Which term means how readily a substance combines chemically with other substances?

• A. Acid
• B. Reactivity
• C. Base
• D. Salt

Answer: (B)

Reactivity describes how readily a substance combines chemically with other substances. It’s a property that tells you how likely a substance is to participate in chemical reactions and how fast those reactions may occur. Substances with high reactivity, like alkali metals, will quickly react with water or acids, forming new compounds, while substances with low reactivity, such as noble gases, tend not to react under normal conditions. The other terms refer to specific roles or products in chemistry (acids donate protons, bases accept protons, salts are products of acid–base reactions), not to the overall tendency to react. So the description in the question matches reactivity.
