Judge the following statements as true or false. If you believe a statement to be false, provide a corrected version. (c) Compounds can be decomposed into two or more other substances; elements cannot.

Verified step by step guidance

Understand the definition of a compound: A compound is a substance formed when two or more chemical elements are chemically bonded together.

Understand the definition of an element: An element is a pure substance that cannot be broken down into simpler substances by chemical means.

Evaluate the statement: Compounds can indeed be decomposed into two or more other substances through chemical reactions, such as decomposition reactions.

Evaluate the statement: Elements cannot be decomposed into simpler substances by chemical means, which is true.

Conclude that the statement is true as it correctly describes the nature of compounds and elements.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Compounds vs. Elements

Compounds are substances formed from two or more elements that are chemically bonded together, while elements are pure substances that cannot be broken down into simpler substances by chemical means. For example, water (H2O) is a compound made of hydrogen and oxygen, whereas hydrogen (H) and oxygen (O) are elements.

Decomposition Reactions

Decomposition reactions involve breaking down a compound into its constituent elements or simpler compounds. This process can occur through various means, such as heating or electrolysis. For instance, when water is electrolyzed, it decomposes into hydrogen and oxygen gases.

Chemical Stability of Elements

Elements are considered the most basic form of matter and cannot be decomposed into simpler substances through chemical reactions. Each element is defined by its number of protons, and while they can combine to form compounds, they retain their identity and cannot be broken down further chemically.
