Question

1- The main classes of solids we will be testing are thefollowing: ionic, covalent network, metallic, and molecular.

Rank the general trend for these classes from lowest mpto highest.

( ) <( ) < ( ) < ( )

2. What is the general trend of how the classes dissolve?

• ionic = [ Select ] ["rarelydissolves", "dissolves only in nonpolar solvents", "dissolves onlyin polar solvents", "may dissolve in nonpolar or polar solvents"]
• covalent network = [ Select ] ["rarelydissolves", "dissolves only in nonpolar solvents", "dissolves onlyin polar solvents", "may dissolve in nonpolar or polar solvents"]
• metallic = [ Select ] ["rarelydissolves", "dissolves only in nonpolar solvents", "dissolves onlyin polar solvents", "may dissolve in nonpolar or polar solvents"]
• molecular = [ Select ] ["rarelydissolves", "dissolves only in nonpolar solvents", "dissolves onlyin polar solvents", "may dissolve in nopolar or polar solvents"]

3 - What is the general electrical conductivity trend of theclasses?

• ionic: [Select ] ["rarely conducts","conducts well when dissolved", "conducts well as a solid"]
• covalent network: [ Select ] ["rarelyconducts", "conducts well when dissolved", "conducts well as asolid"]
• metallic: [ Select ] ["rarelyconducts", "conducts well when dissolved", "conducts well as asolid"]
• molecular: [ Select ] ["rarelyconducts", "conducts well when dissolved", "conducts well as asolid"]
