question 36

Multiple Choice

Write a balanced chemical equation for the overall reaction represented below. Pt | Fe²⁺,Fe³⁺ || Cl− | AgCl | Ag

• A) AgCl(s)+ Fe³⁺(aq)+ 2e− → Ag(s)+ Fe²⁺(aq)+ Cl−(aq)
• B) AgCl(s)+ Fe³⁺(aq)→ Ag(s)+ Fe²⁺(aq)+ Cl−(aq)
• C) AgCl(s)+ Fe²⁺(aq)→ Ag(s)+ Fe³⁺(aq)+ Cl−(aq)
• D) Ag(s)+ Fe³⁺(aq)+ Cl−(aq)→ AgCl(s)+ Fe²⁺(aq)
• E) Ag(s)+ Fe²⁺(aq)+ Cl−(aq)→ AgCl(s)+ Fe³⁺(aq)

Definitions:

SCN

Short for Suprachiasmatic Nucleus, a region in the brain responsible for controlling circadian rhythms.

Suprachiasmatic Nucleus

A small region in the brain located in the hypothalamus, responsible for controlling circadian rhythms.

Intergeniculate Leaflet

The intergeniculate leaflet is a small structure located between the lateral geniculate nucleus of the thalamus, involved in regulating circadian rhythms and visually related information processing.

Retinohypothalamic Tract

Neural route formed by axons of photosensitive retinal ganglion cells (pRGCs) from the retina to the suprachiasmatic nucleus; allows light to entrain the SCN’s rhythmic activity.
