Why is a compound different from a mixture?
Mixture - A physical blend of two or more substances that are NOT chemically combined. Compound - A substance that contains two or more elements CHEMICALLY combined in a fixed proportion. Compound is chemically combined, mixture is not chemically combined. Cake would be a compound because all of the ingredients are together to make batter you cannot see the individual components (eggs, flour, sugar, etc). Trail mix would be a mixture because you can see every individual item (m&m, peanuts, raisins, etc.)
