--- End quote ---

ethanoic acid is used as a preservative and flavouring.
carboxylic acids are made by the oxidation of alcohols

so they r the same!
cuz alchohols oxidize 2 form ethanoic acids

--- End quote ---

The temp would fall, this is because it takes more energy/heat to break the bonds between the atoms, if it was exothermic, then more energy would be used to form new bonds, and the temp. raises

--- End quote ---

correct me if im wrong but i thought it was the other way round
cuz endo takes in heat so temp rises(positive)
and exo gives out heat go temp falls(negative)

Ghost Of Highbury:
exo...is one a substance gives out heat...therefor the temp. of the surroundings rise..

vive versa for endo
