Teddio, you are correct in that the question is incomplete and vague. Furthermore, I acknowledge that at face-value it might not be correct to assume that the question was about blast-furnace reduction. It was a mere off the cuff remark about a typical practical application of the reaction.
Nevertheless, you have to concede that each of the compounds and gases mentioned are formed in the correct sequence during blast-furnace production, so as far as the reaction is concerned, yes, blast furnace reduction might be said to be a process during which these sequence of reactions occur. Offhand, I know of no other and I'm pleased that you acknowledge that the reaction is probably about the blast furnace reaction in your last post. I merely used the reaction to outline a typical process during which such a sequence occurred.
As you are aware, oxygen is needed for the reaction stages to occur. the fact that this oxygen is sourced from air is incidental and it would work equally well with pure oxygen when cost was left aside.
I added my contribution as Mrs Y omitted to mention that carbon dioxide is the first gas produced rather than carbon monoxide.
The thing that baffled me for a few moments was the randomness of the two questions. I then realised that they might be taken from a class workbook that merely required short answers. I've never been a fan of these books and this is just another example about how kids nowadays often fail to appreciate the finer points of the sciences.
