STEP-BY-STEP EXPLANATION
Firstly, we need to know that the combination of air and argon is a mixture.
Mixture is defined as the combination of two or more constituents that are physically combined together
When a mixture is separated, it is separated into individual constituents and each of the constituents retains its properties.
Recall that Argon is an inert gas and it does not react with any substance.
When argon is separated from the air, it will retain its chemical properties and not the properties of the Argon-Air mixture
