Thermodynamic activity
In chemical thermodynamics, activity (symbol a) is a measure of the “effective concentration” of a species in a mixture, in the sense that the species' chemical potential depends on the activity of a real solution in the same way that it would depend on concentration for an ideal solution.
By convention, activity is treated as a dimensionless quantity, although its value depends on customary choices of standard state for the species. The activity of pure substances in condensed phases (solid or liquids) is normally taken as unity (the number 1). Activity depends on temperature, pressure and composition of the mixture, among other things. For gases, the activity is the effective partial pressure, and is usually referred to as fugacity.
The difference between activity and other measures of composition arises because molecules in non-ideal gases or solutions interact with each other, either to attract or to repel each other. The activity of an ion is particularly influenced by its surroundings.

Etymology of chemistry
In the history of science, the etymology of the word chemistry is debatable. It is agreed that the word derives from the word alchemy, which is a European one, derived from the Arabic al-kīmīā (الكيمياء). The Arabic term is derived from the Greek χημία or χημεία. However, the ultimate origin of the root word, chem, is uncertain.
According to the Oxford English Dictionary, the majority theory is that al-kīmīā is derived from χημία, which is derived from the ancient Egyptian name of Egypt (khem, khame, or khmi, meaning "black earth", contrasting with the surrounding desert.) Therefore, alchemy is the "Egyptian art". However, it is also possible that al-kīmīā derived from χημεία, meaning "cast together".
Traditionally, the science of alchemy was once considered to have sprung from great Egyptian figure named by the Greeks "Hermes Trismegistus" (the "thrice-great" Hermes, celebrated as priest, king, and scholar), who is thought to have been the founder of the art. Reputed to have lived about 1900 BC, he was highly celebrated for his wisdom and skill in the operations of nature. In 1614 Isaac Casaubon demonstrated that the works attributed to Hermes – the so-called "Hermetic corpus" – were actually written pseudonymously during the first three centuries of the Common Era.

List of The New Batman Adventures episodes
Three years after the second season of Batman: The Animated Series ended production, the show was moved (as The New Batman Adventures) from Fox to The WB channel, which was airing and producing Superman: The Animated Series. These shows were merged as part of an hour-long segment called The New Batman/Superman Adventures. The WB wanted more episodes of Batman, so 24 new episodes were produced, which featured a different format and more focus on Batman's supporting cast.
In addition to the network's demands, the producers decided to make the show match the graphic style of Superman: The Animated Series, so all the characters and objects were redesigned as more "animation friendly" with fewer lines, usually referred to by the fans and creative staff as the "revamp" (or alternately, the "new look"). A similar graphic style was used in the rest of the DCAU later on.
The DVD box set of the series is labeled Batman: The Animated Series – Volume Four (from The New Batman Adventures), most likely to establish the connection with the original series.

Chemistry (TV series)
Chemistry was a comedy-drama series that debuted on Cinemax as a part of its Max After Dark lineup on August 19, 2011. It followed the affair of an attorney and a police officer, which began after the officer saved the attorney from a car wreck. The last episode aired on November 18, 2011.

List of Death Note episodes
Death Note is a 37-episode anime series based on the manga series of the same title written by Tsugumi Ohba and illustrated by Takeshi Obata. Death Note aired in Japan on the Nippon Television (NTV) network every Tuesday, from October 3, 2006, to June 26, 2007. The plot of the series primarily revolves around high school student Light Yagami, who decides to rid the world of evil with the help of a supernatural notebook titled Death Note. This book causes the death of anyone whose name is written in it and is passed on to Light by the God of Death (or Shinigami) Ryuk after he becomes bored within the Shinigami world.
A three-hour "Director's Cut" compilation TV special, titled "Death Note: Relight: Visions of a God", aired on NTV a few months after the anime concluded. Although advertised to be the "complete conclusion", the popularity of the series inspired the release of a second TV special, titled "Death Note: Relight 2: L's Successors" nearly a year later. These specials recap the first and second arcs of the anime respectively, with new scenes added to fill in any plot holes resulted from omitted footage.

