Answer:
The correct answer is that the polar bonds are altered and the boiling point is elevated.
Explanation:
In the case of table salt mixed with water, the sodium (Na) and chlorine (Cl) atoms initially bound together in the form of a crystal are dissolved by the water molecules.
The sodium and chlorine ions are mixed uniformly with the surrounding water molecules, so that the salt dissolves in the water, forming a homogeneous mixture. Water is a polar compound, so it easily dissolves polar substances such as salts.
This raises the boiling point of the water, as it is more difficult to break the bonds of the solution.

Answer:
The second ionization energy of an atom is always greater than its first ionization energy.
Explanation:
<em>Ionization energies are always negative quantities.</em> FALSE. Ionization energies are always positive because they represent the energy that has to be added to a neutral gaseous atom to remove 1 electron. By convention, energy absorbed goes with the positive sign.
X(g) + 1 I.E. ⇒ X(g)⁺ + 1 e⁻
<em>Oxygen has a larger first ionization energy than fluorine.</em> FALSE. First ionization energy (1 I.E) is the energy required to remove 1 electron from a neutral gaseous atom. First ionization energy for Oxygen is 13.61 eV and for Fluorine is 17.42 eV, that is, more energy is required to remove an electron from F than from O.
<em>The second ionization energy of an atom is always greater than its first ionization energy.</em> TRUE. The energy required to remove 1 electron from a +1 cation (second ionization energy) is always greater than the first ionization energy because of the attraction between the cation and the electron.
X(g)⁺ + 2 I.E. ⇒ X(g)⁺² + 1 e⁻
<em>The third ionization energy is the energy needed to ionize three electrons from a neutral atom.</em> FALSE. The third ionization energy (3 I.E.) is the energy required to remove 1 electron from a +2 cation.
X(g)⁺² + 3 I.E. ⇒ X(g)⁺³ + 1 e⁻
Answer: Answer is in Explanation
Explanation:
The strong nuclear force pulls together protons and neutrons in the nucleus. At very small distances only, such as those inside the nucleus, this strong force overcomes the electromagnetic force, and prevents the electrical repulsion of protons from blowing the nucleus apart.
