1 Which of the following involves an increase in entropy (randomness)?
life (as opposed to death)
condensation reactions
polymerization processes
a cube of salt dissolving in water
2 What is the bond type between water molecules?
polar covalent bond
Hydrogen bond
ionic bond
nonpolar covalent bond
3 Which of the following provides evidence for the decrease in density that occurs when liquid
water freezes to form ice?
Salt dissolves in hot water faster than in cold water.
Small bodies of water like ponds and lakes freeze from the top
down. It takes a really long time for water to boil.
Water alone isn't very good at removing bacon grease from dirty dishes.

8 : If an atom has a charge of +2, which of the following MUST be true?
It has two more protons than neutrons.
It has two more electrons than protons.
It has two more protons than electrons.
It has two more neutrons than
electrons.
9 Atoms that participate in covalent bonds exhibit a property called "electronegativity," which is a
measure of how strongly their positivelycharged nuclei attract the shared electrons in the bond.
A polar covalent bond is formed when one of the atoms involved in the bond has a much higher
