Suppose a bag full of ice (450 g) at 0.0°C sits on the counter and begins to melt to liquid water. 1.How much energy must be absorbed by the ice if 3/4 of it melted?


2.Would this problem involve a heating or cooling curve?

oHeating
oCooling

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?
