An empty plastic bottle is sealed in a cool room and then moved to a very hot room. what can best be stated about the air pressure inside the bottle when the bottle reaches room temperature? it is lower than the pressure on the outside of the bottle. it is higher than the pressure on the outside of the bottle. it is the same as the pressure on the outside of the bottle. it exerts twice the force per unit area as the air pressure outside the bottle.

8. what happens to matter during a chemical reaction

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.
