What is the same between compounds and mixtures?

Compounds are chemically mixed. You can't see the ingredients, elements, etc. in compounds. Compounds make a new thing. Compounds can't be separted easily. Compounds can't contain mixtures. Mixtures are not chemically mixed. You can see the ingredients, elements, etc. in the mixture. Mixtures don't create anything new. Mixtures can be separated easliy. Mixtures can contain compounds. Both mixtures and compounds are mixes of things. Both mixtures and compounds contain 2 or more elements, ingredients, etc. Hope I helped!
