Answer:
Explanation:
We would heat the zinc carbonate strongly, and at 300C, we would notice the following reaction taking place:
ZnCO3 = ZnO + CO2(g) T = 300C
Change in Free Energy: ΔG(300C) = -28.5kJ (negative, so the reaction runs)
Change in Enthalpy: ΔH(300C) = +69.0kJ (positive, so the reaction is endothermic)
The zinc carbonate decomposes at 300C, producing zinc oxide ZnO and carbon dioxide. The white crystals of zinc carbonate turn into a fine white powder, zinc oxide ZnO when the carbon dioxide is evolved.
