Explanation:

Ionic compounds are typically formed between a metal and a non - metal. In the first set, Fe (iron) in FeCl₃ is a metal and Cl (chlorine) is a non - metal. In the second set, Ca (calcium) in CaCl₂ is a metal and Cl is a non - metal. The other options in both sets are made up of non - metals only and form covalent compounds.

Answer:

For the first question: B. FeCl₃
For the second question: A. CaCl₂
