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,
Siddharth
