a - 0.25 mole of c has the same number of atoms as 0.25 mole of hg.
b - 1 mole of hydrogen atoms equals 1 mole of helium atoms.
c - 1 mole of carbon atoms and 1 mole of oxygen atoms are a 1: 1 ratio.
d - 1 mole of xenon atoms is more than 1 mole of neon atoms.

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.
