According to Dalton's law of partial pressures, a mixture of gases inflict pressure in a direct proportion to their volume/mass etc. Therefore, since 79 percent of the air is composed of nitrogen and 21 percent of Oxygen, we multiply 101.3 kPa by 0.79 = 80.027 kPa by Nitrogen, 101.3 kPa by 0.21 = 21.273 kPa by Oxygen.

Answer:
- the electromagnetic spectrum is the range of electromagnetic radiation, organized by how much energy the radiation carries. there is an opposite relationship between wavelength, frequency, and energy. as the wavelength of a wave increases, the frequency and energy decrease, and vice versa.
- the order from longest wavelength (lowest energy) to shortest wavelength (highest energy) is as follows: radio waves, microwaves, infrared waves, visible light waves, ultraviolet waves, x-rays and gamma rays.
Explanation:
hope this helps!
