Question

. P4 (s) + 10 Cl2 (g)  4 PCl5 (g)
a) This equation reads, 1 molecule of P4 react with 10 molecules of Cl2 to produce 4 molecules of PCl5. How many molecules of Cl2 do you need to react with 5 molecules of P4? Clearly show your work.

Answer 1

it's it takes 1 mole of P4 to react with 10 moles of Cl2
then 5 moles of P4 = 10x5 = 50 moles of Cl2

Answer 2

Thank you! :)
