soapy water: mixture hydrogen gas: pure substance sodium chloride: pure substance* It's not fully pure originally (not on the periodic table) you need to bond two pure substances together to obtain it. Sep 08 05, 8:11 PM

Classify each of the following as an element or a compound: potassium carbonate, water, and Mg? I have a container which originally held 500 grams of what the label claims to be "finest table salt" - pretty much pure sodium chloride. Yet, out of every 100 grams in the container, only 39 grams are sodium. Since a molecule of table salt is made up of an equal number of sodium and chlorine atoms, this leads me to believe that chlorine is a much heavier element than sodium. Is that really true? Would you classify Cuba as part of Latin-America, or is the Caribbean a completely seperate region? Hydrogen gas exists as H2 rather then H. Why is this so?
