The statement correct about bonding is the release of energy in bond formation, and is exothermic. Thus, option C is correct.
The bonds have been defined as the sharing of electrons between atoms for the stabilization and forming compounds. The formation and breaking of the bond results in the absorption and release of the energy.
<h3>Endothermic and Exothermic reaction</h3>
The reaction in which the energy has been released has been termed as exothermic reaction. The reaction in which energy is absorbed is termed as endothermic system.
The bonds are stable, and to break the bond energy has to be provided to the system. The energy will result in the delocalization of electrons and thereby breaking of bonds.
Since energy has been absorbed by the system during breaking of bonds, the reaction has been an endothermic reaction.
The formation of the bond has been releases the energy in the system and is an exothermic reaction. Thus, option C is correct.

Answer:
15. 2.66 moles .
16. 2.09L.
Explanation:
Molarity of a solution is simply defined as the mole of solute per unit litre of the solvent. Mathematically, it is represented as:
Molarity = mole /Volume.
With the above formula, let us answer the questions given above
15. Data obtained from the question include the following:
Volume of solution = 1.4L
Molarity = 1.9M
Mole of solute =.?
Molarity = mole /Volume
1.9 = mole / 1.4
Cross multiply
Mole = 1.9 x 1.4
Mole = 2.66 moles
Therefore, the mole of the solute present in the solution is 2.66 moles.
16. Data obtained from the question include the following:
Mole of solute = 0.46 mole
Molarity = 0.22M
Volume of solvent (water) =.?
Molarity = mole /Volume
0.22 = 0.46/Volume
Cross multiply
0.22 x Volume = 0.46
Divide both side 0.22
Volume = 0.46/0.22
Volume = 2.09L
Therefore, 2.09L of water is required.
