A hydrated barium hydroxide compound is heated to remove all the water of hydration. The mass of the compound before heating was 15.6 g and after heating the mass was recorded as 8.75 g. a) Determine the chemical formula of the hydrate. b) The chemist who performed the experiment was concerned about how long to heat the hydrated crystal. The compound is known to be barium hydroxide octahydrate. In the experiment above, is it more likely that the hydrate was heated slightly too long (or perhaps at too high a heat) or not long enough? Explain your choice.
