It is homogeneous, but it is not a mixture. It is an element, which is a pure substance.
No, nitrogen and oxygen are not a homogeneous mixture. They are two separate gases that can exist in the air as a uniform mixture.
A homogeneous mixture
Neither. Oxygen is an element, which is a pure substance and not a mixture.
No, a sulfuric acid solution in water is homogeneous
Air, like other phases that contain only gas, is usually a homogeneous mixture. If the air contains solid particulates, such as soot, or liquid particulates, such as rain drops, the air is a heterogeneous mixture.
An element
Liquefied air is a homogeneous mixture because it is a single phase solution where the components (nitrogen and oxygen) are uniformly distributed throughout the liquid.
No, nitrogen and oxygen are not a homogeneous mixture. They are two separate gases that can exist in the air as a uniform mixture.
Homogeneous, and sometimes also a solution.
The mixture is homogeneous only when these liquids are miscible.
A homogeneous mixture
All the elements are homogeneous so the oxygen is homogeneous, too.
Liquid gold-homogeneous Solid-heterogenous
Neither. Oxygen is an element, which is a pure substance and not a mixture.
solution
Yes.
Oxygen is a chemical element not a mixture.
