Concept explainers
Interpretation: The following reagent should be identified which can oxidase
Concept Introduction:
Redox reaction are those in which oxidation number changes.
Half reaction are the separated
Redox equation can be balanced via the half –reaction methods, which allows for the addition of
Standard EMF:
The electromotive force (EMF) is the maximum potential difference between two electrodes of a galvanic cell.
This quantity is related to the tendency for an element.
i.e- It has a great tendency to acquire or gain the compound.
Half-cell Reaction: A half-cell is one of the two electrodes in a galvanic cell.
Example, the Zn-Cu battery, the two half cells make an oxidizing couple.
Electrochemical cell:
An electrochemical cell in which a spontaneous
To identify: The following reagent which is responsible to convert water molecule into oxygen molecule.

Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry. Which molecule is the more stable molecule, and why?arrow_forward
