Air is not pure due to the presence of various pollutants and particulate matter from sources such as industrial emissions, vehicle exhaust, construction activities, and natural phenomena like wildfires and dust storms. These contaminants can include gases like carbon monoxide and sulfur dioxide, as well as particulate matter like soot and pollen. Additionally, human activities contribute to the accumulation of greenhouse gases, which further degrade air quality. As a result, the atmosphere often contains a mixture of harmful substances that can affect health and the environment.
Pure air is homogeneous because all components are completely miscible.
Pure mountain air is not a pure chemical substance, but rather a mixture of various gases including nitrogen, oxygen, carbon dioxide, and others. The composition of mountain air can vary depending on factors such as elevation and surrounding pollution levels.
How could a man as such have pure tolerance? She was not as pure as a rose. Bill was as white as a pure albino.
homogeneous
burns faster in pure oxygen as the percentage of oxygen is less in air
reason for air is not pure
air is not pure
A pure air can be prepared only in laboratory, by mixing the components. Note that air is not a compound but a mixture of gases. In the nature pure air don't exist - the air is polluted.
No. Air is not pure substance. Air has all dust and dangerous gases with it. From place to place its composition changes.
Pure air is homogeneous because all components are completely miscible.
No
No, there is 21% oxygen in air.
As per my knowledge pure substance does not have anything else added to it. Air and water are pure substances that exist in nature. A pure substance cannot be taken apart to locate more substances.
Air is a mixture.
pure air is homogeneous but dusty air is heterogeneous
The ultrapure water is not conductive.
Sodium and iron are pure elements, while sugar and oxygen are pure compounds. Air, on the other hand, is a mixture of gases and not a pure compound.
