Ionic substance focus | Chemistry homework help

Looking for some helpful assistance and guidance on the following:

1. From your study of Epsom Salt, state the general properties that are characteristic of an ionic substance. Focus especially on conductivity, melting point and electronegativity differences. Also indicate the kind of elements ( metals or nonmetals) that are combined in an ionic substance.

2. From your investigation of paraffin, state the general properties that are characteristic of a covalent substance. Again, focus on the conductivity, melting point and electronegativity differences. Indicate the kind of elements (metals or nonmetals) are combined in a covalent substance.

3. A. From your data, state what type of bonding (ionic or covalent) sugar must have. Give reasons for
your choice based on the 4 properties you tested.

B. Are there any discrepancies between the observed properties of sugar and the other substance
that appears to have the same type of bonds? If so, what are they?

4. From your data, state what type of bonding (ionic or covalent) salt must have. Give reasons for your choice based on the 4 properties you tested.

5. Using the electronegativity table and the results of the conductivity test, determine which compound, BaF2 or CO2, would conduct the larger electrical current when dissolved in water. Explain your choice.

6. Using the background you have gained from the data table and the electronegativity chart, which substance would you expect to have the lowest melting point – AlBr3, CH4 or MgO ? Explain.

7. Write definitions of the following terms. If needed, you can find definitions in your textbook.

a. solubility

b. conductivity

c. melting point

d. electronegativity
