List the utility of oxygen and nitrogen in our lives.
Answers
Answer:
Oxygen makes up around 21 percent of Earth's atmosphere, and, out of the gases found on the planet, humans use it the most, if only because it is necessary for most mammalian life. That said, it finds use in numerous other human endeavors: medicine, construction, transportation and even recreation, to name a few. Swedish chemist Carl Wilhelm discovered the tasteless, odorless gas in 1772 after he experimented, heating different oxygen-containing compounds. While oxygen makes up a good portion of Earth's atmosphere, Earth's crust contains large amounts of it in solid form as various oxides, and the world's oceans contain an abundance of it as H2O, also known as dihydrogen monoxide or water. Oxygen makes up 46 percent of Earth's crust and stands as the most plentiful element in the structure, and it makes up 89 percent of the world's seawater.
Answer:
Oxygen is used by animals and plants in the respiration (breathing) process. Tanks of oxygen are used in medicine to treat people with breathing problems. They are also used as life support for astronauts and scuba divers. The majority of the oxygen used in industry is used in the manufacturing of steel.
It is also used in various industries. For example, in the chemical industry is used to make fertilizers, nitric acid, nylon, dyes and explosives. For making these products, it is imperative for nitrogen to react with hydrogen to produce ammonia. Here are the five applications of nitrogen in everyday life.
