A solution of ammonium sulphate fertilizer was to be applied to the soil before planting some seeds a given volume of water was put in
a large container and 3.68kg of fertilizer was dissolved in it. on analysis, 0.28dm3 of 0.35moldm3 barium chloride was
required to precipitate all the sulphate in 0.20dm3 of solution what was the volume of solution in the container?

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.
