... In this question, P2O5 is the most bulky one, we put 1 in front of it to remind us we have done examining P2O5. Now the equation is updated to __PH3 + __O2 1 P2O5 + __H2O Since P2O5 contains 2 phosphorus atoms, so we need two phosphorus atoms at the left side, which leads us to put 2 (called coeff ...
