Explanation:
In this reaction the products have less potential energy than the reactants.
A scheme of a chemical reaction. The reactants are two molecules, one of which consists of A and B, and the other consists of C and D.
The products are two molecules, one of which consists of A and C, and the other consists of B and D.
The energy of molecules AB and CD is higher than the energy of molecules AC and BD.
In this reaction heat has been released to the environmen.

The products are two molecules, one of which consists of A and C, and the other consists of B and D.
The energy of molecules AB and CD is higher than the energy of molecules AC and BD. CD is a product entropy has decreased the products have less potential energy than the reactants AC is a reactant the products have been rearranged to form reactants.
Answer:
One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant. The concept of the mole can be used to convert between mass and number of particles
