How to Make Water From Hydrogen and Oxygen

How to Make Water From Hydrogen and Oxygen Water is the common name for dihydrogen monoxide or H2O. The molecule is produced from numerous chemical reactions, including the synthesis reaction from its elements, hydrogen, and oxygen. The balanced chemical equation for the reaction is: 2 H2 O2 → 2 H2O How to Make Water In theory, its easy to make water from hydrogen gas and oxygen gas. Mix the two gases together, add a spark or sufficient heat to provide the activation energy to start the reaction, and presto- instant water. Merely mixing the two gases at room temperature, however, wont do anything, like hydrogen and oxygen molecules in the air dont spontaneously form water. Energy must be supplied to break the covalent bonds that hold H2 and O2Â  molecules together. The hydrogen cations and oxygen anions are then free to react with each other, which they do because of their electronegativity differences. When the chemical bonds re-form to make water, additional energy is released, which propagates the reaction. The net reaction is highly exothermic, meaning a reaction that is accompanied by the release of heat. Two Demonstrations One common chemistry demonstration is to fill a small balloon with hydrogen and oxygen and to touch the balloon- from a distance and behind a safety shield- with a burning splint. A safer variation is to fill a balloon with hydrogen gas and to ignite the balloon in the air. The limited oxygen in the air reacts to form water but in a more controlled reaction. Yet another easy demonstration is to bubble hydrogen into soapy water to form hydrogen gas bubbles. The bubbles float because they are lighter than air. A long-handled lighter or burning splint at the end of a meter stick can be used to ignite them to form water. You can use hydrogen from a compressed gas tank or from any of several chemical reactions (e.g., reacting acid with metal). However you do the reaction, its best to wear ear protection and maintain a safe distance from the reaction. Start small, so that you know what to expect. Understanding the Reaction French chemist Antoine Laurent Lavoisier named hydrogen, Greek for water-forming, based on its reaction with oxygen, another element Lavoisier named, meaning acid-producer. Lavoisier was fascinated by combustion reactions. He devised an apparatus to form water from hydrogen and oxygen to observe the reaction. Essentially, his setup employed two bell jars- one for hydrogen and one for oxygen- that fed into a separate container. A sparking mechanism initiated the reaction, forming water. You can construct an apparatus the same way as long as you are careful to control the flow rate of oxygen and hydrogen so that you dont try to form too much water at once. You also should use a heat- and shock-resistant container. Role of Oxygen While other scientists of the time were familiar with the process of forming water from hydrogen and oxygen, Lavoisier discovered the role of oxygen in combustion. His studies eventually disproved the phlogiston theory, which had proposed that a fire-like element called phlogiston was released from matter during combustion. Lavoisier showed that a gas must have mass for combustion to occur and that the mass was conserved following the reaction. Reacting hydrogen and oxygen to produce water was an excellent oxidation reaction to study because nearly all the mass of water comes from oxygen. Why We Cant Just Make Water? A 2006 report by the United Nations estimated that 20 percent of people on the planet dont have access to clean drinking water. If its so hard to purify water or desalinate sea water, you might be wondering why we dont just make water from its elements. The reason? In a word- BOOM! Reacting hydrogen and oxygen is basically burning hydrogen gas, except rather than using the limited amount of oxygen in the air, youre feeding the fire. During combustion, oxygen is added to a molecule, which produces water in this reaction. Combustion also releases a lot of energy. Heat and light are produced so quickly that a shock wave expands outward. Basically, you have an explosion. The more water you make at once, the bigger the explosion. It works for launching rockets, but youve seen videos where that went horribly wrong. The Hindenburg explosion is another example of what happens when a lot of hydrogen and oxygen get together. So, we can make water from hydrogen and oxygen, and chemists and educators often do- in small quantities. Its not practical to use the method on a large scale because of the risks and because its much more expensive to purify hydrogen and oxygen to feed the reaction than it is to make water using other methods, to purify contaminated water, or to condense water vapor from the air.

For most of us, the future can be an uncertain entity- what our professional and personal lives will look like as the months, years, and decades roll forward can be difficult to predict, and unexpected twists and turns along the way can derail our plans and force us to revise our goals along the way. This uncertainly can cause a great deal of stress, so it makes sense to have as much under our control and working in our favor as possible. Having a financial safety net of sorts to help see us through is obviously beneficial.Have we convinced you that it’s a good idea to start gettin g your financial life in order? If so, then keep reading, and consider using the following strategies to get you started on the right path.Get seriousOne of the most important aspects of getting yourself in good financial shape is to get in the proper mindset for doing so.

