“In every combustion there is disengagement of the matter of fire or of light. A body can burn only in pure air [oxygen]. There is no destruction or decomposition of pure air and the increase in weight of the body burnt is exactly equal to the weight of air destroyed or decomposed. The body burnt changes into an acid by addition of the substance that increases its weight. Pure air is a compound of the matter of fire or of light with a base. In combustion the burning body removes the base, which it attracts more strongly than does the matter of heat, which appears as flame, heat and light.”

Antoine Lavoisier
Antoine Lavoisier (August 26, 1743 – May 8, 1794) was a French chemist, widely regarded as the father of modern chemistry. He disproved the phlogiston theory through quantitative experiments, identified the role of oxygen in combustion, and named oxygen and hydrogen. Lavoisier also reformed chemical nomenclature, making chemical language systematic. His book 'Elements of Chemistry' laid the foundation of modern chemistry. However, during the French Revolution, he was executed by guillotine due to his former role as a tax collector. more
