Chemical engineering. the product gas from a coal gasification plant consists of 60.0 mole % co and the balance h2; it leaves the plant at 150° c and 2000 psia. the gas expands through a turbine, and the outlet gas from the turbine is fed to a boiler furnace at 100° c and 1atm at a rate of 15,000 ft^3/min. estimate the inlet flow rate to the turbine in ft^3/min using kay's rule. what percentage error would result from the use of the ideal gas equation of state at the turbine inlet?

Which statement best describes the function of enzymes?

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
