<span>They can be separated by physical processes.
This problem requires you to simply memorize the definition of a mixture. So let's take a look at the choices and see why one is correct while the other three are wrong.
1. They are chemically bonded together - The definition of a mixture is where "two or more pure substances are combined where each substance retains its individual chemical property." This option isn't correct.
2. They can be classified as pure substances - This option doesn't work either since a mixture has two or more pure substances.
3. They have fixed ratios between their components - Imagine a mixture of salt and flour. You can have a little salt in the mixture or a lot of salt in the mixture. There isn't a fixed ratio, so this is also a bad choice.
4. They can be separated by physical processes - Since the other three options are all obviously false, this is the only possible option. Mind, the separation may not be easy (take a look at the salt and flour mixture used as a demonstration above), but it should be possible.</span>
