Reduction Half-Reactions with Corresponding Standard Half-Cell Potentials Are Shown Below

question 52

Short Answer

Reduction half-reactions with corresponding standard half-cell potentials are shown below.
Zn²⁺(aq)+ 2 e^- → Zn(s)E° = - 0.76 V
Al³⁺(aq)+ 3 e^- → Al(s)E° = - 1.66 V
The standard potential for the galvanic cell that uses these two half-reactions is ________ V.

Definitions:

Blastocyst

A blastocyst is an early stage embryo consisting of 50-150 cells in a fluid-filled sphere, instrumental in the implantation process of pregnancy.

Yolk

Yolk is the nutrient-rich material found within eggs, providing essential energy and nutrients for the developing embryo in various species.

Blastocele

Cavity in the blastocyst.

Trophoblast

Cell layer forming the outer layer of the blastocyst, which erodes the uterine mucosa during implantation; the trophoblast does not become part of the embryo but contributes to the formation of the placenta.
