Question

Explain by writing a word equation - Respiration is a chemical change.

Answer 1

Cellular respiration is the chemical reaction in which glucose and oxygen are turned into water, carbon dioxide, and energy (ATP). ... When usingchemical formulas, it is important to make sure the atoms on the left and right are balanced as nothing is created or destroyed in the process....
The chemical equation is C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water).....

Answer 2

Dear Student,

A reaction that changes chemical composition of components involved is called a chemical reaction.

◆ Respiration is a chemical change -

• During cellular respiration, glucose reacts with oxygen to form carbon dioxide and water.
• Word equation is -

Glucose + Oxygen --> Carbon dioxide + Water

• Here, reactants (glucose and oxygen) react to form products (carbon dioxide and water).
• As chemical composition of the substances change here, this is called a chemical change.

Thank dear. Hope this helps you...
