Without calculation, predict (giving you reasoning) whether the entropy change for the following reaction will be significantly positive, significantly negative or approximately zero: MgO(s) + CO2 (g) --> MgCO3 (s)

Significantly negative. A gas is turning into a solid thus there is less of a tendency towards randomness.
