Answer:
D) The carbon in the carboxylic acid is sp2 hybridized and has a higher percent s-character that shortens the C-O bond in the carboxylic acid.
Explanation:
The central carbon atom in acetic acid posses sp2 hybridization and the central carbon atom in ethanol posses sp3 hybridization. As the percent s-character in sp2 hybridized carbon atom is 33% whereas in sp3 hybridized carbon atom ther percent s-character is 25%. Higher is the s-character higher is the electronegativity and stronger is the tendency to pull shared pair of electron towards itself and thus, making the bond shorten and stronger. Thus, the carbon-oxygen single bond in acetic acid becomes short due to sp2 hybridization.
Therefore, option (D) is correct that the carbon in the carboxylic acid is sp2 hybridized and has a higher percent s-character that shortens the C-O bond.

Answer:
1.39x10⁻⁶ mol
Explanation:
First we <u>convert the gallon of juice to liters</u>:
Then we <u>calculate the mass of antimony that would be in 3.785 L</u>, using the <em>given concentration</em>:
- 44.7 μg/L * 3.785 L = 169.2 μg
Then we <u>convert mass into moles</u>, using the <em>molecular mass</em>:
- 169.2 μg ÷ 121.76 μg/μmol = 1.39 μmol
Finally we <u>convert μmol into mol</u>:
- 1.39 μmol = 1.39x10⁻⁶ mol
