Air is composed of more than 2 gases:
78% Nitrogen
21% Oxygen
1% of other gases lime Carbon Dioxide, Ozone, Argon etc.
1. Nitrogen - cca. 78 % 2. Oxygen - cca. 21 % 3. Argon - cca. 1 %
The two main types of main fronts are warm fronts and cold fronts. Warm fronts occur when warm air advances and rises over cold air, leading to gradual weather changes. Cold fronts form when cold air advances and lifts over warm air, causing rapid weather changes, such as thunderstorms.
Hydrogen and Nitrogen. Or oxygen and carbon dioxide, or carbon monoxide.
The two main causes of air pollution are emissions from vehicles and industrial activities. These sources release pollutants like carbon monoxide, nitrogen oxides, and particulate matter into the air, contributing to poor air quality and adverse health effects.
Two main human sources of primary air pollutants are industrial activities, such as burning fossil fuels and manufacturing processes, and vehicle emissions from transportation including cars, trucks, and planes.
hydrogen and helium
Particles and Gasses
The two unreactive gases in the air are nitrogen (about 78%) and oxygen (about 21%).
Hydrogen and helium are the two main gases that make up the Sun. Hydrogen is the primary component, making up about 75% of its mass, while helium accounts for most of the remaining mass.
Oxygen and nitrogen - 80% nitrogen and 19% oxygen. :)
There are two main gasses that are exchanged in the lungs: carbon dioxide and oxygen. The lungs use tiny air chambers called alveoli to take in oxygen and let out carbon dioxide.
oxygen and nitrogen
The air we breathe contains 78% Nitrogen and 20% Oxygen. The remainder is Helium and other gases
Nitrogen and oxygen.
Gases in air are nitrogen about 79%, oxygen about 20% and other gases 1%
Nitrogen and oxygen are two of the primary gases that make up air. The third is argon.
No. Air is an example of a mixture of gasses. Brass is an example of a mixture of two solid metals.
