1. Addition of ethyl alcohol to acetic acid in the presence of conc. H2SO4:
Ethyl Alcohol reacts with Acetic acid in the presence of Conc. H2SO4 at high tempertaure to form a sweet smelling Compound called as Ethyl acetate ester and this reation is known as esterifiation precess.
C2H5OH + CH3COOH ----->CH3COOC2H5 +H2O
2)Burning of Ammonia in Air.
Ammonia is not a supporter of combustion, it does not burn in air. It stops the burning splinter.
3) Action of Dil.HCl on iron (II) Sulphide.
Dil. HCl decomposes Iron (II) sulphide to produce iron (II) chloride and hydrogen sulphide having rotten egg smell.
FeS +2HCl ------>FeCl2 +H2S.
