rules state that ANYONE can report a user who is violating the terms and the violator would be given a warining. on third warning his account will be closed. it was kind of me to tell him about rules than to report him.

Maybe just chill out as he has removed it??

Unreactive cause both C and O has an octate around them not for the triple bond