Emerging Technologies - Essay Example Every company and organization has become heavily dependent on the use of technology to run business activities. For example, use of computers networks and internet has become a common thing for every organization. In this report, we will discuss an innovative technology related to the field of computer science. The name of the technology is Cloud Management Information System (Cloud MIS). Cloud MIS service refers to the use of cloud computing services for managing information provided to the system by the companies using the service. Some of the main benefits that a company can get using Cloud MIS service include secure data management, improved efficiency, lower capital expenditure, no need of hiring IT professionals to manage the MIS, greater flexibility and storage, and lower operational expenditure. The concept of this technology was developed a couple of years ago but more and more developments are occurring in this technology making it more useful and reliable for companies an d organizations. Let us first have a look at basic workings of Management Information System and Cloud Computing in order to get a better understanding of the benefits that the merger of these technologies can provide to businesses. 2. Management Information System According to Oz (2009, p. 9) states, â€Å"Information is the lifeblood of any organization†. Without information, a company can never achieve its desired goals and objectives because information serves as the base for business progress. Management information system (MIS) refers to a system that manages the data and information of a company needed to perform different business activities. MIS makes use of information technology tools in processing of information and generation of reports (Earl 1996). It is a part of internal business control system which manages the documents, business strategies and policies, and information stored in it by the company (Martin 2010). According to Stahl (2008, p. 1), management in formation systems increase the efficiency of business processes, as well as improves coordination between people within organization. As Lauderdale (n.d., p. 1) states, â€Å"MIS allows managers to create reports about the company activities†. This statement shows that MIS can be used to generate reports about business activities, such as, financial reports, employee performance reports, and project related reports. According to Lucey (2005, p. 4), the main tasks of a management information system are to process collected data into information, as well as to send accurate and relevant information to the concerned people. As Burke (n.d., p. 1) states, â€Å"MIS, or management information systems, are used to manage the data created within the structure of a particular business†. MIS stores everything related to business which also include project deadlines and employees’ tasks regarding those projects. Using the information for the system, employees carry out the ir activities accordingly. According to Currie and Galliers (1999), MIS also helps employees in processing, analyzing, and disseminating the collected information. Another advantage of using MIS in companies is that it helps in setting and achieving both short-term and long-term strategic goals and objecti

Lisa Benton Case Analysis Assignment Example | Topics and Well Written Essays - 1000 words

Lisa Benton Case Analysis - Assignment Example This report will also understand the importance of the leadership approaches in an organization and the display of different kinds of traits by the assistant product manager. The study will also give an insight to the various managerial situations that could have been managed properly and systematically by the manager to avoid confusion within the organizations. Finally, the study will conclude by suggesting certain recommendations that can also serve the purpose of a guide for future. Leadership Approach The leadership approach exhibited by Lisa Benton at multiple stages and situations is Bureaucratic leadership. Bureaucratic and Autocratic leadership style are almost similar to each other except for the fact that the employees and the team working in the organization are totally governed by rules and regulations. This leadership approach focuses on accomplishment of tasks and objectives within a stipulated time frame (Skinner, 1992).The leader understands the rules and regulations of the organization and is responsible for making the employees understand these rules. The leader is often reluctant to change and does not welcome change and development within the organization easily (Terry, 2003). ... At the present moment she has certain managerial traits which are almost similar to transactional leadership. The difference between transactional and transformational leadership is a clear example of the distinction between manager and leader. At the present moment Lisa requires a leadership approach which can serve the purpose of a guide and also help in addressing her shortcomings. As per theorist Helgesen certain feminine characteristics make the women leader advantageous than the male leaders like excellent communication skills, good listener, ability to solve potential conflict and advanced intermediary skills (Flores, Stanford & Oates, 1995). In this case power based leadership approaches can help Lisa in addressing the problems of the organization. The leadership theory proposed by French and Raven lays emphasis on the fact that leadership is a continual process and one individual should exert power over the other individual in a positive way (Flores, Stanford & Oates, 1995). Leadership theories like trait, personal behavior and contingency theory can act as catalyst in improving the efficiency of the employee and the organization. The theories laid emphasis on the fact that leadership action is interrelated to the degree of the authority vested by the manager on his subordinates. There is an existing continuum which consists of boss centered leadership approach on one side and subordinate centered leadership on the other side. This theory will help Lisa to clearly communicate her ideas and ideologies to her subordinates and her boss. Lack of Influential Power Lisa has excellent managerial traits which could not be translated into smooth

