Co2 concentrations in the atmosphere are stable around 408 ppm (parts per million), which translates to approximately 1016 molecules cm-3 . what is the mass concentration of co2 in units of μg m-3 ? given the annual rate of increase of co2 of 1.6 ppm yr-1 , what is the projected co2 concentration in 2100 in units of ‘ppm’ and ‘μg m-3 ’? hint: assume an air density of 2.4×1019 molecules cm-3 .

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
