    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 !
