1.45g P4 * 1mol P4 / 124g P4 Does this type calculation has a standard formula??

[@phillwithskill1364]

Is it correct to simplify this: P4 + 6Cl2 ----> 4PCl3 to this: P4 + 3Cl2 ----> 2PCl3 ?

[@willcruise9452]

You have to do the same thing to every variable. You’d have to divide P4 by 2 ad well.

[@phillwithskill1364]

Will Cruise Thank you!

[@fergushalligan1891]

No because you're leaving P without changing anything so the equation isnt balanced

[@fergushalligan1891]

plus, if you were to do that it would be 0.5P4 + 3Cl2 ---> 2PCl3
