You want to make a retangular box that weighs 2.0 pounds and floats on water. The width and height of the box are each 5.0 cm long. Choose the minimum length of the box that will keep it afloat on the water. Assume the density of the water is 1.0g/cm^3. Show all work and explain in words why you chose your answer. A) 180 cm B) 360 cm C) 9.7 cm D) 7.3 cm E) 38 cm

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.
