Amixture of oxygen and hydrogen is analyzed by passing it over hot copper oxide and through a drying tube. hydrogen reduces the cuo to metallic cu. oxygen then reoxidizes the copper back to cuo. we know that 100 cm3 of the mixture measured at 25o c and 750 mm yields 84.5 cm3 of dry oxygen measured at at 25o c and 750mm after passage over cuo and the drying agent. what is the original composition of the mixture? (hint: first write balanced chemical equation for the reactions.)
