The decreasing order of standard molar entropy (S°) is as follow:
NO₂(g) > NO(g) > N₂(g)
<h3>What is Entropy? </h3>
Entropy is defined as the randomness of the particle. It depends on temperature and pressure or number of particle per unit volume.
It is directly proportional to the temperature and pressure of the gas.
<h3>What is Standard Molar Entropy? </h3>
The standard molar entropy is defined as the entropy content of the one mole of pure substance at the standard state of temperature and pressure of interest.
The standard molar entropy is also defined as the total amount of entropy which 1 mole of the substance acquire, as it is brought from 0K to standard conditions of temperature and pressure.
The standard molar entropy depends on the molas mass of atom, molecules or compound.
N₂ has lower standard molar entropy. This can be explained as this molecule consist of same atom.
While, Complexity increases from NO to NO₂(g). Therefore, the standard molar entropy of NO₂(g) is greater than NO.
Thus, we concluded that the decreasing order of standard molar entropy (S°) is as follow:
NO₂(g) > NO(g) > N₂(g)

Answer:
Below!
Explanation:
A planet with oceans, continents, and plate tectonics maximizes opportunities for speciation and natural selection, whereas a similar planet without plate tectonics provides fewer such opportunities. Plate tectonics exerts environmental pressures that drive evolution without being capable of extinguishing all life.
ionic bond:
Bond formed when an atom donates its electron and other atom receives those electrons.
polar covalent:
Bond formed by equal sharing of electrons between both the atoms and there is an electronegativity difference between the two atoms.
Nonpolar covalent:
Bond formed by equal sharing of electrons between both the atoms and there is no electronegativity difference between the two atoms.
Metallic:
Formed between two metals.
So the bond between :
Phosphorus and chlorine-polar covalent bond as it is formed by equal sharing of electrons between both the atoms and there is an electronegativity difference between the two atoms.
Potassium and oxygen -ionic bond as here potassium donates its electron and oxygen receives those electrons
Fluorine and fluorine -Non polar covalent bond as formed by equal sharing of electrons between both the atoms and there is no electronegativity difference between the two atoms.
Copper and aluminum-metallic bond as Formed between two metals.
Carbon and fluorine -polar covalent bond as it is formed by equal sharing of electrons between both the atoms and there is an electronegativity difference between the two atoms.
Carbon and hydrogen --Non polar covalent bond as formed by equal sharing of electrons between both the atoms and there is no electronegativity difference between the two atoms.
Aluminum and oxygen--ionic bond as here aluminum donates its electron and oxygen receives those electrons
Silver and copper --metallic bond as Formed between two metals.
Do you still need help?!?!
A water molecule, because of its shape, is a polar molecule.
