Silver nanoparticles are included in the material that sports socks are made from. Silver nanoparticles can kill bacteria.
Silver nanoparticles can have a diameter between 1.120x10-9 m
and 1.008x10-8 m.
A silver atom has a diameter of 2.8x10-10 m.
Give the maximum and minimum number of silver atoms in the
thickness of one nanoparticle.

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.
