e) Endothermic

2. a) The reaction is endothermic. Energy must be absorbed to break the bonds in copper carbonate, and since decomposition requires continuous heating, it indicates that energy is being taken in from the surroundings.

f) [Diagram description: Draw two H₂ molecules (each with one blue bond between two H atoms) and one O₂ molecule (with one blue bond between two O atoms). Show these breaking apart into individual H and O atoms. Then draw two H₂O molecules, each with two red bonds (one between each H and the O atom).]
