7.4: Frost Diagrams
Figure 7.4.9. (a) Frost diagram for Cr in acidic solution showing that the Cr 3+ redox state lies below a tie-line between the Cr 2+ and Cr 4+ states. (b) The slope of the green line connecting the Cr 2+ and Cr 3+ states is less than that of the pink line connecting the Cr 3+ and Cr 4+ states.
4.6: Pourbaix Diagrams
We saw a simple example of such a diagram in section 4.2 for H 2 O. Typically, the water redox reactions are plotted as dotted lines on these more complicated diagrams for other elements. The lines in Pourbaix diagrams represent redox and acid-base reactions, and are the parts of the diagram where two species can exist in equilibrium.

A Lewis electron dot diagram (or electron dot diagram, or a Lewis diagram, or a Lewis structure) is a representation of the valence electrons of an atom that uses dots around the symbol of the element. The number of dots equals the number of valence electrons in the atom. These dots are arranged to the right and left and above and below …
Hearing aid structure diagram – main components of hearing aids
The soldering point is connected to the audio signal of the hearing aid and transmitted to the coil. The coil generates a changing magnetic field to cause the vibration of the reed. This vibration is transmitted to the diaphragm through the ejector pin. The vibration of the membrane causes the air chamber in the upper part to resonate to emit a ...

PN Junction
Definition: A P-N junction is an interface or a boundary between two semiconductor material types, namely the p-type and the n-type, inside a semiconductor. In a semiconductor, the P-N junction is created by the method of doping. The p-side or the positive side of the semiconductor has an excess of holes, and the n-side or the …
Mirage
Mirage. A mirage is an optical phenomenon in which a distant object appears to be present, even though it is not actually there. The refraction of light rays causes this optical illusion as they pass through layers of air with varying densities, resulting in a deceptive appearance. For instance, in certain conditions, when the air rapidly cools ...
7.2 Lewis Dot Structures – Introduction to Chemistry
A Lewis dot structure is a representation of the valence electrons of an atom that uses dots around the symbol of the element. The number of dots equals the number of valence …

Hearing Aid Components
Hearing aids amplify sound through a three-part system: First, the microphone receives the sound and converts that sound into a digital signal. Then, the amplifier boosts the strength of the digital signal. Finally, the speaker sends the amplified sound into the ear.

Unified Modeling Language (UML) Diagrams
Unified Modeling Language (UML) is a general-purpose modeling language. The main aim of UML is to define a standard way to visualize the way a system has been designed. It is quite similar to blueprints used in other fields of engineering. UML is not a programming language, it is rather a visual language. We use UML diagrams to portray …
A Labelled Diagram Of Meiosis with Detailed Explanation
Diagram for Meiosis. Meiosis is a type of cell division in which a single cell undergoes division twice to produce four haploid daughter cells. The cells produced are known as the cells or gametes (sperms and egg). The diagram of meiosis is beneficial for class 10 and 12 and is frequently asked in the examinations.

4 Levels of Protein Structure (With Diagram)
The acidic amino acid aspartic acid has the following zwitterionic form: In this case, aspartic acid bears one positive charge and two negative charges and thus has a net charge (i.e., -1). Glutamic acid behaves in a similar manner. Finally, the basic amino acid lysine yields the following zwitterion in solution:
What is Block Diagram – Everything You Need to Know
A block diagram is a drawing illustration of a system whose major parts or components are represented by blocks. These blocks are joined by lines to display the relationship between subsequent blocks. We use block diagrams to visualize the functional view of a system.
