Oxygen gas can also be produced through electrolysis of water into molecular oxygen and hydrogen. DC electricity must be used: if AC is used, the gases in each limb consist of hydrogen and oxygen in the explosive ratio 2:1. A similar method is the electrocatalytic O 2 evolution from oxides and oxoacids.
29 lip 2024 · Nitrogen gas is the primary component of air. Nitrogen, oxygen, water vapor, argon, and carbon dioxide account for about 99% of the composition of air. Trace gases in Earth's atmosphere include neon, methane, helium, krypton, hydrogen, xenon, ozone, and many other elements and compounds.
1 lut 2021 · About 99% of the composition of air consists of nitrogen, oxygen, and argon. Water vapor (variable) and carbon dioxide are the main trace gases. There is no chemical formula for air because the Earth’s atmosphere consists of a mixture of gases.
The molar mass of dry air with oxygen, nitrogen and the other components as indicated below is 28.9647 g/mol. Composition and content of each gas in air is given in the figures and the table below.
