Croquet balls must have a mass of 0.50 kg. A red croquet ball, moving at 10 m/s, strikes an at-rest green croquet ball head-on. The red ball continues
moving at 1.5 m/s after it hits the green ball. What is the final speed of the
green ball?
O A. 5 m/s
B. 8.5 m/s
C. 1.5 m/s
O D. 15 m/s

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.
