A3.0 l container holds a sample of hydrogen gas at 300 k and 100 kpa. if the pressure increases to 300 kpa and the volume remains constant, what will the temperature be? 600 k 900 k 300 k 100 k

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?
