Interpretation:
A heating curve must be sketched for mercury.
Concept Introduction:
Heating curve is the graphical representation of the phase change of a substance. Mercury is a metal which is liquid at room temperature.
Answer to Problem 3E
Heating curve of mercury is shown below.
Explanation of Solution
As shown in the heating curve of mercury, melting point of mercury is -38.83°C. At this temperature there is phase change from solid to liquid.
Then temperature is again increased until it reached at 356.7 °C. This is the boiling point of mercury. At this temperature there is phase change from liquid to vapor state.
After this again temperature is increasing.

Thus, it is important to know which atoms carry unshared pairs. Use the structural formulas below to determine the number of unshared pairs at each designated atom. Be sure your answers are consistent with the formal charges on the formulas. CH.
