For every 6°C drop in temperature, the air pressure in a car's tires goes
down by about 1 psi (14.7 psi = 1.00 atm). Make a
graph illustrating the change in tire pressure from
20°C to -20°C (assume 30.0 psi at 20°C).

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?
