Answer:
Below -38*C Mercury will freeze. Above 350*C Mercury will begin to boil.
Explanation:
Each element has different boiling and freezing points. For mercury this is these set constraints.
The substance that would be least likely to dissolve in a polar solvent IS A NON POLAR MOLECULE.
Examples of non polar molecules are oil and cholesterol. These molecules are non polar, that is, their electrons are distributed evenly throughout the element and thus their charges cancel out one another. Such compounds will not dissolve in polar solvent.
They don't react with other elements under normal conditions as they are already in a low energy or stable state
