This was the question:
solid iron(III) oxide is heated in excess carbon monoxide.
This is the answer:
Fe2O3(s) + CO(g) => Fe(s) + CO2(g)
But I don't understanding HOW they arrived at that answer. I would think that if something is heating in excess of something, then that's a combustion reaction, and my teacher told us that the standard product for a combustion reaction is carbon dioxide and water. I know that this may be an exception, but how would I go about solving this equation to arrive at that answer? I understand the CO^2 part, just don't get why Fe is left alone like that. Wouldn't it too take an oxygen to be Fe^2O^3?
