Le Chatelier's principle

Buffer Systems As humans, we constantly need to regulate our bodily pH. This regulation process is called homeostasis, and is controlled by the hypothalamus and pituitary gland by a buffering system. A buffer solution is used to maintain the pH at a safe acidity. “A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid” (Boundless, 2010) Equation 1 – Generic Buffer Equation HA (aq) + H2O (l) --> H3O+(aq) + A-(aq) Note that equation 1 is reversible, and all equations that are reversible have to be at a state of.equilibrium. This brings us to the Le Chatelier’s principle, of “Restoring Balance” Le Chatelier’s principle states that if a.constraint (such as a change in pressure, temperature, or concentration of a reactant) is.applied to a system at equilibrium, the equilibrium.will shift so as to.counteract the effect of the constraint. This is an extremely important function to keep all features at equilibrium, and in this case, optimum pH.…

there is enough of CO and H2O to fulfill the necessary reactions. Adding water vapor will cause the reaction quotient to shrink, and again become smaller than the equilibrium constant. The reaction creating more products will speed up, as there is more H2O that needs to be removed in order to counter the change, as described in Le Chatelier’s Principle. This is essentially caused by H2O having more chances to randomly collide with CO, increasing the probability of the reaction forming H2 and…

the appropriate information. “Organization can make the It is very common around the world that many providers always make a mistake when they prescribe drugs. I believe this is occurring again and again due to the design of the system that they are using. Using the principles of usability would prevent such errors in the future. “Usability is one of the most important factor hindering widespread adoption of EMRs”. ( Healthcare Information and Management Systems Society, 2009) The key principles…

The Six Principles of Persuasion. “Persuasion is the act or process of presenting arguments to move, motivate, or change the audience” [1] There are six known principles of persuasion, as follows: 1 – Principle of Reciprocity: is the idea of giving back, being kind, and the same time expecting to cause an effect that will reciprocate the same action back. An example is when a waitress smile a lot, act pleasantly when helping customer, mostly likely she would get a better tip, as a…

Nowadays, Benevolence is not a word used often, or maybe even at all. But there are still examples of what it means to be benevolent every day around us through different people and acts of kindness every day. And yes, even if most people can not spell it, it is still very important to use on a daily basis. However, even if one is benevolent that does not mean it is okay to act in a ‘better than thou’ or in any way all high and mighty in any way. Acting in such a manner is the complete opposite…

Freedom of speech was one of the first major principles written in the constitution. A common misconception of freedom of speech is that it has no limitations, however, when this speech breeds hatred, questions rise about bans and restrictions. When harm becomes involved, the issue of hate speech is often debated. The harm principle is the only purpose for with it is morally legitimate for government or public opinion to interfere with anyone’s liberty of action (including speech) is to prevent…

It seem difficult most of the time to find the best way to succeed in persuading your listeners. The text book offered us with about six principles that are believed to be effective in achieving the goal of successfully persuading our/your listeners which are reciprocity, scarcity, authority, commitment and consistency, consensus and liking. The identification and understanding of where each principle fit environmentally will assist …

4.) The concept of a “harm of deprivation” would be that it means the harm of death, it doesn't harm the person by causing her to be in a bad state, it harms the person by depriving her of bad things. Being dead is not like being in pain, you cant suffer if you’re dead. Death is not an ordinary harm, an ordinary harm for example would be if someone were to break your arm, they harm you because they cause you to be in a certain state: pain. Harm of deprivation means you are depriving someone…

got criticized in different ways and also a love hate relationship towards this project. 20th century architect did not accept the concept and futurist ideas that he created however in 21st century Farnsworth House have been declared as a masterpiece of modern architecture. Architecture create different ranges of forms purely by using his spirit as well as prioritising human’s ability to connect with the look, feel and shape of the form where the focus point is on the building each masterpiece…

writes or, as I apply it in this paper, the architect builds, is an aesthetic and ethical choice based on their formal approach in treating the material. Material The material is an embodied evidence of culture. Its investigation helps to trace the early stage of development and proliferation of certain ideas. Soviet new architecture is known for its material: reinforced concrete. Concrete had its long history, but it was long forgotten after the Roman Empire fall. It was rediscovered by…
