Classify the following materials as pure substances or mixtures: powdered sulfur, 80 proof vodka, baking powder. If they are mixtures, subclassify them as homogeneous or heterogeneous; if they are substances, subclassify them as compounds or elements.
Powdered sulphur is a pure substance because it's composition is fixed and also it is a element because it is made up of one element only.
80 proof vodka is mixture because it's composition is not fixed and it is homogeneous mixture because composition is uniform through mixture.
Baking powder is pure substance because composition is fixed and it is compound because it is made up of more than one atoms.
