nid404:
lol...heat doesn't go away...it's just spread over a larger volume. You tell me will a larger volume of water heat faster or a lower volume?
really...then maybe i got the question wrong. If you understood the answer for h, i won't have to go through the whole thing again...lol...sorry...it's just that im doing mechanics alongside...
+rep not really required..but thanks..lol
WARRIOR:
hehe thanks :D and mechanic :o :o :o :o :o goodluck
and last thing :P
Another questionS
Does NaOH prod. more heat with H2SO4 than wth HCL?
Does Group 1 and group 2 form colourless solution ?
cz i saw an analysis question..A CALCIUM SALT ( solutrion ) : COLOURLESS . i wrote white..
Why as u increase the length of an alcohol chain you do not need to burn as much fuel to release the same amoutn of energy?
ill dissapear after this
nid404:
All neutralization reaction have the same energy released...-57KJ/mol
colorless solutions...?? like what as hydroxides, salts..if salts...which salts.?? calcium carbonate is insoluble
And to your last question...well...i didn't quite get what ur asking...cause does this mean there are more OH groups..or only the no of hydrocarbons increased?
lol u needn't disappear...someone will always help you out here
WARRIOR:
1.ok thats very helpful ..all neut haev same energy release! new fact
anyway
2.yea true ..stupid question from me..not concentrating..hmm i must have read the questing in a wrong way ...nvm
3 u kno the experiment to check which alcohols gives out more energy?
where you put the alcohols in a spirti burner..then heat the water in a copper can to a specific temperature.. and then weigh the masses of the spirit burner. etc..
WARRIOR:
it says ..solution C has a calcium salt .identify the colour of solution C
does solution mean its colourless?
