Question

PH3<--P-->P2O3-->P2O5-->H3PO4-->(NH4)3 PO4

Answer 1

P4 + 6H2 = 4PH3

P4 + 3O2 = 2P2O3

P2O5 + 3H2O = 2H3PO4

H3PO4 + 2(NH3•H2O) = (NH4)2HPO4 + 2H2O

Answer 2

The chemical equation you provided shows the reaction pathway from PH3 to (NH4)3PO4, involving various phosphorus compounds. Let's break down the steps of the reaction:

Step 1: PH3 (Phosphine) reacts with P2O3 (Phosphorus trioxide). PH3 + P2O3 → P2O5 + H2

Step 2: P2O3 (Phosphorus trioxide) reacts with oxygen to form P2O5 (Phosphorus pentoxide). P2O3 + O2 → P2O5

Step 3: P2O5 (Phosphorus pentoxide) reacts with water to form H3PO4 (Phosphoric acid). P2O5 + H2O → 2H3PO4

Step 4: H3PO4 (Phosphoric acid) reacts with (NH4)2O (Ammonium oxide) to form (NH4)3PO4 (Ammonium phosphate). H3PO4 + 3(NH4)2O → (NH4)3PO4 + 3H2O

Overall, the reaction pathway can be summarized as: PH3 + P2O3 → P2O5 + H2 P2O5 + H2O → 2H3PO4 H3PO4 + 3(NH4)2O → (NH4)3PO4 + 3H2O

Please note that these reactions are generalized and might require specific reaction conditions such as temperature, pressure, and catalysts to proceed efficiently.
