yes, it is.
No - it is an element all in itself. An example of a gas mixture is carbon dioxide, made of a mixture of oxygen and carbon. So helium is just helium; nothing mixed in with it.
A mixture of oxygen and helium is used in diving.
An example of a gaseous homogeneous mixture is air. It is composed of several gases including nitrogen, oxygen, and water vapor and these individual components cannot be easily discerned from their physical properties.
Oxygen is not known as helium. But a mixture of oxygen and helium is used in the oxygen cylinder for underwater diving.
Oxygen is a chemical element not a mixture.
It is homogeneous, but it is not a mixture. It is an element, which is a pure substance.
No - it is an element all in itself. An example of a gas mixture is carbon dioxide, made of a mixture of oxygen and carbon. So helium is just helium; nothing mixed in with it.
A mixture of oxygen and helium is used in diving.
No, It is a chemical compound.
An example of a gaseous homogeneous mixture is air. It is composed of several gases including nitrogen, oxygen, and water vapor and these individual components cannot be easily discerned from their physical properties.
A heterogeneous mixture is a sum of pure substances which are not soluble in each other while a homogeneous mixture is a mixture wherein its constituents do not appear separately. Methanol is an example of a homogeneous mixture.
Oxygen is not known as helium. But a mixture of oxygen and helium is used in the oxygen cylinder for underwater diving.
Oxygen is a chemical element not a mixture.
Neither, Oxygen is a pure substance not a mixture.
An element
All the elements are homogeneous so the oxygen is homogeneous, too.
No. When they make up water they are an example of a molecular compound. Example of homogeneous mixture is air composed of several gasses including Nitrogen (N) Oxygen (O2), Carbon dioxide (CO2), and water vapor (H2O). Another example is sugar dissolved in water.
