Dead Poets Society is a 1989 film that tells the story of a group of young boys at an all-boys prep school in the 1950s. The film follows the story of John Keating, an unorthodox English teacher who inspires his students to think for themselves and to seize the day. One of Keating's students, Neil Perry, is particularly moved by Keating's teachings and begins to challenge the strict rules and expectations of his privileged and controlling father. Tragically, Neil ultimately takes his own life, unable to reconcile his desire for personal freedom and self-expression with the rigid expectations and demands placed upon him by his father and society.
Neil's suicide serves as a poignant reminder of the dangers of conformity and the importance of individual expression. Throughout the film, Neil is shown struggling to find his own voice and to assert his own identity in the face of overwhelming pressure to conform to societal expectations. His father, a wealthy and successful businessman, expects Neil to follow in his footsteps and become a doctor, despite Neil's deep passion for acting.
Despite his initial resistance, Neil ultimately succumbs to the pressure and enrolls in pre-med courses, much to the delight of his father. However, as Neil becomes more involved in the Dead Poets Society, a secret club founded by Keating that encourages its members to think for themselves and to challenge the status quo, he begins to feel more confident in his own desires and opinions. He eventually stands up to his father and declares his intention to pursue a career in acting, a decision that ultimately leads to his suicide.
Neil's suicide is a tragic and devastating outcome, but it serves as a powerful reminder of the importance of standing up for oneself and following one's own passions and desires, even in the face of societal expectations and pressures. It is a reminder that conformity can be deadly, and that it is essential to find and embrace one's own individuality and authenticity, no matter the cost.

Predicting the Feasibility of a Redox Reaction: Depending on the E° values of the two electrodes feasibility of the given redox reaction can be found out. We call the potential difference between a half-cell and the reference hydrogen electrode under standard conditions the cell's standard electrode potential. Electrochemical series Amassing the standard electrode potentials of different elements creates the electrochemical series. Find the cell potential at standard conditions. For Choosing Elements as Reducing Agents: The elements which have more electron losing tendency are reducing agents.
Thus, we can tell if a redox reaction can proceed spontaneously by examining the reactants and products. Alkali metals and alkaline metals at the bottom are highly reactive. Comparison of the reactivity of different metals As a matter of fact, the oxidation or reduction of various substances and ions are known through the electrochemical series. On the other hand, the substances at the bottom of the table have higher reduction potential, therefore they have the least tendency to get oxidized. In general, a more electronegative element takes electrons from a more electropositive one. The applications of electrochemical series are shown below. Al, Zn, Fe, Ni, Co, etc.
Therefore, the elements at the top of the table have a maximum tendency to get oxidized and consequently, they will act as good reducing agents. To predict whether a metal can or can not displace another metal in a salt solution The metal which is less electropositive than the metal present in the salt solution can displace metal from its salt. They can react with cold water and evolve hydrogen. For Example, F2 electrode with the standard reduction potential value of +2. He is doing his integrated masters in Physics. It is based on nothing more than simple more negative potential difference than copper, there is a greater build-up of electrons on the zinc rod.
The element like Zn, Cd, Ni, K, etc. Calculation of the EMF of the Cell: If the EMF of the cell is positive, the reaction is feasible in the given direction and the cell is correctly represented. Displacement of hydrogen from water: Iron and the metals below iron are capable of liberating hydrogen from water. To predict the feasibility of the reaction To predict the feasibility of the reaction, the emf of a cell can be calculated. Oxidizing power decreases from top to bottom in the series. The electrochemical series gives the increasing order of electrode potential reduction of different electrodes on moving down the table.

Zinc atoms turn into zinc ions, losing electrons; copper ions turn into copper atoms, gaining electrons. Why are elements at the bottom of an electrochemical series reduce agents? Reducing strength goes on increasing from top to bottom in the series. B Less Hydrogen gas is evolved. Post navigation Acharya Samudra studies at University of Hyderabad. Characteristics of Electrochemical Series hydrogen in the series and have negative values of standard reduction potentials.
For Corrosion Treatment: When two metals which are in contact with each other are exposed to the atmosphere, the element lower in series will be oxidized. Displacement reactions: A metal higher in the series will displace the metal from its solution which is lower in the series. So, when such a metal is placed in an acid solution, the metal gets oxidized, and H +ions get reduced to form hydrogen gas. In a mixture of copper and silver ions, silver will be deposited first because the reduction potential of silver is higher than copper. For example, batteries are important not only in storing energy for mobile devices and vehicles, but also for load leveling to enable the use of renewable energy conversion technologies. Comparison of Reactivities of Metals: The relative ease with which the various species of metals and ions may be oxidized or reduced is indicated by the reduction of potential values. In general, electrons travel from a species with a more negative standard electrode potential to a species with a more positive standard electrode potential.
Electrochemical Series: The concept and its applications
What are different types of electrochemical series? Among Zinc and copper, copper acts as a cathode whereas Zinc acts as an anode as copper has a higher reduction potential. In general, a redox reaction is feasible only if the species which has a higher reduction potential is reduced i. Reducing agents are themselves oxidised. Therefore, silver will be reduced and copper will be oxidized and the above reaction is not feasible. In the electrochemical Series, metal is located above hydrogen, compared to hydrogen. So they are good oxidizing agents. Consider zinc and copper.
Define electrochemical series and write its applications?
Complete step by step answer: The electrochemical series is defined as the arrangement of the elements in their increasing order of electrode potential values. The arrangement of elements in order of increasing reduction potential value is calledelectrochemical series. It gives an idea about which element is stronger oxidizing and which is reducing. Elements at the top of the electrochemical series have higher + ve reduction potential. So bottom elements in electrochemical series are reducing agents. Electrode potential value is calculated as follows.
