Dative Bond Definition (Coordinate Bond)

A covalent bond forms when two atoms share electrons. The electron pair is attracted to both atomic nuclei, holding them together to form a bond. In a typical covalent bond, each atom supplies an electron to form the bond. A dative bond is a covalent bond between two atoms where one of the atoms provides both electrons that form the bond. A dative bond is also known as a dipolar bond or coordinate bond. In a diagram, a dative bond is indicated by drawing an arrow pointing from the atom that donates the lone electron pair toward the atom that accepts the pair. The arrow replaces the usual line that indicates a chemical bond. Key Takeaways: Dative Bond A dative bond is a 2-center, 2-electron covalent bond in which both electrons come from the same atom.A dative bond is also called a coordinate covalent bond or a coordinate bond.Dative bonds are common when metal ions bind to ligands. Dative Bond Example Dative bonds are commonly seen in reactions involving hydrogen (H) atoms. For example, when hydrogen chloride dissolves in water to make hydrochloric acid, a dative bond is found in the hydronium ion: H2O HCl → H3O Cl- The hydrogen nucleus is transferred to the water molecule to form hydronium, so it does not contribute any electrons to the bond. Once the bond is formed, there is no difference between a dative bond and an ordinary covalent bond. Source Greenwood, Norman N.; Earnshaw, Alan. Chemistry of the Elements (2nd ed.).

Adam Smith and the Reasoning Behind his Thoughts on the...

The power of reasoning allows limitless inquiry into the nature of all things. Adam Smith an â€Å"enlightened† thinker utilizes reasoning to examine the wealth of nations, but in acting on this reasoning is he forcing his own sentiments into his argument, or is the reasoning creating the sentiments? Smith offers an exposition for his vision of a laissez faire economy, that is, capitalism in the modern sense. In a wider scope, Smiths account reveals his views on the nature of the human condition, and not a single theme is surveyed without an observation being made upon human tendencies and decisions. Arguably, these observations are shaped by his own sentiments. Smith makes about three claims about human nature. Primarily, Smith assumes†¦show more content†¦More so Smith is suggesting that human reason is the catalyst for trade. The ability to reason is the singular factor that allows for the development of a free market system. The divisions of labor must be controlled by a rational actor; such notions are arguably the mechanisms’ of â€Å"self love† acts as an actor which drives the capitalist machinery. The example of the pin maker illustrates this point. Lastly, Smith instills â€Å"a certain propensity in human nature; the propensity to truck, barter, and exchange one thing for another.† This, he suggests, may simply be an extension of reason. It is this final, and most specific, penchant of human nature that ensures a vague sense of self interest, coupled with reason and speech; produce a very particular kind of capitalist economic system, which he describes in the rest of the book. In speaking about labor, Smith characterizes it in a negative light. He observes the division of labor as positive to production and competition, but in the social sense sees it as a dummying of the masses. â€Å"The man whose whole life is spent in performing a few simple operations†¦ has no oc casion to exert his understanding, or to exercise his invention in finding out expedients for removing difficulties which never occur.

Policy Monitoring and Enforcement Strategy Essay Example

Policy Monitoring and Enforcement Strategy Essay The possibility of abuse of companys resources is a real risk that can lead to regulatory noncompliance Monsoons, 2011). To ensure the companys profitability and survivability would need strict enforcement of security policies. The two most monitoring and enforcement policies I would be most concerned about is, Access Control, and virus protection. The monitoring regulations I would rely on for this activity are audit trails provided by logs, and ISO 27001/27002 formerly ISO 17799:2005), ITIL and NIST SP-800 53 Recommended security controls for Federal Information Systems standards. Logs are a great monitoring tool that provides a record of events. As such, I need every occurrence to be logged, tracked and reported on. For each entry, I want to know what occurred, when it occurred, and who or what cause it. Monitoring compliance would allow me to: (1) Detect and correct violations (2) Provide evidence to support enforcement actions (3) Evaluate program progress by establishing implicate status (4) Provide case studies for staff training (The SANS Institute, 2012). At each location I would nominate SIS enforcement officers who will be held responsible for monitoring and enforcement strategies to ensure that employees act in according with acceptable use policies (Pups), set forth by management to ensure the organization assets are protected.

