Predict the sign of `DeltaS` for the reaction :
`CaCO_(3)(s) overset(Delta) to CaO(s) + CO_(2)(g)`

Explanation

To predict the sign of ΔS (change in entropy) for the reaction:

\[ \text{CaCO}_3(s) \overset{\Delta}{\rightarrow} \text{CaO}(s) + \text{CO}_2(g) \]

we will analyze the states of the reactants and products involved in the reaction.
