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..

Discovery
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 Antoin..

Discovery of Oxygen
Two scientists, Carl Scheele of Sweden and Joseph Priestly of England working independently, discovered oxygen. They published their discovery in 1777. Scheele obtained oxygen by heating potassium nitrate and mercuric oxide and called it "Fire Air". Priestley called it "Dephlogisticated Air". ..

: an active part, and an inactive part. This discovery was made by John Mayow in 1674. In 1789, Antoine Lavoisier found out that the active and the inactive parts were in the proportion of 1:4 by volume. The active part was later named oxygen, and the inactive part, nitrogen. ..
