1. A 0.2 kg hockey puck undergoes a slap shot moving 14 m/s to the left side of the goal. The goalie moves to stop the puck at 3 m/s to the left also. The goalie saves and blocks the shot and the puck collides into a
1.5 kg glove of the goalie and the glove with the puck both continue moving to the left. Calculate the
velocity of the glove and puck moving immediately after the collision.

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.
