Question

Which of the following form solid solutions? Select all that apply.

naturally occurring minerals
gases present in air
HCl and water
sugar and water
metal alloys

Answer 1

naturally occurring minerals

metal alloys

Step-by-step explanation:

Answer 2

I believe the answer is
naturally occurring minerals
metal alloys

The metal alloy is a solid solution that made of metal and other elements.
The example of an alloy is bronze, which is made of copper mixed with nickel, aluminum, zinc or manganese. Most minerals should form a solid solution too, but not all of them.Gases present in air is not solid at all. A solution of HCl and sugar will not form solid solution either.
