You need to be familiar with the three states of matter and their properties and be able to apply the particle model to unfamiliar materials and contexts. Solid
Liquid
Gas
You will also need to be able to identify the suitable method of separation for a mixture.

Please you will have 25 points

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.

i think its 100

i hope this !
