lavoisier

A.L.Lavoisier and P.S.Laplace gave this law in 1780 which states that 'the enthalpy of a reaction is exactly equal but opposite in sign for the reverse reaction'. For example, if D H is the enthalpy change in going from A to B then the enthalpy change for the process B to A would be - D..

Acids, bases and salts are three main categories of chemical compounds. These have certain definite properties that distinguish one class from the other. Scientists like Lavoisier and Davy studied acids and bases in a scientific manner. Initially, Lavoisier believed oxygen..

Daniel Rutherford, a Scottish Physician, discovered nitrogen in 1772. But it was Lavoisier, who proved that nitrogen is an element and that it was not a supporter of combustion and respiration. He called it 'azote' meaning 'no life'. The name 'Nitrogen' was given to it by Jean Antoi..

Johann Glauber (1604-1668) prepared nitric acid by heating nitre with concentrated sulphuric acid and then condensing the vapour. While Henry Cavendish determined the composition of nitric acid, Lavoisier proved that oxygen is present in nitric aci..
