Which of the following is a chemical property of carbon tetrachloride (CCl_4)?

• A. CCl_4 is nonflammable under normal conditions.
• B. CCl_4 is a good conductor of electricity.
• C. CCl_4 has a sweet odor.
• D. CCl_4 is highly reactive with water at room temperature.

Answer: (A)

Verified step by step guidance

1. Understand the difference between physical and chemical properties. Physical properties can be observed without changing the substance's identity, while chemical properties describe how a substance interacts or changes into a new substance.
2. Analyze each statement to determine if it describes a physical or chemical property:
3. - "CCl_4 is nonflammable under normal conditions" describes how CCl_4 behaves in a chemical reaction (combustion), so it relates to its chemical reactivity.
4. - "CCl_4 is a good conductor of electricity" refers to an electrical property, which is physical because it does not involve a chemical change.
5. - "CCl_4 has a sweet odor" is a sensory physical property, as it describes how the substance smells without changing its composition.
6. - "CCl_4 is highly reactive with water at room temperature" describes a chemical reaction with water, indicating a chemical property.
7. Identify which statements describe chemical properties by focusing on those that involve reactivity or chemical change.
