Answer 1

The most accurate 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.

Dissolving typically is considered a physical change because the substances retain their individual molecular structures and can be recovered (e.g., by evaporation), but certain cases, such as with some ionic compounds, may involve changes at the molecular level, making classification ambiguous.
