What is the ∆g for the following reaction under standard conditions (t = 298 k) for the formation of nh4no3(s)? 2nh3(g) + 2o2(g) nh4no3(s) + h2o(l) given: nh4no3(s): ∆hf = -365.56 kj ∆sf = 151.08 j/k. nh3(g): ∆hf = -46.11 kj ∆sf = 192.45 j/k. h2o(l): ∆hf = -285.830 kj ∆sf = 69.91 j/k. o2(g): ∆hf = 0.00 kj ∆sf = 205 j/k. 186.6 kj 6.9 kj -10.4 kj -126.3 kj -382 kj

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?
