when a man named Antoine Laurent Lavoisier wanted to know about the importance of chemical changes. Also‚ in the 19th century‚ John Dalton made the atomic theory. Dalton said that bonding atoms together makes new substances‚ which is a chemical reaction (History of chemical reactions). The definition of chemical reaction is‚ “the processes in which substances undergo chemical changes‚ which results in the formation of new substances.” This is what Dalton and Lavoisier tried to explore (History of chemical

Antoine-Laurent de Lavoisier | Published a textbook that contained a list of elements‚ or substances that could not be broken down further‚ which included oxygen‚nitrogen‚ hydrogen‚ phosphorus‚ mercury‚ zinc‚ and sulfur. It also forms the basis for the modern list of elements. | Johann Wolfgang Döbereiner | Found that some elements formed groups of three with related properties. He termed these groups "triads". In all of the triads‚ the atomic mass of the second element was almost exactly the average

Antoine Lavoisier is credited with the discovery of the Law of Conservation. Lavoisier carried out his ideas as early as 1774. The Law of Conservation has been proven by a variety of experiments. For example‚ if you were to light a candle in completely closed room the mass of the room before l

credit for the discovery. They were both able to produce oxygen by heating mercuric oxide (HgO). Priestley called the gas produced in his experiments ’dephlogisticated air’ and Scheele called his ’fire air’. The name oxygen was created by Antoine Lavoisier who incorrectly believed that oxygen was necessary to form all acids. Oxygen is the third most abundant element in the universe and makes up nearly 21% of the earth’s atmosphere. Oxygen accounts for nearly half of the mass of the earth’s crust‚
