The element tin often occurs in nature as the oxide SnO₂. To produce pure tin metal from this sort of tin ore, the ore usually is heated with coal (carbon). This produces pure molten tin, with the carbon being removed from the reaction system as the gaseous by-product carbon monoxide. Choose the unbalanced chemical equation for this process.
