Answer

Answer:

All of the above statements can be valid reasons depending on the context of a chemical reaction involving copper. So, if we assume this is a multiple - choice where we can check all applicable reasons:

  • Copper oxide is the only product, and it contains copper and oxygen.
  • One of the reactants is copper, so the other reactant must be oxygen.
  • The copper metal must have combined with something in the air.

Explanation:

Step1: Analyze the product

If copper oxide is the only product and it has copper and oxygen, it implies a reaction with an oxygen - containing species.

Step2: Consider reactants

Given copper as a reactant, oxygen is a likely other reactant to form copper oxide.

Step3: Think about the source of oxygen

Since the reaction occurs in air, it is reasonable to assume copper combines with something in the air, and oxygen is a major component of air that can react with copper.
