Which term describes a substance that is normally stable?

• A. Potentially hazardous
• B. Inert ingredient
• C. Explosive potential
• D. Stable compound

Answer: (D)

The term that describes a substance that is normally stable is "stable compound." A stable compound is one that maintains its structure and properties under normal conditions and does not readily undergo chemical changes. This stability is important in various contexts, including storage, handling, and usage, as it implies that the substance will not react dangerously under typical conditions.

In contrast, a potentially hazardous substance refers to materials that can pose risks under certain conditions, such as becoming reactive or toxic. Inert ingredients are substances that do not react chemically and are often used to dilute or carry other materials, but they are not specifically described as stable in all conditions. Explosive potential refers to a substance's ability to release energy rapidly upon reacting, indicating instability rather than stability. Therefore, "stable compound" accurately captures the definition of a substance that is reliable and not prone to unintended reactions.
