We’re being asked to calculate the mass of PCl3 that will be formed in the reaction.
For this problem, we need to do the following steps:
Step 1: Write and balance a chemical equation for the given reaction.
Step 2: Determine the limiting reactant and calculate the mass of PCl3 formed.
Step 1: From the problem, the given chemical reaction is:
P + Cl2 → PCl3 + PCl5
This equation is not yet balanced. To balance it, we have to make sure that the number of elements on both sides is equal.
A mixture of 21.2 g of P and 79.2 g of Cl2 reacts completely to form PCl3 and PCl5 as the only products.
Find the mass of PCl3 that forms.
