Barium oxide was synthesized form the reaction of barium and oxygen in a crucible according to the balanced chemical reaction below. Water
was used to convert any side products to Bao, and then the crucible was heated to drive off any remaining moisture. The mass data from the
experiment is shown below.
2 Ba(s) + O2(g) → 2 Bao(s)
