A group of students performed a melting point experiment to study the physical properties of ionic and covalent solids. The data collected are shown in the table.
Solid Sample
Melting Point (oC)
Time Elapsed (min)
Table Sugar (sucrose)
186

Table Salt (sodium chloride)
500 (not observed)
30
Paraffin Wax
37
4
Vegetable Lard

>5
Using the information contained in the table, what is the BEST explanation for the results?A The melting point of sodium chloride was not observed because ionic solids do not melt, whereas sugar, wax, and lard melted because they are softer than salt.B The melting points of covalently bonded solids tend to be lower than ionic solids. The melting point of sucrose was greater than the wax or the lard because sucrose has stronger bonds than wax or lard.C The melting point of sodium chloride was not observed because ionic solids are composed of positive and negative ions that do not melt; whereas, the…
