a steel tank of oxygen has a volume of 2.00 l. if all of the oxygen is transferred to a new tank with a volume of 5.50 l, the pressure is measured to be 6.75 atm. what is the original pressure of the oxygen gas? assume constant temperature

An experimental procedure requires a 10 ml of acid to be dissolved

What is the molecular weight of copper

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.
