Phosphorus trichloride, PCl3, decomposes to form elemental phosphorus and chlorine. The equation is: 4PCl3 → P4 + 6Cl2. Balance the equation and determine the mass in grams of chlorine that would be formed if 25 grams of PCl3 (molecular mass = 137.32 g/mol) decompose.

Respuesta :

The equation is balanced as written. 
25 g / 137.32 g/mol x (6/4) x 70.9064 g/mol = 19 g of Cl2
