Of melting ice or corroding silver or a burning match or rotting vegetation which is not an example of a chemical change?

Answer 1

Of melting ice, corroding silver, a burning match and rotting vegetation, melting ice is not a chemical change. The melting of ice, a change of state, represents a physical change. All the other examples represent chemical changes, as chemical reactions are occurring.

As silver corrodes, the silver chemically combines with other elements to become tarnished. When a match burns, the phosphorous and wood burn can new chemical compounds are created. When vegetable material rots, molecules of biochemical material break down and form new compounds.

Answer 2

Melting ice is not an example of a chemical change, as it involves a phase change from solid to liquid without altering the chemical composition of the ice.
