Astudent decides to conduct an experiment on a fish bowl that contains a goldfish and a plant. the student decides to remove the fish. assuming that the bowl has a lid and no gases are going into or out of the bowl, describe what will happen to the amount of carbon dioxide and oxygen in the bowl over time.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

it should be briana that has it to me
