Explanation:
Depending on amount added, Anhydrous CaCl₂ when dissolved in water solvent can become hot enough to blister ones skin when touched. On the cold side, Ammonium Nitrate will cool an aqueous solution enough to generate condensate frost on the outside of a glass beaker. I'm sure there are more examples but these two came to mind.
<span>To account for the hexavalency in SF6 one electron each from 3s and 3p orbitals is promoted to 3d orbitals as shown in fig.1.27(b). These six orbitals get hybridised to form six sp3d2hybrid orbitals. Each of these sp3d2 hybrid orbitals overlaps with 2p orbital of fluorine to form S-F bond.
The answer is S(sp3d2)- F(p)</span>
