Container A has a volume of 1.23cm^3 and contains a gas under 4.56atm of pressure. Container B has a volume of 0.93cm^3 and contains a gas under 3.23atm of pressure. Container C has a volume of 1.42cm^3 and contains a gas under 2.24atm of pressure. If all of these gases are put into container D (volume of 1.51cm^3), what is the pressure in container D?

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?
