In the laboratory, concentrated hydrogen chloric acid reacted with aluminum. Hydrogen gas was collected over water at 25 degrees Celsius and had a volume of 355 cm33 at a total pressure of 750 mm Hg. The vapor pressure of water at 25 degrees Celsius is 24 mm Hg. Find the partial pressure of hydrogen gas. ​

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.
