Options:
A. prototype.
B. heuristic.
C. algorithm.
D. confirmation bias.
Answer: C. Algorithm.
Explanation: Algorithm is a procedure of solving a problem by following a series of sequence that will help to solve the problems. Algorithm is applied both in the Field of Mathematics and Computer science.
Algorithm is the procedure adopted in search engines, algorithm also helps to solve recurring problems, it is a step by step approach, where each step is well thought out and has a defined pattern and approach.

Answer:
Kb = 1.6 × 10⁻⁵
Explanation:
Step 1: Given data
Acid dissociation constant of hydrocyanic acid (Ka): 6.2 × 10⁻¹⁰
Concentration of cyanide ion (Cb): 0.1 M
Step 2: Calculate the basic dissociation constant (Kb) of cyanide ion
We have the Ka of HCN. We can calculate the Kb of its conjugate base using the following expression.
Ka × Kb = Kw = 1.0 × 10⁻¹⁴
Kb = 1.0 × 10⁻¹⁴/Ka
Kb = 1.0 × 10⁻¹⁴/6.2 × 10⁻¹⁰
Kb = 1.6 × 10⁻⁵
