Answer:
24 molecules of phosphorus trichloride can be formed
Explanation:
Based on the equation:
P4(s) + 6Cl2(g) → 4PCl3
<em>1 mole of P4 reacts with 6 moles of Cl2 to produce 4 moles of PCl3.</em>
<em />
When 10 molecules of P4 react, 60 molecules of Chlorine are needed. As there are just 36 molecules, Cl2 is limiting reactant.
If 36 molecules of chlorine are added, molecules of PCl3 produced are:
36 molecules Cl2 * (4 PCl3 / 6 Cl2) =
24 molecules of phosphorus trichloride can be formed
