Neither. The condensation of oxygen gas is a phase change. The oxygen itself would be an element, not a mixture.
Oxygen is a chemical element not a mixture.
No. It will be a homogeneous mixture of gases.
It is a homogenous mixture
Air in your house is a homogeneous mixture because its components (oxygen, nitrogen, carbon dioxide, etc.) are uniformly distributed throughout the space.
Air is a homogeneous mixture because it is made up of a combination of gases (primarily nitrogen and oxygen) that are evenly distributed throughout the atmosphere. This means that the composition of air is uniform throughout.
Oxygen is a chemical element not a mixture.
An element
Neither, Oxygen is a pure substance not a mixture.
No. It will be a homogeneous mixture of gases.
Neither. Oxygen is an element, which is a pure substance and not a mixture.
It is a homogenous mixture
Smoke is heterogeneous mixture and is easily separable as it's main constituents are Carbon and Oxygen.
Air in your house is a homogeneous mixture because its components (oxygen, nitrogen, carbon dioxide, etc.) are uniformly distributed throughout the space.
No, baking soda is a compound composed of sodium, hydrogen, carbon, and oxygen atoms in a fixed ratio. It is a homogeneous substance, not a heterogeneous mixture.
Pure air is considered a homogeneous mixture because the components of air, such as nitrogen, oxygen, and other gases, are evenly distributed throughout.
Silicon dioxide is a homogeneous mixture, as it is a compound composed of silicon and oxygen atoms uniformly distributed throughout the material.
Water itself is an homogeneous mixture
