Question

Complete the following chemical reaction equation:
${{P}_{4}}+S{{O}_{2}}C{{l}_{2}}\to$

Answer 1

Phosphorus is considered as the chemical element which has the oxidation number equal to 15. All the types of phosphorus are stable at the room temperature. The different types of phosphorus are yellow phosphorus, red phosphorus, purple phosphorus, black phosphorus and white phosphorus. The red phosphorus and purple phosphorus are considered as the non crystalline solid whereas the black phosphorus is considered a sthe allotrope which is equivalent to graphite in the lead pencil.

Complete step-by-step answer: There are different types of reaction such as displacement reaction, double displacement reaction, combination reaction, redox reaction, and disproportional reaction.
In the question the given equation will form the products according to a single displacement reaction. The single displacement reaction is also known as a single replacement reaction which is a type of oxidation reduction reaction or the redox reaction. In this reaction one element is replaced with the other element in the reaction.
So in the given reaction one element will be oxidised whereas the other will be reduced. Here in the reaction the oxidation number of phosphorus is zero (0) and of sulphur is +6. The products which will be formed on reacting phosphorus with sulphuryl chloride are phosphorus pentachloride and sulphur dioxide. The reaction is as follows:
${{P}_{4}}+S{{O}_{2}}C{{l}_{2}}\to PC{{l}_{5}}+S{{O}_{2}}$
The reaction is not balanced so we will multiply the sulphuryl chloride by 10 and phosphorus pentachloride by 4 to give the balanced reaction. the reaction is:
${{P}_{4}}+10S{{O}_{2}}C{{l}_{2}}\to 4PC{{l}_{5}}+S{{O}_{2}}$
In phosphorus pentachloride the oxidation number of phosphorus is +5 and sulphur in sulphur dioxide is +4. So the oxidation number of phosphorus increases from 0 to 5 so it has undergone oxidation and sulphur has been reduced as its oxidation number decreases from +6 to +4.
So the products are phosphorus pentachloride and sulphur dioxide.

Note: In the combination reaction we see two or more compounds get combined to form only one product. In the decomposition reaction the complex molecule gatebreak down to form the simpler molecules. In the displacement reaction one element tends to take the place of the other element in the compound. In the neutralization reaction the acid and base react to form the water and salt.
