• weaker

What are the products of this reaction?

carbon + copper(II) oxide -----> ???

• copper(II) + carbon dioxide

• copper + carbon dioxide

• copper(II) carbon + oxygen

• no reaction

Answer explanation

Carbon is higher than copper in the Reactivity Series. Thus, carbon can displace copper from copper(II) oxide.
