Which of the following chemical equations illustrates a typical decomposition reaction?
a. A + B → AB
b. AB + CD → AD + CB
c. 2A₂+ B₂ → 2A₂B
d. AB → A + B

검증된 단계별 안내

Understand what a decomposition reaction is: it is a type of chemical reaction where a single compound breaks down into two or more simpler substances.

Analyze each equation to see if it shows one compound breaking down into simpler parts.

For option a: A + B → AB, this shows two substances combining to form one compound, which is a synthesis reaction, not decomposition.

For option b: AB + CD → AD + CB, this shows two compounds exchanging parts, which is a double replacement reaction, not decomposition.

For option d: AB → A + B, this shows one compound breaking down into two simpler substances, which fits the definition of a decomposition reaction.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Decomposition Reaction

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler substances. It is generally represented as AB → A + B, indicating the breakdown of a compound into its components.

Chemical Equation Types

Chemical equations represent different reaction types such as synthesis (combination), decomposition, single replacement, and double replacement. Recognizing the pattern of reactants and products helps identify the reaction type.

Reaction Notation and Symbols

Chemical equations use symbols and formulas to represent substances and their quantities. Understanding how to read these notations, including coefficients and reactants/products, is essential to interpret the reaction correctly.
