Question

For each statement, answer with YES if evidence of a chemical reaction is present. Answer NO if there is no evidence of a chemical reaction. A piece of ice melts?

1) YES
2) NO

Answer 1

A piece of ice melting represents a chemical change.

Step-by-step explanation:

The statement 'A piece of ice melts' does represent a chemical change, so the answer is YES. When ice melts, it undergoes a phase change from a solid to a liquid, which is a physical change. However, this physical change is the result of the breaking of hydrogen bonds between the water molecules in the ice, which is a chemical change. So, even though the overall composition of the substance remains the same, a chemical reaction is still occurring.
