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?

What are the coefficients that will balance the skeleton equation below? n2 + h2 → nh3

C8h18(g) + o2(g) →co2(g)+h2o(g) how many grams of oxygen are required to react with 17.0 grams of octane (c8h18) in the combustion of octane in gasoline?
