Answer:
The eight protons in oxygen atom's nucleus will exert more force than nitrogen's seven electrons. Also, oxygen has same number of shells as nitrogen. Thus electrons in oxygen atom will be closer to nucleus than in the case of nitrogen. When electrons are closer it means atomic radius is smaller.
Hope this helps! :)

Answer:
The correct answer is c. the acetate ion acts as a Bronsted-Lowry base in a reaction with water.
Explanation:
Sodium acetate (NaCH₃COO) dissociates in water to give Na⁺ and CH₃COO⁻ ions as follows:
NaCH₃COO(s) → Na⁺(aq) + CH₃COO⁻(aq)
The acetate ion (CH₃COO⁻) is the conjugated base of acetic acid (CH₃COOH). Acetic acid is a weak acid, so the acetate ion will try to regenerate the weak acid. For this, it will acept a proton (acting as a Bronsted-Lowry base) from water to form acetic acid. As result, OH⁻ is released and the solution turns basic:
CH₃COO⁻(aq) + H₂O(l) ⇄ CH₃COOH(aq) + OH⁻(aq)
