El flogisto y el oxígeno

The transcript discusses the transition from the phlogiston theory to modern chemistry, highlighting Antoine Lavoisier's role. Initially, the phlogiston theory was widely accepted, but Lavoisier's precise experiments, particularly with tin and mercury oxide, demonstrated that combustion involved oxygen, not phlogiston. This discovery led to the abandonment of the phlogiston theory and the establishment of the modern concept of chemical elements, earning Lavoisier the title of the father of modern chemistry.
