Fe + cucl2 mc009-1.jpg fecl2 + cu which pair of substances are the products?

Answer : and pair of substances are the products.

Explanation :

The given balanced chemical reaction is,

Balanced chemical reaction is the reaction in which the number of atoms of an individual elements present on reactant side must be equal to the product side.

The species present on the left side of the right arrow is the reactant and the species present on the right side of the right arrow is the product.

In the given balanced reaction,

and are reactants.

and are products.

Hence, and pair of substances are 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.
