The answer is a. First, do the ones in the brackets and then follow with the multiplication
Answer:
Explanation:
There are principles that guides the distribution of electrons into the energy levels in an atom. Some of the principles are:
1. The maximum number of electrons in the orbitals of sublevels are:
2 electrons for s-sublevel with one orbital
6 for p-sublevel with 3 orbitals
10 for d- sublevel with 5 orbitals
14 for f-sublevel with 7 orbitals.
The maximum number of electrons in an orbital is 2.
2. Aufbau principle: it states that sublevels with lower energy are filled up before those with higher energy. Sublevels have pattern of filling.
3. Pauli exclusion principle: it states that no two electrons can have the same set of the four quantum numbers.
4. Hund's rule of maximum multiplicity: electrons goes into degenerate orbitals of sub-levels singly before pairing starts.

See the explanation
Explanation:
In this case, we have to remember that in the <u>monochlorination products</u> we only have to add one "Cl" with this in mind, we can have several options.
<u>a) 1-chloro-2,2-dimethylbutane</u>
<u>b) (R)-3-chloro-2,2-dimethylbutane</u>
<u>c) (S)-3-chloro-2,2-dimethylbutane</u>
<u>d) 1-chloro-3,3-dimethylbutane</u>
Additionally, from these 4 molecules, we will have 2 enantiomers. (R)-3-chloro-2,2-dimethylbutane and (S)-3-chloro-2,2-dimethylbutane.
See figure 1

Answer: The basicity of the salt anion
Explanation:
All the weak acid is neutralized at the equivalence point and transferred to its conjugate base (number of moles of H+ = increased number of moles of OH–). Therefore the solution produced is weakly alkaline and the pH of the equivalence point will be greater than 7.
