Assume that a sample of humid air contains only nitrogen gas, oxygen gas and water vapor. If the atmospheric pressure is 745 mm Hg and the partial pressure of N2 is .745 atm and of oxygen is 140 mm Hg, what is the partial
pressure of water vapor in the air?

In water, a strong acid will break down into its component parts. a. completely b. partly c. never in water, a weak base will break down into its component parts. a. completely b. partly c. never

If you burn 46.6 g of hydrogen and produce 416 g of water, how much oxygen reacted

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.
