How many moles of magnesium oxide are produced by the reaction of 3.82 g of magnesium nitride with 7.73 g of water? #Mg_3N_2 + 3H_2O -> 2NH_3 3MgO#
We assess the rxn....
Is it balanced? Don't trust my arithmetic.
This tells us UNEQUIVOCALLY that
We have molar quantities of........
Water is thus present in stoichiometric excess. Do you agree?
And thus we get stoichiometric
