You can determine which is the acid and which is the base from the Bronsted-Lowry definition of a base an acid. According to Bronsted-Lowry, an acid is a species that donates a proton (H+) and since HI has a H in it, it is the only one of those species that can donate an H+ via breaking the H-I bond. According to Bronsted-Lowry, a base is a species that can accept a proton, CaO can do this by breaking the Ca-O bond and then 2 H+s bind to the O2- to make water.
