Problem
Identify reactants and products in a chemical equation.
Answer
a) Reactants: Carbon dioxide, Water b) Products: Glucose, Oxygen, Light energy
Step-by-step solution
- Understand Chemical Equations: A chemical equation represents a chemical reaction. It shows the substances that react (reactants) and the substances that are formed (products). The arrow in the equation indicates the direction of the reaction, from reactants to products.
- Identify Reactants: In the given word equation, 'carbon dioxide + water $\rightarrow$ light energy glucose + oxygen', the reactants are the substances on the left side of the arrow. These are the substances that are combined or react together.
- Identify Products: The products are the substances formed as a result of the reaction. In this equation, they are on the right side of the arrow. The phrase 'light energy' above the arrow indicates a condition or catalyst for the reaction, and it is also considered part of the products in this context, as it is released or utilized in the process leading to the formation of glucose and oxygen.
- Answer Part a) - Select Reactants: Based on step 2, the reactants are carbon dioxide and water.
- Answer Part b) - Select Products: Based on step 3, the products are glucose, oxygen, and light energy.
