Hi,

I was going through some old quizzes for practice and I found an error that might need to be fixed. Here, it says P2S5 is Diphosphorus pentsulphide, but shouldn't it be Diphosphorus pentasulphide? Also, just as a general question, since I live in America, is it appropriate to call it pentasulfide instead of pentasulphide, or is sulphide the generally acknowledged term?

Note: I have flagged the question in the quiz titled "Formulas and Nomenclature of Covalent molecules"

Thanks,

You are right in USA it is sulfur and in Europe and Asia it is Sulphur.
So correct name is sulfide.
I will correct it. Thanks for reminding.
