carbon dioxide, and oxigen
Hydrogen and helium were the two primary gases present during the formation of our solar system. These gases dominated the early solar nebula from which the Sun and the planets eventually condensed.
Nitrogen and oxygen are two of the primary gases that make up air. The third is argon.
The two main gases are Nitrogen (N2) and Oxygen (O2), which comprise around 78% and 21% of the atmosphere by volume respectively. The remaining 1% is mostly Argon (Ar), followed by Carbon Dioxide (CO2) as well as several other gases present in trace amounts. All of these figures are for dry air, however water vapour (H2O) is also present in air at levels of up to 4%, but this is highly variable depending on localised conditions, and it makes up a lower percentage of the atmosphere as a whole.
The two unreactive gases in the air are nitrogen (about 78%) and oxygen (about 21%).
Nitrogen and Oxygen are the most common gases in the atmosphere.
Two elements found in unpolluted air are nitrogen, which makes up about 78% of the atmosphere, and oxygen, which makes up about 21%. These two elements are crucial for supporting life on Earth.
Carbon Dioxide is present in unpolluted air. Methane (animals grazing literally fart this out) is also present and Nitrogen oxides formed when lighting strikes. The electrical discharge is high enough to cause oxygen and nitrogen to combine. It is basically a natural fertilizer In unpolluted air these compounds are present at levels of about 390 parts per million, 1.8 parts per million, and 1 part per billion respectively. The most abundant and most important compound in unpolluted air is ... water vapour -- present at levels which vary between about 0.1% and 5%, depending on temperature and humidity.
Oxygen and nitrogen are two main elements found in unpolluted air. Oxygen is needed for respiration by humans and animals, while nitrogen makes up the largest portion of the Earth's atmosphere and is essential for plant growth.
Aside from bubbles, there is no "air" in water, however oxygen and other atmospheric gases, such as oxygen or nitrogen, may readily absorb into water. Water is after all made up of two atmospheric gases, hydrogen and oxygen.
The two most abundant gases on Earth are nitrogen and oxygen.
particles and gases
Hydrogen & carbon dioxide.
There are not two gases in the layer but one. Ozone is the only gas present in the ozone layer.
Air is a mixture and not a compound because of the following reasons: Air can be separated into its constituents such as oxygen, nitrogen etc. by fractional distillation of liquid air. Air shows the properties of all the gases present in it.