Flaws with Utilitarianism Essay Example for Free

Flaws with Utilitarianism Essay Among the most glaring problems that I see with Utilitarianism is its inclusion of animals under the umbrella that blankets this theory. It seems irrefutable that there exists an inordinate number of cases where the consequence that is against the best interest of an animal is favorable to humans, yet that dictating action is one that has been continually taken and condoned by the general public. This is a fundamental challenge, as the Utilitarian philosophy decrees that the pleasure and pain experienced by all individuals, including animals, has equal worth and must be considered when determining the net benefit of an actions consequences. The most drastic and prevalent of examples that one could provide to illustrate this contradiction would be the practice of using animals to provide food. It cannot be argued that it is in the best interest of a cow, a chicken, or another animal to be slaughtered to serve the dietary needs of mankind. Accordingly, Utilitarian reasoning suggests, in direct opposition to the intuition of humanity, that it is morally impermissible to kill the animals. While a Utilitarian philosopher might provide the counter-argument that such is natural order of the world that there exist a hierarchical food tree. Further they would insist that the greater good is that humans be nourished and provided for by the meat, for our pleasure is superior in quality to that of the beast. This reasoning, however, is flawed in two ways. Initially, the method by which meat finds its way to grocery stores for our purchase and eventual consumption is not one governed by the ways of nature, but rather is one engineered for efficiency by humans. Animals are bread forcibly, then nourished with specific intent of managing fat content, meat flavor, and healthiness, each of which discounts the Utilitarian claim that nature makes our carnivorous methods ethically permissible. Secondly, and perhaps more fundamentally, such a claim is in direct contradiction to the Utilitarian tenet that each individual has equal value regardless of identity or stature. Because humans could be sufficiently nourished without the killing of animals, it cannot be argued that the consequence of causing death to an animal is equivalent or less substantial than that of feeding a man. Conversely, there exist equally as many challenges to raise had the ethicist taken the alternate position that animals have equal value and accordingly that their pleasure is impermissibly infringed upon when they are killed for human interest. Arguments could be presented for a bevy of actions taken on a daily basis by society as a whole. One might address the fact that using animal testing for the advancement of medicine has benefits that outweigh the pains. Similarly, while the development of land effectively kills the previously animal inhabitants, it is an accepted result that society has displayed it is willing to disregard. In each of these cases, the majority of society condones such behavior, as evidenced by their existence as common public practice. While it is undeniable that opposition to each behavior does exist, the magnitude of this resistance is far outweighed by those in finding the long term benefits worthy of the negative consequences. In the end, it grows apparent that while it may be valuable to consider the interests of animals when calculating the net benefit of a given action, neither their pleasure nor their pain should be equated to ours. Such a principle has been introduced through the ethical thought experiment The Dilemma of the Swine. Resultantly, human existence constitutes higher pleasure that does that of an animal and we are often better served by making such a distinction through intuitive analysis rather than applying Hedonistic Calculus. The fact that Utilitarianism can be forced into contradictions regardless of the stance they choose makes the inclusion of animals under their ethical umbrella a significant problem.

Morality and Responsibility - Moral Development in Mary Shelleys Frank

Moral Development in Shelley's Frankenstein   Ã‚   Mary Shelley's Frankenstein is a commentary on the natural disposition of man. By personifying her vision of a natural everyman character in the form of Victor Frankenstein's creation, The Creature, Shelley explores the natural state as well as the moral development of man, and develops conclusions regarding both. But before Shelley could create her commentary on man's natural dispositions, she was in need of a character to represent her "natural everyman." The character she needed had to possess the same qualities as that of a man in his most natural state. The most common character to represent man in his most natural state is that of a newborn. A newborn is, of course, a new human being in every respect, and a newborn has no past experiences that would taint his role as a natural everyman. However, a newborn is subject to the elements of the outside world without the ability to freely interact with those elements. A newborn cannot defend itself from alien environments that bring in new ideas, new friends, new enemies, and new challenges. Shelley's character must be able to always act upon his own free will (or be "freely" influenced by deterministic processes, depending on one's school or thought). However, a newborn is not able to accomplish this; there is too much ambiguity in what determines and develops a newborn's state of mind. Shelley needed something "better" than a newborn. Victor Frankenstein's creation is the answer to his dilemma. The Creature does not possess any of the shortcomings discussed above. He is brought into this world as a fully mobile human, able to act, as he chooses, not dependant upon other human beings to survive. In The Creature, Shelley ... ....
