Discuss the relationship of carbon dioxide and oxygen. Explain how it remains Balanced. What has man done to upset this natural relationship?​

Power plants

Explanation: They release the waste from it into the air

Explanation: the primary function of the respiratory system is to take in oxygen and eliminate carbon dioxide

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.
