A jet pack is a type of rocket system that
can allow a human to "fly" for short
distances. What can you infer about how jet
packs work?
The thrust created by a jet pack must be greater than the
force of gravity acting on the user and the pack.
The user must weigh less than the jet pack to lift off the
ground.
The weight of the fuel in the jet pack must be greater than
the weight of the user in order to achieve liftoff.
The force of gravity on the user must decrease as he is
lifted off the ground.

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.
