I chose a chemical change because it involves a transformation that alters the composition of a substance, resulting in different start and end products. For instance, during a chemical change, the original substances may appear distinct, with new characteristics—like color change or gas production—indicating that a new substance has formed. This evidence, such as temperature shifts or the release of light, highlights the significant differences between the reactants and the products.
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 evidence observed to indicate a physical/chemical change.
