All of the F's sublevels, including the 5F contains 7 orbitals. Then, each orbital should contain 2 electrons. From the given above, the number of electrons in the sublevel is calculated through,
n = (7 orbitals) x (2 electrons / orbital) = 14 electrons
Thus, the 5F sublevel contains 14 electrons.
A.)
dG = -(0.008314)(348K) (1.5 * 10-5)
dG = -(0.008314)(348K (-11.107)
dG = 32 kJ/mol (rounded from 32.14)

Answer:
Ionic bonds are opposite, whereas Covalent bonds are opposite.
Explanation:
Two opposite ions attract each other and form the ionic bond. Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and othercovalent bonds.
Examples:
Sodium Chloride and Sodium Fluoride are examples of <em>Ionic</em><em> </em><em>bonds</em><em>.</em>
<u>and</u>
Water and Carbon Dioxide are examples of <em>Covalent</em><em> </em><em>bonds</em><em>.</em><em> </em>
Your answer is choice C. That is solid sodium chloride never dissolves to form sodium ions and chloride ions.
Going further to explain, have a look at the question again, we are told that James Proton prepares a saturated solution of sodium chloride in a beaker by adding solid sodium chloride and stirring.
Then when James finishes, crystals of sodium chloride are observed at the bottom of the beaker.
This implies that no more salt was dissolving since the saturation point was reached.
Again suppose he increased the temperature of the reaction, more salts could have dissolved.
