Answer to Question 1

A free radical is an atom or molecule which has at least one electron which is not paired with another electron. It is so reactive because the natural state of matter is for that unpaired electron to form a bond.

Answer to Question 2

Nylon is made through the condensation polymerization process. Water is a byproduct of the polymerization. After a certain point in the process, the reaction begins to slow because of the abundance of water. Continued reaction becomes increasingly more difficult and chain growth is halted. This gives shorter chain length and lower molecular weight. One method to overcome the overabundance of water in the reaction vessel is to apply a vacuum to the polymerization chamber. By removing the water from the reaction, the molecular weight can continue to grow.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.

A good example of polar molecules can be understood when trying to make a cake. If water and oil are required, they will not mix together. If you put them into a measuring cup, the oil will rise to the top while the water remains on the bottom.
