Reggie and Charlotte are baking oatmeal cookies. They dip the baked cookies in melted chocolate. The chocolate cools to form a hardened coating. Reggie argues the entire chocolate-covered cookie has undergone a chemical change. Charlotte disagrees, saying only the original oatmeal cookie has undergone a chemical change, not the chocolate coating.
Who is correct?
A>Reggie, because baking and melting cause bonds to be broken, leading to a chemical change.
B>Reggie, because objects that are heated always undergo chemical changes.
C Charlotte, because melting objects only sometimes cause a chemical change.
D Charlotte, because baking causes a chemical change, but melting objects is a non-chemical change.