Task (project management)
In project management, a task is an activity that needs to be accomplished within a defined period of time or by a deadline to work towards work-related goals. A task can be broken down into assignments which should also have a defined start and end date or a deadline for completion. One or more assignments on a task puts the task under execution. Completion of all assignments on a specific task normally renders the task completed. Tasks can be linked together to create dependencies.
Tasks completion generally requires the coordination of others. Coordinated human interaction takes on the role of combining the integration of time, energy, effort, ability, and resources of multiple individuals to meet a common goal. Coordination can also be thought of as the critical mechanism that links or ties together the efforts on the singular level to that of the larger task being completed by multiple members. Coordination allows for the successful completion of the otherwise larger tasks that one might encounter.

Radioactive decay
Radioactive decay, also known as nuclear decay or radioactivity, is the process by which a nucleus of an unstable atom loses energy by emitting radiation. A material that spontaneously emits such radiation — which includes alpha particles, beta particles, gamma rays and conversion electrons — is considered radioactive.
Radioactive decay is a stochastic (i.e. random) process at the level of single atoms, in that, according to quantum theory, it is impossible to predict when a particular atom will decay. The chance that a given atom will decay never changes, that is, it does not matter how long the atom has existed. For a large collection of atoms however, the decay rate for that collection can be calculated from their measured decay constants or half-lives. This is the basis of radiometric dating. The half-lives of radioactive atoms have no known limits for shortness or length of duration, and range over 55 orders of magnitude in time.
There are many different types of radioactive decay (see table below). A decay, or loss of energy from the nucleus, results when an atom with one type of nucleus, called the parent radionuclide (or parent radioisotope), transforms into an atom with a nucleus in a different state, or with a nucleus containing a different number of protons and neutrons. The product is called the daughter nuclide. In some decays, the parent and the daughter nuclides are different chemical elements, and thus the decay process results in the creation of an atom of a different element. This is known as a nuclear transmutation.

Activity
For a non-ideal solution, we can use the activity of a component to describe its effective concentration. This allows us to continue using many of the equations that were derived under ideal conditions, even for non-ideal solutions.

Activity Coefficient
The activity coefficient describes the degree to which a component of a solution behaves ideally. The activity coefficient is 1 for an ideal solution. The activity coefficient is greater than one for a component that exhibits positive deviations from Raoult's Law, and less than one if it exhibits negative deviations.

For a non-ideal solution, we can use the activity of a component to describe its effective concentration. This allows us to continue using many of the equations that were derived under ideal conditions, even for non-ideal solutions.

The activity coefficient describes the degree to which a component of a solution behaves ideally. The activity coefficient is 1 for an ideal solution. The activity coefficient is greater than one for a component that exhibits positive deviations from Raoult's Law, and less than one if it exhibits negative deviations.

This chemistry video tutorial explains the activity series of metals and elements such as hydrogen. It shows you how to tell if a single replacement reaction will work or if there will be no reaction using the activity series chart. It also shows you how to write the net ionic equation of a single replacement reaction. In addition, this video also helps you to identify which metals are strong reducing agents and which metal cations are oxidizing agents. Finally, it mentions which metals are active or reactive and which ones are nonreactive or chemically inert.

Thermodynamic activity
In chemical thermodynamics, activity (symbol a) is a measure of the “effective concentration” of a species in a mixture, in the sense that the species' chemical potential depends on the activity of a real solution in the same way that it would depend on concentration for an ideal solution.
By convention, activity is treated as a dimensionless quantity, although its value depends on customary choices of standard state for the species. The activity of pure substances in condensed phases (solid or liquids) is normally taken as unity (the number 1). Activity depends on temperature, pressure and composition of the mixture, among other things. For gases, the activity is the effective partial pressure, and is usually referred to as fugacity.
The difference between activity and other measures of composition arises because molecules in non-ideal gases or solutions interact with each other, either to attract or to repel each other. The activity of an ion is particularly influenced by its surroundings.
