Study the electron dot diagrams for lithium, carbon, fluorine, and neon in Figure 6-1. Choose the statement that correctly ident
ifies the most stable of the elements.
A. Lithium is the most stable element because it has to lose only one electron to achieve a stable configuration.
B. Carbon is the most stable element because it can form four bonds.
C. Fluorine is the most stable element because it has to gain only one electron to achieve a stable configuration.
D. Neon is the most stable element because its highest occupied energy level is filled.

Answer:
Explanation:
Hello,
In this case, for a concentration of 0.42 M of benzoic acid whose Ka is 6.3x10⁻⁵ in 0.33 M sodium benzoate, we use the Henderson-Hasselbach equation to compute the required pH:
Whereas the concentration of the base is 0.33 M and the concentration of the acid is 0.42 M, thereby, we obtain:
