No... u don't need to know it... he probably made u draw it to explain u or something. I mean, i did AS Chem two times, i ddnt come across this at allummm really?? bcz our sir made us write it down... drat if we don't need it btw
yeah its ryt..okay question: - give me the formula of Tollen's reagent
it is [Al(NH3)2]+ ??
I love biology... i relate almost everything to bio... sometimes, i even tend to describe a place the way the cytoplasm is in the palisade mesophyllI kind of like Bio. It's a cool subject, interesting and all, but terribly long.
thanks Mustafa was just having some confusionsyeah its ryt..
its Ag(NH3)2OH
anytimethanks Mustafa was just having some confusions
plz someone give me a reaction of carboxylic acid with carbonates
syed1995
CH3COOH + NA2CO3 -> CH3COO-Na+ + CO2 + H2O. And now im going to be moving to the AS thread or making an A2 thread for the next paper. Goodnight and good luck to you all, please do remember me in your prayers!plz someone give me a reaction of carboxylic acid with carbonates

soorry to burst ur bubble friend but its Na2CO3HCOOH + NaCO3 --> HCOONa + CO2 + H2O
its not balanced :OCH3COOH + NA2CO3 -> CH3COO-Na+ + CO2 + H2O. And now im going to be moving to the AS thread or making an A2 thread for the next paper. Goodnight and good luck to you all, please do remember me in your prayers!
soorry to burst ur bubble friend but its Na2CO3
I think H+ ion is just a condition for esterification rather than reagent ... however am not sure in Chem as much I m in mathsIn esterification we have to heat with reflux and use H2SO4 as a reagent right?? syed1995 and MustafaMotani
its not balanced :O
