problem 2
diamond is composed of carbon atoms covalently bonded together in a network structure.

Explanation:

• Salt: Potassium iodide ($KI$) is an ionic compound formed from the reaction of a base (potassium hydroxide, $KOH$) and an acid (hydroiodic acid, $HI$), which is a characteristic of a salt.
• Compound: It is made up of two different elements (potassium and iodine) chemically combined in a fixed ratio.
• Chemical: A chemical is any substance that has a defined composition, and potassium iodide fits this description.
• Not a molecule: Molecules are formed by covalent bonding where atoms share electrons. Potassium iodide has ionic bonding (transfer of electrons from potassium to iodine), so it does not exist as discrete molecules in the solid - state (it forms a lattice structure).

Answer:

B. salt, C. compound, D. chemical
