I chose to focus on a chemical change because it involves a transformation where the starting substances undergo a reaction to form new products with distinct properties, such as changes in color, temperature, or gas release, which are clear indicators of the process. The initial reactants may look and behave differently than the final products, highlighting the observable differences in their appearance and composition. This change emphasizes the fundamental shifts that occur at a molecular level, showcasing the dynamic nature of chemical reactions.
In 2-3 sentences, in your own words, describe why you chose that type of change in the previous question. Key points you may include in your response:
The definition of physical/chemical change
The start/end products in a physical/chemical change
The start/end appearance in a physical/chemical change
The particular visible evidence observed to indicate a physical/chemical change.
