Method for Detection of Elements - Phosphorus
Phosphorus is detected through fusing the organic compound along with sodium peroxide while phosphorus is converted into sodium phosphate. 2P + 5Na2O2→2Na3PO4 +2Na2O. The fused mass is extracted with H2O, boiled with conc. HNO3 and after that ammonium molybdate is included. Presence of yellow ppt. or colouration because of the formation of ammonium phosphomolybdate points out the presence of phosphorus.
An adiabatic air compressor is to be powered by a direct-coupled adiabatic steam turbine that is also driving a generator. Steam enters the turbine at 12.5 MPa and 500oC at a rate

For an electron if the uncertainty in velocity is Δ v , the uncertainty in its position( Δ x ) is given by: (1) hm/ 4 Π Δ b (2) 4 Π / hm Π v
Mesomeric forms are the possible locations of electrons at a single instant, if you get what I mean. Like, an adjacent double and single bond in a molecule. The resonance form, how
