discuss in brief the type of adsorption isotherm commonly observed for the adsorption of gases on a variety of adsorbent at different temperature

Mgo2 is the oxidation state of manganese oxide

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

It has to be b i hope this

And a) oxygen i believe
