Which of the following describes the product of a chemical reaction

I believe the correct answer would be the substances that are formed. Why?  Because during a chemical change, the substances (scientifically called reactants) which are changed into other substances are called products.  

Hope I could help! :)

Atoms in substances react with each other

Explanation:

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.

im doing test rn im going with 2 but ill give answer if itss wrong,   : )
