An element is a substance that is one hundred percent uniformed throughout and includes everything found on the periodic table. A compound is made up of elements that are chemically combined. This means that seperating them requires lots of energy (usually heat). Mixtures are more easy to seperate. Knowing this...
coffee is a mixture
cream (at least ice cream) is a mixture
orange juice is also a mixture...it would stand to reason that lemonade is the same.
(you're on your own for the rest of 'em)
