What did Lavoisier find out about oxygen that was so important?
Lavoisier is most noted for his discovery of the role oxygen plays in combustion. He recognized and named oxygen (1778) and hydrogen (1783), and opposed the phlogiston theory. Lavoisier helped construct the metric system, wrote the first extensive list of elements, and helped to reform chemical nomenclature.
How did Lavoisier give oxygen its name?
In 1774 Joseph Priestley visited Paris. He told Lavoisier about the gas produced when he decomposed the compound we now called mercury oxide. In 1779 Lavoisier coined the name oxygen for the element released by mercury oxide. He found oxygen made up 20 percent of air and was vital for combustion and respiration.
How is oxygen generated?
One is by liquifying air through a process called cryogenic distillation. In this method, oxygen is produced in air separation plants where the air is cooled and the oxygen is distilled based on its boiling point. Oxygen can also be generated from the air itself by a machine called an oxygen concentrator.
Which country produces the most oxygen?

How do hospitals make oxygen?
Oxygen is made in two ways: – Medical oxygen: is made by separating the oxygen from other gases and impurities found in air by repeated steps of compression, filtration and purification, according to Air Liquide Sante France. Such medical oxygen reaches more than 99.5 percent purity and is rigorously tested.

How can I increase oxygen in my house?
Adding plants such as the areca palm, snake plant, money plant, gerbera daisy or Chinese evergreens can actually increase the oxygen in your home naturally. Try adding natural air purifiers such as salt lamps, beeswax candles, peace lily and bamboo charcoal to help keep the air in your home cleaner.
How can I get more oxygen in my sleep?

- Regular exercise to stimulate your respiratory system and improve lung capacity.
- Adjust your sleep position; sleeping on your side can alleviate the weight on your lungs and improve respiration.
- Avoid alcohol near bedtime.
