Answer 1

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 highlights that during dissolution, the behavior and properties of substances can vary significantly. In some cases, the solute retains its molecular identity, indicating a physical change, while in other instances, the interactions may alter the molecular structure, suggesting a chemical change.
