Scientist have sent an unmanned space vehicle to Mars to investigate the properties of the planet. Mars’ gravitational field is 38% the strength of Earth’s gravitational field. How will the weight and mass of the vehicle change on Mars. A. The mass will increase, and the weight will increase
B. The mass will decrease, and the weight will decrease
C. The mass will remain the same, and the weight will decrease.
D. The mass will increase, and the weight all remain the same.

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.
