The air contaminated by the burning of a candle could not support life in a mouse but support life in plants. This experiment was demonstrated by A. PriestleyB. LavoisierC. Von Mayer D.
Neet fusion - In 1770 he performed a series of experiments that showed the essential role of air in the growth of green plants. Priestey discovered O2 in 1774. He experiment with
