question 61

Multiple Choice

Calculate the molar concentration of uncomplexed Zn²⁺(aq) in a solution that contains 0.17 M Zn(NH₃) ₄²⁺ and 0.3775 M NH₃ at equilibrium. K_f for Zn(NH₃) ₄²⁺ is $2.9 \times 10 ^ { 9 }$ .

• A) \(2.9 \times 10 ^ { - 9 }\) M
• B) \(1.6 \times 10 ^ { - 10 }\) M
• C) \(3.5 \times 10 ^ { 8 }\) M
• D) \(4.1 \times 10 ^ { - 10 }\) M
• E) \(2.7 \times 10 ^ { 0 }\) M

Definitions:

Recessive Traits

Genetic characteristics that are expressed in offspring only when two copies of the gene are present, one from each parent.

Dosage Compensation

A mechanism that ensures equal expression of genes from the sex chromosomes despite the difference in chromosome number between males and females.

X-Linked Gene

A gene located on the X chromosome, with its expression and associated traits often differentially presented in males and females due to X-chromosome inactivation or hemizygosity in males.

Independent Assortment

The principle describing how different genes independently separate from one another when reproductive cells develop.
