Yоu mаy hаve heаrd that mixing hоusehоld bleach with household ammonia is dangerous, this is true! Many different reactions can occur when these are mixed, almost all of them bad. One of these is shown below, where sodium hypochlorite, NaOCl (in bleach), reacts with ammonia, NH3, to give NaCl and H2O (which are harmless), and hydrazine, N2H4, which is toxic. NaOCl + NH3 → NaCl + H2O + N2H4 What is the balanced version of this equation?
