Answer
The product of the reaction between calcium and oxygen is calcium oxide (CaO).
Explanation
1. Calcium (Ca) is a metal that reacts with oxygen (O₂) in the air to form calcium oxide.2. The reaction is a synthesis reaction where two or more reactants combine to form a single product.3. The balanced chemical equation for the reaction is:
4. In this reaction, two atoms of calcium react with one molecule of oxygen (which consists of two oxygen atoms) to produce two units of calcium oxide.5. This type of reaction is also known as an oxidation reaction, where the metal (calcium) is oxidized by the oxygen.Therefore, when calcium reacts with oxygen, the product formed is **calcium oxide (CaO)**.
