Question

If two compounds that do not react chemically are mixed what do we get

Answer 1

If two compounds that do not react chemically  are mixed then we will not get any new compound or element. They will remain same as they are.

Answer 2

Two components that do not react chemically are mixed:

         If we mix two chemical compounds that do not react with each other then and they will remain as they are in the form they are mixed as a heterogeneous mixture.

         On mixing compounds that don't react with each other sometimes also depends on certain conditions although not being true always, some compounds do not react even under a catalyst or any temperature since they are stable compounds in the way they are and reactions take place only when there is some kind of instability.
