Concept explainers
Interpretation:
The identity of phosphorus oxide and oxoacids formed in the given reaction has to be identified, and the amount of P4 in grams which was burned in the reaction should be determined.
Concept Introduction:
Phosphorus: It is a most abundant element of group 5A according for 0.10% of the mass of the earth crust.
Phosphorus oxides: Two phosphorus oxides, phosphorus(III) oxide
Phosphorus(III) oxide: It is a white crystalline solid that smells like garlic and has poisonous vapour.
Reaction of Phosphorus(III) oxide: This oxy acid react with ice water to produce a solution of the weak acid
Phosphorus(V) oxide: It is a white flocculent powder that can be prepared by heating elemental phosphorus in oxygen, it is very stable and poor oxidizing agent.
