Is Oxygen A Pure Substance
Is oxygen a pure substance or a mixture?
Pure substances cannot be separated into other substances. Some examples are carbon, iron, water, sugar, salt, nitrogen and oxygen. So you have a pure substance. Otherwise you have a mix.
Is oxygen a substance or a mixture in this sense?
The compounds themselves cannot be a mixture. A blend contains more than one compound. O2 is just elemental oxygen. It is a pure substance, not necessarily because it only contains oxygen atoms, but because there are only oxygen molecules.
Is air also a pure substance or a mixture?
Answer and explanation: Air is not a pure substance because it is a homogeneous mixture of different substances.
Air is a homogeneous mixture because the air is completeIs oxygen also a pure substance or a compound?
Contains: Lead (Pb) element Lead atoms Gaseous oxygen (O2) element Oxygen molecules * Water (H2O) partner Water molecules ammonia (NH3) partner Molecules of ammonia Are mixtures pure substances?
Substances can be divided into two categories: pure substances and mixtures. The pure substances are then broken down into elements and compounds. Mixtures are physically combined structures that can be broken down into the original components. A chemical is made up of some type of atom or molecule.

Is oxygen a heterogeneous mixture?
The mixtures can be homogeneous or heterogeneous. An example of a mixture is air. Air is a homogeneous mixture of gaseous substances, nitrogen, oxygen and small quantities of other substances. Salt, sugar and many other substances are dissolved in water to form homogeneous doughs.
