Answer:

1. False.

2. True.

3. True.

4. True.

5. True.

Explanation:

1. The compound would be expected to have a relatively low melting point. FALSE. MgCl₂ is a salt. Salts usually have a high melting point

2. The compound is ionic. TRUE. If difference of electronegativity for Mg and Cl is larger than 1,7 the compound is ionic. Mg has an electronegativity of 1,2 and Cl has an electronegativity of 3,0 giving an electronegativity difference of 1,8.

3.The compound is molecular. TRUE. When you have a combination of two ore more atoms you will have a molecule. In this case you have 1 Mg and 2 Cl.

4. If the compound dissolved in water it would be a strong electrolyte. TRUE. An ionic salt as MgCl₂ will be a strong electrolyte in water.

5. The compound would conduct electricity if molten. TRUE. Ionics compounds conduct electricity when molten.

I hope it helps!