It facilitates seamless analysis, as when an alert that deeds more investigation has been identified, it makes a decision on how to handle the situation. Sigil uses a backbend database for most of its data, which allows users to perform SQL queries against several different types of security events (The SANS Institute, 2012). For access control, I would use The least privilege principle whereby employees will be granted only enough privilege to accomplish assigned tasks and no more. I would also use Separation of duties principle whereby employees responsibilities and privileges would be divided to prevent a person or mall group of collaborating people from inappropriately controlling multiple key aspects of a process and causing harm or loss Monsoons, 2011). DoD business transactions rely on EPIC ADS to prevent card data being stolen. As such, we need the early detection of virus protection to detect mallard, and prevent a breach of the system from occurring. Regular patch management updates will be a mandatory requirement In all locations. Policy enforcement can be accomplished through automated or manual controls Monsoons, 2011). Some of the controls I would utilize are: (a) Authentication methods b) Authorization methods (c) Data encryption (d) Data segmentation (e) Network segmentation. According to Johnson (201 1), automated policy management tools take security policies and Implement them as configuring updates. Once the device Is configured, the automated control enforces the policy. The enforcement can be enforce is a preventative control, which would have employees changing their passwords every 30 days. To ensure monitoring and enforcement policies are adhered to, a security awareness policy would be implemented to raise awareness of these regulations.

It seems as though the redo titration is a more accurate and reliable method for determining the percent of iron in an unknown sample. It seemed as though analyzing the sample would be more accurate using the spectrophotometer but upon experimentation and statistical comparisons of the two methods it is clear the redo titration would be a better choice for better and more accurate data.

Marketing Project Example

Marketing Project Example Marketing Project Example The marketing project example is the type of creative work aimed to successfully advertise products or services. Â  In the modern world, the trend of preferring local producers of all the possible goods is becoming more popular every year. People tend to believe that a local producer would have the best quality of grocery or other goods just because they are produced in the area around consumers. That is why, the marketing project example is going to describe the campaign designed for the local company. To start the local company, an entrepreneur should do a huge amount of work. An essential step is to conduct a marketing campaign about the product of the future company to find out the market size, possible revenue, and volume of sales. The company, which would be the scope of the research is the new grocery store with one hundred percent natural, GMO and pesticides free products. The first step of each marketing campaign is setting the goal of it. It sounds slightly easy but each purpose of sales or marketing should have different campaigns, which use different tools and methods to operate it. In the case of launching a new local grocery brand, the marketing campaign should answer the questions about intended volume of sales, market size, and expectations about profit. The deadline for this marketing project completion is three months, which is enough to conduct an extensive research and analyze the obtained results. The success of the marketing project and its level of confidence mainly depends on the methods of marketing research, which were to create this project. It means that methodology should be chosen very carefully. In the case of a new grocery store, it was decided to choose an effective mix of methods, which would provide both scientific and ‘field’ data. Firstly, focus-group method would be applied. It would help to get the scientific social information about the intended consumers of this area and to assess the prospects of the new store. The second method would be the observation of the real grocery events during two months. It would provide the marketing specialists with the most relevant information, which is gathered ‘on the field’. The reason of choosing those two methods is because they support each other. One is very credible with small groups, but still is a sociological one, which means that it could have irrelevant data because of the focus-group size. Another method is not so exact, but it provides a general idea about the market and prospects of the new brand. After two months, the research specialists could start working with gathered information to organize it into the proper marketing project summary. The obtained information was gathered by fifty focus groups; each consisted of fifteen people with a different demographic background. Furthermore, the analysis of eleven events from the intended market, for instance, weekend grocery markets or thematic events of this industry have also given some relevant info. The marketing specialists made an excellent job to analyze the obtained data, using the last version of STATISTICS software. The marketing project is credible and relevant, which is shown by the 95 percent confidence of the obtained data. References Hall, R. (2009). Brilliant marketing.

Economic of race and gender Assignment Example | Topics and Well Written Essays - 750 words

Economic of race and gender - Assignment Example These films could be brutal but sometimes, reality is worst than we would like it to be. The stories are just examples of what really happens in this world, whites discriminating Blacks or Asians and men acting like gods over women. What could be alarming is to know that there are also other skin colors discriminating the whites and more shockingly, women discriminating men. The films may have not shown the latter but in reality, things happen and it is not a news to break because there have been news of domestic violence also where the men are the victims. It is sad to realize that we can not escape these realities and they could happen to any of us. It is then very helpful to be educated about the issues on race and gender discrimination. Taking this class has opened my eyes and my understanding of the existence of such acts, now I know the rights of a person one needs to fight for, as well as what way of thinking one should have so as not to involve ones self in such actions. I believe that if I consider not discriminating, there would be one less racist in this world and no matter how minute its effect could be; still I could impact the world I am moving in. Diverse social positions can lay the foundations of a person’s political and economic access. For instance, a poor person can be deprived of education in his early years because he has to work in order to survive. Eventually, he will have minimal probabilities of ever going to school to get a better job in the future. Politically, he would have limited access to the rights of a regular paying worker if he ends up with menial jobs which do not give him the benefits of government employed workers. Loss of job pushes a person to self-employment particularly getting in to business because it gives advantages like being the boss of oneself, the opportunity for success and the convenience
