You pull a sled with a package on t across a snow-covered fiat lawn. If you apply a force of 46.8N to the sled, I accelerates at 0.75 m/s2 What is the
combined mass of the package and the sied? (Assume there is no friction

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?
