Which term describes a pure substance that can be broken down by chemical means into two or more simpler substances?

• A. Organic Compound
• B. Compound
• C. Buffer
• D. Solution

Answer: (B)

The term describes a pure substance composed of two or more elements that are chemically bonded and can be broken down by chemical means into simpler substances. This is exactly what a compound is: a definite, fixed composition formed from elements, which can be decomposed into those elements or into other simpler substances through chemical reactions. For example, water is a compound that can be split into hydrogen and oxygen via electrolysis. An organic compound is a type of compound, but not all compounds are organic. A buffer is a system that resists changes in pH and is typically a mixture, not a pure substance. A solution is a homogeneous mixture, not a pure substance.
