You are riding a bus. your friend is standing on the street corner as the bus goes by. how would you describe the way your friend seems to move? how would your friend describe your motion? why do the descriptions differ?

How can you use chemical equations to predict the products of the reaction you can carry out?

Use examples from the article to explain one positive and one negative effect that chemistry has had on society.

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.
