Explain in detail why there is only one peak in the ferrocene 1H NMR and how it relates to the ""sandwich"" structure of the compound. (Note it is NOT enough to say there is only one type of proton. You must explain why).

Calcium carbonate decomposes at high temperatures to give calcium oxide and carbon dioxide as shown below. caco3(s) cao(s) + co2(g) the kp for this reaction is 1.16 at 800°c. a 5.00 l vessel containing 10.0 g of caco3(s) was evacuated to remove the air, sealed, and then heated to 800°c. ignoring the volume occupied by the solid, what will be the mass of the solid in the vessel once equilibrium is reached?
