Carbon monoxide can affects the body by preventing the hemoglobin in red blood cells from up taking carbon dioxide.

true
false

The answer is false.

When carbon monoxide gets into a persons bloodstream, it does not allow the blood to carry oxygen & as a result it slowly suffocates the person.

the correct option is option d

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.
