A mixture ( it contains lots of gases.)
It is a mixture of all the gasses in the atmosphere and water.
The pure nitrogen is a chemical element, gaseous at room temperature.
Element: oxygen, potassium Compound: sodium chloride, potassium dichromate Mixture: air, orange juice
Iron is an element NOT a mixture.
Air is a mixture of several gaseous elements, such as oxygen and nitrogen, and compounds, such as carbon dioxide. In the sense of the four elements, water, fire, earth, and air, air is an element.
Air is not. It is often confused as being Oxygen, which is an element. The air we breath is made up of Oxygen and Nitrogen. So, it is made up of elements.
Air is a mixture of gases.
Homogeneous mixture-uniform mixture of the element
It is a mixture of gases.
Air is a mixture, made mostly of the elements nitrogen and oxygen. It also has some other gases, such as argon (element), carbon dioxide (compound), and water (compound).
Air is mostly composed of elemental substances or molecules. It is also called as a mixture of compounds and elements.Air is not a compound, but it isn't a particular element. Air is a mixture of gasses that do not react with each other.
Oxygen is an element and so can not be a mixture by itself. It can be part of a mixture, for example in air.
It is a mixture of all the gasses in the atmosphere and water.
The pure nitrogen is a chemical element, gaseous at room temperature.
Air (clean or dirty) is a mixture, as it contains several different gases.
Air is not an element. It is a mixture of gases. It's principal components are are nitrogen (~79%), oxygen (~21%), carbon dioxide (<0.1%) and argon.
because there are many elements and compounds in that make it up, eg, CO2 is a compound, but O2 is an element. This means its a mixture not an element.
