The reaction of phosphorus pentachloride (PCl 5) with phosphorus pentoxide (P 4 O 10). 6 PCl 5 + P 4 O 10 → 10 POCl 3. The reaction can be simplified by chlorinating a mixture of PCl 3 and P 4 O 10, generating the PCl 5 in situ. The reaction of phosphorus pentachloride with boric acid or oxalic acid: [12] 3 PCl 5 + 2 B(OH) 3 → 3 POCl 3 + B ...

Whether you're an athlete looking to make gains in the gym or someone looking to lose weight, tracking your body composition can be an asset, say experts.
Phosphoric chloride difluoride can be made by the reaction of liquid phosphorus pentachloride with phosphorodifluoridic acid HPO 2 F 2 or diphosphoridic tetrafluoride P 2 O 3 F 4. This reaction takes place at room temperature up to 60 °C. The POF 2 Cl bubbles off as a gas, and can be condensed by cooling with dry ice-acetone mixture. [3]
