Answer:
a. The resonance effect of the hydroxyl group stabilizes the anionic intermediate
Explanation:
The resonance effect stabilizes the the charge through the delocalization of the pi bonds. The resonance stabilization mainly occurs in the conjugated pi systems.
For example, phenol forms a strong hydrogen bonds than the nonaromatic alcohols as the 
dipole present in the hydroxyl group is being stabilized by the presence of the aromatic ring of phenol.
Thus the resonance effect of the hydroxyl group stabilizes the anionic intermediate.
Answer:
pH = 5.58
Explanation:
Given that :
Citric acid is a triprotic acid with the formula 
. Tripotic acids are acids that have the tendency to yield three protons per molecule during the phases of dissociation, therefore they have three pka.
For Citric acid; the pka values are:
So, the pH of sodiummonohydrogencitrate with the chemical formula 
which can act as an acid and a base (i.e it is said to be amphoteric) can be calculated as :
pH = 5.58
Therefore, the approximate pH of a solution of sodium monohydrogencitrate = 5.58
Answer: SO2(Sulfur Dioxide) Molecular Geometry & Lewis Structure
Explanation: So2Molecular Geometry
We know that the shape which minimizes the repulsions of electronics pairs is adopted by the molecule to form the structure. The molecular shape of SO2 is same as the molecular geometry of Carbon Dioxide (CO2). We will show the bonding of SO2 without making assumption below.
O =S =O
I would say that the bacteria who live inside one's gut would constitute very small organisms that are extremely small and inhabit the gut as home and also feed off it to survive and in this case probably have a symbiotic relationship with our bodies as they help us to break down and digest food.
