Answer:
Sodium chloride
Explanation:
There are several salts in seawater, but the most abundant is ordinary table salt or sodium chloride (NaCl). Sodium chloride, like other salts, dissolves in water into its ions, so this is really a question about which ions are present in the greatest concentration. Sodium chloride dissociates into Na+ and Cl- ions.
disproportionation of Br₂ in excess OH⁻ to Br⁻ and BrO₃⁻.
Br₂ + OH⁻ → Br⁻ , BrO₃⁻ + H2O
A halogen (X₂) disproportionates in the base in several steps to X⁻ and XO₃⁻.X₂ → X⁻ , XO₃⁻,
One chemical of intermediate oxidation state transforms into two compounds, one of higher and one of lower oxidation levels, in a redox reaction known as disproportionation, sometimes known as dismutation. More broadly, the word can be used to describe any desymmetrizing reaction of the form 2 A A' + A", regardless of whether it belongs to the redox family of processes or not.

Answer: the correct option is 1 (It ensures that the ester is uncharged and therefore insoluble in water so that the product can be filtered.)
Explanation:
Esters are formed through a process known as esterification. This involves the heating of a carboxylic acid with an alcohol while the water formed is continuously removed. In order for the reaction to occur at a maximum rate, an acidic catalyst is used. The most common acid catalysts includes:
- hydrochloric acid and
-sulfuric acid.
These catalyst needs to be neutralized in order to isolate the product. This is so because the solution begins to precipitate when the reaction mixture is neutralized.
Thus it is important neutralize the moisture in order to filter out the ester from the mixture, which otherwise will be in a dissolved state and will not be recoverable.
Molar mass Na = 23 g/mol
23 g ------------- 6.02 x 10²³ atoms
4.56 x 10⁻² g ----- ? atoms
atoms = 4.56 x 10⁻² x ( 6.02 x 10²³ ) / 23
atoms = 2.74 x 10²² / 23
= 1.19 x 10²¹ atoms
