Is it possible for the entropy of both a closed system and its surroundings to decrease during the process?

Only when heat is transferred from the system to its surroundings does a closed system suffer a decrease in entropy.

Only when heat is transferred from the system to its surroundings does a closed system suffer a decrease in entropy. Every internally reversible operation in a closed system generates entropy. Entropy remains constant in an adiabatic and internally reversible process of a closed system. Isolated systems' entropy cannot diminish.

When a system is not isolated but is in contact with its surroundings, the entropy of the open system may drop, requiring a balancing rise in the entropy of the surroundings. During a process, the entropy of an isolated system constantly increases, or in the case of a reversible process, remains constant (it never decreases).

Which describes the composition of carbohydrates?
UkoKoshka [18]

Answer: Carbohydrates (carbo- = “carbon”; hydrate = “water”) contain the elements carbon, hydrogen, and oxygen, and only those elements with a few exceptions. The ratio of carbon to hydrogen to oxygen in carbohydrate molecules is 1:2:1.

The binding energy in MeV per atom is - 63284.56 Mev.

The amount of energy needed to detach a particle from a system of particles or to disperse every particle in the system is known as the binding energy. Subatomic particles in atomic nuclei, electrons attached to atom's nuclei, and atoms and ions bonded together in crystals are three examples of where binding energy is very relevant.

If we have a nucleus with Z protons and N neutrons and mass MA, where A = Z + N then its binding energy in MeV is given by: Eb(MeV) = (Zmp + Nmn - MA) x 931.494 MeV/u

Mass of atom = 69.955264 amu

Mass of proton = 1.007825 amu

Mass of neutron = 1.008665 amu

Binding energy, Mev = (Zmp + Nmn - M) × 931.494MeV/u

                                    = ( 1.007825 + 1.008665 -  69.955264) × 931.494

                                    = - 67.938774 × 931.494

                                    = - 63284.56 Mev

Therefore, the binding energy in MeV per atom is - 63284.56 Mev.
