Question

this question makes me goes nuts...so the question is
oxide M is green
Metal M is grey
Oxide M can be reduced to metal M when heated with hydrogen
c)The empirical formula of oxide M cannot be determined by heating oxide M with magnesium. Explain why?

The following question makes me nuts: M is a grey metal; an oxide of M is green. When the oxide of M is heated in the presence of hydrogen, it is reduced to metallic form. Can you explain why the empirical formula of the oxide of M cannot be determined by heating the oxide of M with hydrogen?

A couple of notes. I think there's an error in your transcription -- the heating would be done with hydrogen, not magnesium. In spite of the presence of the word "why," "Explain why" is not a question; it's a command. The first appearance of "oxide" is preceded by the indeterminate article because there may be several green oxides of M. (I'm not sure, but if I'm right about the transcription error, then I think this is the key to answering the question in chemistry class.) Subsequent appearances of "oxide" are preceded by the determinate article, because one has been selected.
