Alkyl halides, phosphoryl chloride (POCl3), and HCl are all results of the reaction between phosphorus halides and alcohol.
What functions does phosphorus serve in the body?Phosphorus is essential for the synthesis of both RNA and DNA, the genetic building blocks, as well as for the growth, maintenance, and repair of all tissues and cells. Moreover, phosphorus is necessary for the balance and utilization of other vitamins and nutrients like vit D, chlorinated, magnesium, and zinc.
What foods are phosphorus-rich?Foods that are high in protein, such as meats, chicken, fish, nuts, beans, and dairy products, naturally contain phosphorus, which is available in the form of organic phosphorus. Compared to phosphorus in plant diets, phosphorus in animal - based foods is more easily absorbed.

Calculate the standard enthalpy change for the reaction at 25 ∘ C. Standard enthalpy of formation values can be found in this list of thermodynamic properties. Mg(OH)2(s)+2HCl(g)⟶MgCl2(s)+2H2O(g)
ΔH∘rxn =
The standard enthalpy change for the reaction at the 25 °C is the -16.3 kJ.
The chemical reaction is as follows :
Mg(OH)₂(s) + 2HCl(g -----> MgCl₂(s) + 2H₂O(g)
The ΔHf Mg(OH)₂ = - 924.5 kJ/mol
The ΔHf HCl = - 92.30 kJ/mol
The ΔHf MgCl₂ = - 641.8 kJ/mol
The ΔHf H₂O = -241.8 kJ/mol
The standard enthalpy change of the rection is as :
ΔH∘rxn = ∑ ΔHf product - ∑ ΔHf reactant
= ( -641.8 + (2× -241.8 ) - ( - 924.5 + ( 2 × - 92.30 ))
ΔH∘rxn = - 16.3 kJ
The enthalpy change for the reaction is -16.3 kJ.
