During photosynthesis, plants use energy from sunlight to form glucose (C6H12O6) and oxygen from carbon dioxide and water. Write a balanced equation for photosynthesis.

Guida verificata passo dopo passo
1
Identify the reactants and products in the photosynthesis process: carbon dioxide (CO_2), water (H_2O), glucose (C_6H_{12}O_6), and oxygen (O_2).
Write the unbalanced chemical equation: CO_2 + H_2O \(\rightarrow\) C_6H_{12}O_6 + O_2.
Balance the carbon atoms: Ensure there are 6 carbon atoms on both sides by placing a coefficient of 6 in front of CO_2.
Balance the hydrogen atoms: Ensure there are 12 hydrogen atoms on both sides by placing a coefficient of 6 in front of H_2O.
Balance the oxygen atoms: Adjust the coefficients to ensure the number of oxygen atoms is equal on both sides of the equation.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Photosynthesis

Photosynthesis is the biochemical process by which green plants, algae, and some bacteria convert light energy into chemical energy. This process primarily occurs in the chloroplasts of plant cells, where chlorophyll captures sunlight to drive the conversion of carbon dioxide and water into glucose and oxygen.

Balanced Chemical Equation

A balanced chemical equation represents a chemical reaction with equal numbers of each type of atom on both sides of the equation. This is crucial for obeying the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Balancing ensures that the reactants and products are accurately represented.

Reactants and Products

In a chemical reaction, reactants are the starting substances that undergo change, while products are the substances formed as a result of the reaction. In photosynthesis, the reactants are carbon dioxide and water, and the products are glucose and oxygen. Understanding the roles of reactants and products is essential for writing and balancing chemical equations.
