TRUE OR FALSE, if false then give the correct word to make the statement true then explain 1. Sublimation occurs when a solid has a relatively high vapor pressure at a temperature [above] its melting point. 2. To isolate the desired chemical, a single extraction is [more efficient] than extracting the compound numerous times. 3. The compounds are separated in liquid-liquid extraction based on their relative solubilities in two [immiscible] liquids.

3. A pure white crystalline compound was found to melt at 131.5-132.0°C when taken on a melting point apparatus, and on further heating, the liquid was found to start bubbling at ca. 155-160 °C. The capillary containing the melted compound was set aside to cool, and resolidify. When the sample was retried using that same capillary, the sample melted at 120.6-154.5°C, along with some bubbling. What is the cause of the bubbles? Why is the melting point so wide the second time? Explain by stating what you have learned in this laboratory about melting points.
