A 12.39 g sample of phosphorus reacts with 40.75 g of chlorine to form only phosphorus trichloride (PCl3). If it is the only product, what mass (g) of PCl3 is formed? A possibly useful molar mass is P = 30.974 g/mol; PCl3 = 137.324 g/mol; Cl = 35.45 g/mol.

The answer is "52.18 g"

Explanation:

Phosphorus mass = 12.39  

molar mass of

Phosphorus moles =  

mass = 40.75 g

 molar mass

 moles  =  

The balanced equation is:

In the step1:

Consider reactor limiting the reaction current is less than necessary quantity as per the balanced equation is considered reactor limiting  

The equilibrium equation:

Moles of required = 0.6 moles

But only , moles are less than the amount needed Thus, is reactant restricted  

In the step2:

Find Theoretical performance the amount formed when the reactant is fully restricted

From equilibrium  

shaped mass  =

shaped mass =

Mass shaped by  =

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
