Asample of ideal gas is in a sealed container. the pressure of the gas is 485 torr , and the temperature is 40 ∘c . if the temperature changes to 74 ∘c with no change in volume or amount of gas, what is the new pressure, p2, of the gas inside the container?

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?
