Calcium oxide - Wikipedia
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound.It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term "lime" connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate.

Chemistry: The Central Science, Chapter 3, Section 2
In fact, the example given in Equation 3.10 involves CaCO 3, which decomposes to form CaO and CO 2. Thus, we would suspect that BaCO 3 decomposes to form BaO and CO 2 . The fact that barium and calcium are both in the same group in the periodic table, group 2A, further supports the idea that they would react in the same way:
