The Worst Print Media Design - Essay Example According to the studies conducted by Palshaw (1986), these companies’ advertisers are trying to reach out to their potential customers through the use of these media. Television advertising, being the most expensive way of promoting products or services, directly approaches the public. However, advertising through television requires ample budget because these TV commercials should be enticing enough in the eyes of the public. TV commercials should be interesting enough, something that would make their imaginative minds work. Moreover, TV commercials should possess qualities that would hit the companies’ goals; thus, making it very specific (Leebron, 1997). Palshaw (1986) added that with the use of radio advertising, the commercial should be better inclined with either a TV or print media so that it could, in a way, better affect the public. Radio advertising also requires a lot of effort on the part of the companies’ advertisers. Print advertising, on the other hand, can also reach out to the public and directly influence its target market only if the print ad itself is evoking enough. Palshaw (1986) concluded that the best way to promote products or services is through the use of combined or mixed media. For example, a company could promote its products or services using the media cited above. Meaning they can take advantage of TV commercials, simultaneously supported by radio commercials, in addition with print advertising. With this method, the companies can take advantage of every media that reaches out to public market through various waves. And since each of these media have their own advantages and disadvantages, by usin g mixed media, these media compromise each other. In addition, with the use of mixed media advertising, the company can pinpoint exactly which of the advertising methods do most of its integral purpose. Another media that companies could use is, by far, more effective than TV advertising. It is

Chemistry Practice - Bonding energy kinetics - Lab Report Example The bond is covalent in nature. There is a sharing of electrons between these two atoms, giving rise to a covalent bond. The electronegativity value of H is 2.1 while that of O is 3.5 (Brown, LeMay and Bursten, 1991). There will hence be a distortion of the electron cloud, thus causing the molecule to be polar. The bonding between oxygen and hydrogen is polar covalent in nature. Polar molecules are attracted to a charged rod. In these molecules, the centres of positive and negative charges do not cancel each other out, giving rise to permanent dipoles. When a positive rod is used, the negative end of the dipoles are attracted towards the rod while the positive end of the dipoles are attracted to a negative rod. 3. Using the 'electron pair repulsion theory', state and explain the shape of the following compounds and in each case sketcha diagram to show the arrangemant of the atoms in space, labelling the bond angles. In AlCl3, the three outer electrons of the aluminium atom are bonded to the outer electrons of three chlorine atoms. Since there are no lone pair of electrons, the structure will not be distorted. According to the electron pair replusion theory, the three bonded pairs repel each other as far apart as possible. AlCl3 will hence be trigonal planar in shape with a bond angle of 120 (Brown, LeMay and Bursten, 1991). (b) SiH4 In SiH4, the four outer electrons of the silicon atom are bonded to the outer electrons of four hydrogen atoms. There are no lone pair of electrons. According to the electron pair replusion theory, the four bonded pairs repel each other as far apart as possible. SiH4 will hence be tetrahedral in shape with a bond angle of 109.5. (c) PCl5 In PCl5, the five outer electrons of the phosphorus atom are bonded to the outer electrons of five chlorine atoms. There are no lone pair of electrons. According to the electron pair replusion theory, the five bonded pairs repel each other as far apart as possible. The shape of PCl5 will be trigonal bipyramid, with bond angles of 120 and 90. 12 marks 4. Enthalpy changes for the reactions of carbon and aluminium with oxygen are given in the following equations, where all substances are in their standard states. C(s) + O2(g) CO2(g) H = -394 kJ mol -1 4Al(s) + 3O2(g) 2Al2O3(g) H = -3352 kJ mol -1 (a) What is the value for the standard enthalpy of combustion of carbon The standard
