Consider the balanced equation below.

Upper P Upper C l Subscript 3 Baseline + Upper C l Subscript 2 Baseline right arrow Upper P Upper C l Subscript 5.
What is the mole ratio of PCl3 to PCl5?

Respuesta :

Answer: The mole ratio of [tex]PCl_3[/tex] to [tex]PCl_5[/tex] is 1: 1

Explanation:

According to the balanced chemical equation ,the number of atoms of each element has to be same on reactant and product side. The stoichiometric coefficients of the species represent their number of moles.

[tex]PCl_3+Cl_2\rightarrow PCl_5[/tex]

Thus in the reactants, there is 1 mole of [tex]PCl_3[/tex] and 1 mole of [tex]Cl_2[/tex] molecule. And thus there is 1 mole of [tex]PCl_5[/tex] in the product as well.

Thus the mole ratio of [tex]PCl_3[/tex] to [tex]PCl_5[/tex] is 1: 1
