Look, it is not the idea that we do YOUR homework...
So start using your own grey cells by grounding down each item in your list into it's basic contents :
Ask yourself for each of the following : is there more than one single element here ? If more than one element, what is the other, is it a molecule or a mixture (and what type of mixture)...
carbon oxide =
brass =
oxygen =
salt water =
magnesium =
cement =
water =
salad =
Success !
