4. what is the difference between an acid and a base?
5. What are the 8 properties of water? Why are they important?How do you determine the neutron number given the mass and atomic numbers?
Mass is the number of protons plus neutrons in the nuclues of an atom. Atomic number is the number of protons in the nucleus of an atom. This should help you solve for #1.
The other stuff is pretty basic... it would help if you just read a textbook (if you have been assigned one).
