What is the difference between a chemical equation and a word equation?

• A. A chemical equation uses symbols and formulas, while a word equation uses words to describe the reaction.
• B. They are the same.
• C. A word equation uses symbols.
• D. A chemical equation is about energy only.

Answer: (A)

The difference lies in how the reaction is shown. A chemical equation uses symbols and formulas to represent the actual substances involved and often includes coefficients to show how much of each substance reacts and is formed, with possible states and energy changes. A word equation describes the same reaction using names written in words, not symbols, so it conveys what happens but not the precise chemical substances or the exact amounts in formula form. This is why the description that a chemical equation uses symbols and formulas while a word equation uses words is the best explanation.
