When 100.0 mL of 2.00 M Ce(NO3)3 is added to 100.0 mL of 3.00 M KIO3, a precipitate of Ce(IO3) 3 (s) forms. Calculate the equilibrium concentrations of Ce3+ and IO3- in this solution. (Ksp for Ce(IO3) 3 = 3.2x10^-10)?

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.
