Case Study Example The type of chemical reaction that was taking place in T2 laboratories reaction chambers was an exothermic reaction. An exothermic reaction is a type of chemical reaction where energy is produced during the reaction (Atkins & Paula, 2001). In a typical reaction, for a product to be formed then energy has to be supplied in order to break the bonds of the reactants, however during the formation of products, energy is released. In case of an exothermic reaction, the energy released during the formation of products is higher than the one needed to break the bonds of the reactants. In connection to this, the excess energy is released in form of heat (Atkins & Paula, 2001). In order to show the change in energy as a reaction progress, most chemists prefer using potential energy diagrams. A potential energy diagram has the y-axis representing the potential energy and the x-axis showing the change in potential energy as shown in figure 1 (Atkins & Paula, 2001). Although, just like any other form of reaction, energy is conserved and the excess energy that is not used up is released to the environment in form of kinetic energy, light or heat as shown in figure 3 (Atkins & Paula, 2001). T2 laboratories manufactured {Methylcyclopentadienyl)-manganese(I)tricarbonyl}, a gasoline additive. The chemical reactions used to produce the product were exothermic in nature. Therefore, it is important that the company knows the maximum amount of energy that can be released by the reactants in order to prevent vessels from bursting. It is important that training activities and materials incorporate all aspects of chemical hazards. In addition, all employees especially those in the processing section should be made aware of the consequences of not following the laid down procedures (EPA, 2005). In regards to T2 laboratories, the owners of T2 laboratories were trained on chemistry and chemical engineering. However, it seems they were not trained on chemical reactivity

Results of the Crusades Essay Example | Topics and Well Written Essays - 250 words

Results of the Crusades - Essay Example However, the main motivation behind the crusade of Muslims was the urge to spread their religion all over the world. This Muslim crusade started even before the crusade of Christianity in Europe. For instance, many Muslim clerics, scholars and activists were indulged in the crusade of Islamic group. The Christianity crusade was a failure and it weakened the position of Pope as a religious leader. The crusade degraded the strength of feudal nobility and decreased the power of kings of Europe. The Byzantine Empire was weakened by the fall of Constantinople and many knights got killed in the crusade. However in the crusade, the Chrisitans got advantages from the trade side. Due to crusade Europeans could avail themselves of cloth, spices and fruits from South Asian countries. This aspect was a benefit to both Muslim and Christians. According to the historical records, Islamic and Christian crusade fall on equal stands in regard to their benefit. However Islamic crusade success was very high compared to Christianity crusade because the war worn out empires of Byzantines and Persia was in power vaccum and Islam won these regions with less
