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.

Essentials of physical chemistry. Both the statement 1 and statement 2 are not correct In the schematic diagram for the preparation of hydrogen gas as shown in the figure, what would happen if the following changes are made? 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. This is because in e. We can't directly measure the potential difference generated by a single half-cell. Oxidizing and Reducing Strengths Electrochemical series helps us to identify a good oxidizing agent or reducing agent.

Both assertion and reason are correct and reason is the correct explanation for assertion. We call the system created by putting a metal in a solution of its own ions a half -cell. Helps in predicting liberation of hydrogen gas from acids by metals. They have higher oxidation potential. A metal lower in the series has a greater tendency to provide electrons to the cations of the metal to be precipitated. Thus, the metals occupying lower positions in the electrochemical series readily liberate hydrogen from dilute acids and on ascending in the series tendency to liberate hydrogen gas from dilute acids decreases.

electrochemical series and its applications

To predict whether a Metal Reacts with acid to give Hydrogen Gas or not: The metal M reacts with an acid H + to give H 2 gas. Zinc atoms turn into zinc ions, losing electrons; copper ions turn into copper atoms, gaining electrons. The reaction must be occurring in the reverse direction. The electrochemical series thus can be said to be a measure of electronegative nature. For Studying displacement reaction: One metal can be displaced from a salt solution by another metal is known as a redox reaction. It also is a measure of the work that can be done by the cell. Displacement of hydrogen from water: Iron and the metals below iron are capable of liberating hydrogen from water.

Which of the following is the best oxidizing agent and which is the best reducing agent? Each half cell undergoes a reaction, one is oxidation and the other is reduction. To figure out the standard EMF of the electrochemical cell. Predicting the Liberation of Hydrogen Gas from Acids by Metals: All metals having negative electrode potentials - E° show a greater tendency of losing electrons as compared to hydrogen. This means that a better reducing agent is oxidised more easily. Electrochemical or activity series When the electrodes metals and non-metals in contact with their ions are arranged on the basis of the values of their standard reduction potentials or standard oxidation potentials, the resulting series is called the electrochemical or electromotive or activity series of the … What are three applications of electrochemical series? Displacement reactions, a metal which is placed higher in series will displace metal from its solution which is lower in series. For Example, F2 electrode with the standard reduction potential value of +2. Element F 2 at the topmost position of electrochemical series which has the highest reduction potential is the strongest oxidizing agent.

Applications of Electrochemical Series: For Choosing Elements as Oxidising Agents: The elements which have more electron-accepting tendency are oxidizing agents. Finding uniformities across nature pleases him. Electrochemical series can be used to predict which elements is more reactive and which is not. A This cell converts the electrical energy liberated during the redox reaction to chemical energy. For Construction of a Cell: Various cells can be constructed by combining standard electrodes given in EMF series as per the requirement of e.

Metals like Cu, Ag, and Au which lie above the hydrogen are less reactive and do not react with water in any form to evolve hydrogen. The elements like Cu, Ag, Hg, Br 2, Cl 2, etc. Therefore, hydrogen gas is not liberated. Predicting End-Products of a Redox Reaction If we are given only the reactants of a reaction, we can calculate the end products of the reaction as follows. Their atoms are not in a position to lose electrons to H + ions of the acid. The electrochemical series gives the increasing order of electrode potential reduction of different electrodes on moving down the table. They have a higher tendency to oxidize.

It tells us whether a reaction is feasible possible or not. On the contrary if EMF of cell is negative then redox cell reaction will be non spontaneous. The elements present at the top of the electrochemical series are considered as good oxidizing agents and those which are present below the electrochemical series are considered as good reducing agents. In general, in such competition, the ion which is the stronger oxidizing agent higher value of standard reduction potential is discharged first at the cathode. This means that we write the ions and electrons on the left-hand side and the combined element on the right-hand side. He is doing his integrated masters in Physics.

So bottom elements in electrochemical series are reducing agents. In place of zinc, copper turnings are taken. The substances which are weaker reducing agents than hydrogen are placed above the hydrogen in the series and have positive standard reduction potential. The elements at the bottom in the electrochemical series have lower - ve reduction potential. Now, consider what would happen if you put a rod of copper in a solution of copper ions.
