Which term is the chemical property of being able to burn?

• A. Hydrogen ion (H+)
• B. Salt
• C. Combustibility
• D. Acid

Answer: (C)

The ability to burn is a chemical property because it describes how a substance reacts with oxygen in a combustion process, forming new substances and releasing energy. This change involves rewriting the material’s composition, not just a change in appearance or state, so it’s a chemical property. Combustibility (often called flammability) is the term that captures this idea. Some materials ignite easily, while others require more heat, but in all cases burning involves a chemical reaction with oxygen. Elements like a hydrogen ion, or substances described as salt or acid, don’t inherently define the burning capability, so they don’t fit this description.
