what type of reaction is this?

Question

An important industrial process is refining iron ore in a blast furnace. Carbon trades places with Iron metal from Iron (III) oxide to produce pure Iron and carbon dioxide gas.

Answer 1

3C + 2Fe2O3 --> 4Fe + 3CO2

 

This is an oxidation/reduction reaction, where C is oxidized (loses electrons) and iron is reduced (gains electrons).  C goes from oxidation number zero on the left to oxidation number 4+ on the right.  Iron goes from oxidation number 3+ on the left to zero on the right.
