A 10-mm cube of copper metal is placed in 250 mL of 12 M nitric acid al 25C and the reaction below occurs: Cu(s) + 4H*(aq) + 2NO, (aq)-> Cu2+(aq) + 2NO2(g) + 2H2O(1) At a particular instant in time, nitrogen dioxide is being produced at the rate of 3.5 x 10^-4 M/min. At this same instant, what is the rate at which hydrogen ions are being consumed in M/min? Da not write a unit in answer. Report your answer with five places past the decimal point.
