Why is frying an egg an example of a chemical change?
a- atoms are lost during the reaction as bonds are broken.
b- atoms are gained during the reaction as new bonds form.
c- the products have different properties than the reactants.
d- the properties of the reactants are seen in the products.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
