Students heat calcium carbonate in a crucible causing it to decompose into calcium oxide and carbon dioxide. CaCO3 Cao + 1020 (5) The stoichiometry predicts that 10.0 grams of Caco, will turn into 5.6 grams of Cao. The actual experiment, however, resulted in 5.0 grams of compound in the crucible after the heating. Suggest a source of error in the actual experiment and explain how that error would have made the mass of CaO appear to be too low. (10 pts)​

Steam reforming of methane ( ch4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
