question 104

Multiple Choice

Which statement is true regarding the reversible reaction below? H₂CO₃+ F^-
HCO₃+ HF.
K_a1(H₂CO₃) = 4.2 × 10^-7; K_a(HF) = 7.1 × 10^-4

• A) At equilibrium, [HF] > [H₂CO₃] because HF is a stronger acid than H₂CO₃.
• B) At equilibrium, [HF] > [H₂CO₃] because H₂CO₃ is a stronger acid than HF.
• C) At equilibrium, [HF] = [H₂CO₃].
• D) At equilibrium, [H₂CO₃] > [HF] because HF is a stronger acid than H₂CO₃.
• E) At equilibrium, [H₂CO₃] > [HF] because H₂CO₃ is a stronger acid than HF.

Definitions:

Fertilized Egg

A cell formed by the combining of a male and female gamete (sperm and egg) which then begins cell division to develop into an embryo.

Gametes

Reproductive cells (sperm in males and eggs in females) that carry half the genetic information of an individual and can combine to form a new organism.

Zygotes

The initial cell formed when a new organism is produced by the union of sperm and egg cells, representing the earliest developmental stage of the embryo.

Alleles

Different versions of a gene that determine distinct traits that can be passed from parents to offspring.
