Question

Which of the following demonstrates a chemical change?(1 point) Responses iron (Fe) reacting to water((H2O) ) and oxygen(O) to form iron oxide(Fe2O3 ) iron (Fe) reacting to water(open paren cap h sub 2 cap o close paren) and oxygen(O) to form iron oxide(cap f e sub 2 cap o sub 3) dry ice vaporizing dry ice vaporizing sugar and water mixing to create sugar water sugar and water mixing to create sugar water steam condensing on a mirror steam condensing on a mirror

Answer 1

The option that demonstrates a chemical change is:

**Iron (Fe) reacting to water (H₂O) and oxygen (O) to form iron oxide (Fe₂O₃).**

This reaction involves the transformation of iron and other substances into a new compound (iron oxide), which is a characteristic of a chemical change. The other options involve physical changes rather than chemical changes.
