Answer: 2 PCl3 + 2 Cl2 > 2 PCl5
Explanation: The factors will be 2 moles of PCl3 reacted to 2 moles of chlorine gas Cl2 and the reaction will produce 2 moles of Phosphorous pentachloride PCl5.
For the reactants 2PCl3 +2 Cl2 there will be 2P, Cl (2x3) +
(2x2) so chlorine will have 10. In the product side 2PCl5. 2 P and Cl will have (5x2)=10.
The chemical reaction will have a balance chemical equation.
