Sulfur Dioxide(SO2)
The release of SO2 to the atmosphere is the primary cause of acid rain in the world.
Fossil fuel combustion at electric power-generating plants accounts for about70% of
the emissions.
Coal, Oil, and all other fossil fuels naturally
contain some sulfur.
Volcanic eruptions are another more localized natural source of SO2

Solubility :
the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent to form a homogeneous solution of the solute in the solvent.

I first saw the damn thing at that blasted cabin. The Necronomicon. An ancient Sumarrian text, bound in human flesh and inked in human blood. It contained bizarre burial rites, prophesies... and instruction for demon resurrection. It was never meant for the world of the living.

40ml of concentrated sulfuric acid.
Place a thermometer in this nitrating mixture, and then add very slowly 36ml of benzene. after each addition, the contents of the flask thoroughly mixed* This should be added about 3ml at a time,* The temperature of the mixture must not be allowed to rise above 50’C, and should be kept under control if necessary by immersing the flask in cold water.

The crystal structure is a member of the hexagonal crystal system and consists of tetrahedrally coordinated Zinc and Sulfur atoms that are stacked in an ABABAB pattern.
The structure is closely related to the structure of lonsdaleite, or hexagonal diamond.
As there all orientations of the crystal, rings of different 2θ values are formed
