Is it you that has been making that acid rain? Please desist.

Explanation:

Acid rain derives from the dulfur dioxide that is produced by the combustion of sulfur-rich coal:

#S(s)+O_2(g)rarrSO_2(g)#

And sulfur dioxide is the acid anhydride of sulfurous acid:

#SO_2(g) + H_2O(g) rarr H_2SO_3(g)#

Of couse, under some circumstances, sulfur dioxide could be oxidized up to #SO_3#, which is the acid anhydride of sulfuric acid,

#SO_3(g) + H_2O(l) rarr H_2SO_4(aq)#
