The mole ratio is 1:1 because when you're looking for the MOLE ratio in an equation, you have to always use the coefficients in front of the elements (just emphasizing the word mole since the previous answer was wrong) , and since there is an invisible 1 in front of both Cl2 and CaCl2, therefore the ratio is 1:1.
1 to 1.
PCl5 -----> PCl3 + Cl2
In presence of moisture, PCl3 hydrolyses to form HCl which fumes in air.The reaction is as follows: PCl3 + 3H2O -------> H3PO3 + 3HCl
Phosphorus trichloride is not dissolved in water, a reaction of hydrolysis occur.
PCl3(g) + Cl2(g) PCl5(g)
PCL3
PCl3 + H2O  H3PO3 + 3HCl
The reaction will proceed to the right. 2 PCl3 will be consumed.
PCl5 -----> PCl3 + Cl2
The reaction will proceed to the left. PCl5 will be formed. PCl3 will be consumed.
P+Cl+Cl+Cl 31+35+35+35 so the answer is 136
In presence of moisture, PCl3 hydrolyses to form HCl which fumes in air.The reaction is as follows: PCl3 + 3H2O -------> H3PO3 + 3HCl

show you the balance reaction between water and phsphorous trichloride show you the balance reaction between water and phsphorous trichloride show you the balance reaction between water and phsphorous trichloride
PCl3(g) + Cl2(g) PCl5(g)
PCL3
PCl3 is the chemical symbol for phosphorous trichloride.
PCl3 is the chemical formula for phosphorous trichloride.
