GPT-4o mini · Answer

The best response to why it is difficult to classify dissolving as simply a physical or a chemical change is:

Some substances keep the same molecular structure when they break down, and others do not.

This is key because in many cases, the substances that dissolve retain their molecular integrity, indicating a physical change. However, in other cases, the process can involve chemical interaction, leading to the formation of new substances. This complexity makes a clear classification challenging.
