In a 1-l beaker, 213 ml of 0.345 m ammonium chromate was mixed with 107 ml of 0.227 m chromium(iii) nitrite to produce ammonium nitrite and chromium(iii) chromate. write the balanced chemical equation for the reaction occurring here. (use the lowest possible coefficients. use the pull-down boxes to specify states such as (aq) or (s). if a box is not needed, leave it blank.)
