Explanation:

Step1: Analyze \(H_3PO_4\)

• \(H_3PO_4\) (phosphoric acid) is composed of non - metal atoms (\(H\), \(P\), \(O\)). It is a molecular compound as it consists of molecules. Also, it is an acid as it can donate \(H^+\) ions in solution.

Step2: Analyze \(H_3PO_3\)

• \(H_3PO_3\) (phosphorous acid) is made up of non - metal atoms (\(H\), \(P\), \(O\)). It is a molecular compound. And it is an acid because it can release \(H^+\) ions.

Step3: Analyze \(MgBr_2\)

• \(MgBr_2\) is formed from a metal (\(Mg\)) and a non - metal (\(Br\)). Ionic compounds are formed by the transfer of electrons from a metal to a non - metal. So, \(MgBr_2\) is an ionic compound.

Step4: Analyze \(HBr\)

• \(HBr\) is composed of non - metal atoms (\(H\) and \(Br\)). It is a molecular compound. Also, in solution, it can donate \(H^+\) ions, so it is an acid.
