Answer: d. Glaciers moving revealing bare rock underneath
Explanation:
Primary succession is what happens when living things colonise an area that was previously uncolonized because it had been destroyed or hadn't been created yet.
When glaciers move on from areas and expose the bare rock underneath, these areas are new and so primary succession will take place as living things begin to colonize this new area.
Answer:

<u>Explanation: No. unpaired electrons:</u>
a) square planar, strong field
d⁴ 0
b) tetrahedral, strong field
d⁴ 4
c) Octahedral, weak field
d⁴ 4
d) square planar, weak field
d⁴ 4
e) Octahedral, strong field
d⁴ 2
f) tetrahedral, weak field
d⁴ 4
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
