One day in lab, while adding a gnarled root to a dark liquid bubbling in an iron cauldron, your friend Raina (an expert chemist) says this: "Many metals can be produced from their oxide ores by reaction at high temperatures with carbon monoxide. Carbon dioxide is a byproduct." Using Raina's statement, and what you already know about chemistry, predict the products of the following reaction. Be sure your chemical equation is balanced! CoO(s) + CO(g) ->
