answer is: O
o goes from 0 to -2, so it is the element that is reduced

Answer:
3.47 x 10⁻⁹.
Explanation:
- The concentration of OH⁻ = 0.16 M.
∵ [OH⁻] = √(Kb)(C).
Kb for ammonia = 1.8 x 10⁻⁵.
∴ [OH⁻] = √(Kb)(C) = √(1.8 x 10⁻⁵)(0.16 M) = 2.88 x 10⁻⁶ M.
<em>∵ [H⁺][OH⁻] = 10⁻¹⁴.</em>
∴ [H⁺] = 10⁻¹⁴/[OH⁻] = 10⁻¹⁴/(2.88 x 10⁻⁶) = 3.47 x 10⁻⁹ M.
<em>∵ pH = - log[H⁺]</em> = - log(3.47 x 10⁻⁹) = <em>8.459 ≅ 8.46.</em>
Hi friend
