The molecular mass for chlorine is not an integer multiple of the molecular mass of hydrogen but is about 35.5 times the molecular mass of hydrogen. This is primarily because:
a. of the binding energy of the chlorine nucleus. b. there are different isotopes of chlorine. c. the chlorine nucleus has 35.5 nucleons. d. the proton and neutron have different masses.
Name the first three isotopes of hydrogen and their nuclide symbols, and indicate which is most common and which is most unstable

It is easier to significantly alter the earth's CO2 balance than its O2 balance because
A) CO2 is a trace molecule in the atmosphere whereas O2 is not. B) it is so much easier to produce CO2. C) CO2 is a highly reactive molecule whereas O2 is inert. D) CO2 is an inert molecule whereas O2 is highly reactive. E) CO2 is a very unstable molecule whereas O2 is stable.
