The melting point of a solid compound is reported as a range of two temperatures. For example, the literature (known) melting point of benzamide is 125-128 °C.

a.What does the first temperature in this range indicate?

b.What does the last temperature in this range indicate?

1. An experimental melting point is always reported as a range of temperatures (for example 171-174˚C). A student observed the following while taking a melting point: “The sample started shrinking at 93˚C. At 95˚C some liquid appeared. By 97˚C, the sample was a pool of liquid with a chunk of solid suspended in it. The suspended solid continued turning into liquid, becoming completely liquid at 98˚C”. a)What should the student report as the melting point? b) What two types of...

When 27.2 g of solid A, at its melting point of 34.0 °C, was added to 62.7 g of liquid A at 51.2 °C, the mixture cooled to 35.0 °C, with no solid remaining. Given the specific heat of liquid A (s = 0.798 J/g·°C), find the heat of fusion per gram of solid A. Assume that no heat enters or leaves the mixture. That is, assume that the mixture is an isolated system and therefore that q1 + q2...
