1.What are the chemicals and their structures that make up cardboard?
2.What are the chemicals and their structures that make up Styrofoam?
3.What are the chemicals and their structures that make up waxes?
4. Explain why water is attracted to cardboard and not Styrofoam?
1. There is no simple way to find out what chemicals make up cardboard, however I had to look at the "base" of the problem. Cardboard is make from paper. The process of making paper includes water and cellulose.

2. The chemicals that make styrofoam include polystyrene, which is a liquid hydrocarbon.

3. Waxes consist of carbohydrates. Carbon, hydrogen and oxygen.

4. Water is attracted to cardboard because cellulose has water in it. Water is made of two hydrogen and 1 oxygen. In cellulose there is 6 carbon, 10 hydrogen, and 5 oxygen. The hydrogen in water is attracted to the oxygen in cellulose, therefore they bond together. Styrofoam is made of polystyrene, 8 carbon and 8 hydrogen. Therefore, water wants to bond with polystyrene, but the chemicals do not bond, because there are no oxygen to bond with hydrogen.
