Problem
Identify reactants and products in a chemical word equation.
Answer
a) Reactants b) Products
Step-by-step solution
- Understand Chemical Equations: A chemical equation represents a chemical reaction. It shows the substances that react and the substances that are formed. The general format is: Reactants $\rightarrow$ Products.
- Identify Reactants: In the given word equation, 'glucose + oxygen $\rightarrow$ carbon dioxide + water', the substances on the left side of the arrow are the reactants. These are the substances that are consumed or change during the reaction.
- Answer Part a): Therefore, glucose and oxygen are the reactants.
- Identify Products: The substances on the right side of the arrow are the products. These are the new substances formed as a result of the reaction.
- Answer Part b): Therefore, carbon dioxide and water are the products.
