At 1023 k and 1 atm, a 3.00 gram sample of sno2(s) (gram-formula mass = 151 g/mol) reacts with hydrogen gas to produce tin and water, as shown in the balanced equation below: sno2 (s) + 2 h2 (g) > 2 h2o (g) + sn (l) determine the number of moles of sn(l) produced when 4.0 moles of h2(g) is completely consumed.

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?
