Another component of acid rain is nitric acid, which forms when NO2, also a pollutant, reacts with oxygen and water according to the simplified equation:

4 NO2(g) + O2(g) + 2 H2O(l) > 4 HNO3(aq)

The generation of the electricity used by a medium-sized home produces about 16 g of NO2 per year. Assuming that there is adequate O2 and H2O, what mass of HNO3, in g, can form from this amount of NO2 pollutant?

i'm wiling to try and you : )

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
