Umakant biswal · Answer

@ shaik
here the equation is balanced , so, we need to calculate no of moles frst ,
h2 = 3/2 = 1.5 moles
o2 = 29/32 = 0.90 moles
then just divide the no of moles with the coefficient of balanced equation
h2 = 1.5 / 2 = 0.75
o2 = 0.90/ 1= 0.90
so, here H2 will be the limiting reagent ,
