Document Summary

Chapter 1 keys to the study of chemistry. 1. 2 chemical arts and the origins of modern chemistry. New theory triumphed b/c it relied on quantitative, reproducible measurements, not on strange properties of undetectable substances. Many propose that the science of chemistry began with lavoisier. left 4/5 of the air remaining: a burning candle placed in the remaining air was extinguished. Lavoisier named the gas oxygen and gave metal calxes the name metal oxides. His explanation of his results made the phlogiston theory irrelevant: Oxygen, a normal component of air, combines with a substance when it burns. In a closed container, a combustible substance stops burning when it has combined with all available oxygen.
