What does "like dissolves like" mean

What is the salt that is produced when ammonia (NH3) and hydrochloric acid (HCl) react together? NCl NH4 + NH4Cl NH2Cl

Find ΔH for: BaCO3 (s) → BaO (s) + CO2 (g) given 2 Ba (s) + O2 (g) → 2 BaO (s) ΔH = - 1107.0 kJ Ba (s) + CO2 (g) + ½ O2 (g) → BaCO3 (s) ΔH = - 822.5 kJ
