All of the following are evidence of chemical changes except:

a) talking antacid for heartburn

b) cooking steak

c) salt dissolving in water

d) grass growing

d) grass growing

Explanation:

i believe because everything else has something happening where it wasn't the same as before but grass is still the same color texture but its just longer

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.
