Answer:
I think its A maybe am not sure
Here...see the attachment
Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO 3) than the organic is a sedimentary rock composed largely of the minerals calcite and araganite.
Structure 1 is satisfying octet rule because each atom surrounded by 8 electrons:
The valance electron for oxygen is 6, for sulfur is 6, but for hydrogen is 1. Therefore, the molecule has <span>valance electrons. Sulfur is bonded with 4 oxygen atoms, 4 single bonds, whereas 2 hydrogen atoms are bonded with 2 oxygen atoms.
But the actual structure is 2 but it violates octet rule since S is surrounded in this case with 12 electrons
