However, without the exploitation of minerals, the human way of life would be in question and this has made it difficult to change some of the ways in which human beings use resources (Both, 2005, p. 1). For instance, using fossil fuels as a source of heat is an aspect that will probably continue to exist until when this resource will deplete. In comparison to this example, aluminum can be said to be in a fortunate position as it is among the most abundant elements in the planet...

Decomposition of hydrogen peroxide 28/10 Introduction H2O2 decomposes through a redox reaction to form water and oxygen: 2H2O (aq) ------------------> 2H2O(l) + O2(g) This reaction is very slow since H­2O2 is a very stable compound. It can remain stable for several years. To speed up the reaction a catalyst is used. Examples of catalysts that can be used are potassium iodide, catalase (Williams) and iron (III) nitrate. The redox reaction of H­2O2 is an exothermic kind. By measuring how the temperature changes when H­2O2 and a catalyst are mixed, it i...

...Aluminium alloys offered the best choice with Aluminium 2014-T6 taken as the best choice (ASHBY, M. F. 2005). The challenge is the strength and this was solved by adjusting the geometry of the stiffening web in the side opposite to the load bearing region and increasing the number. The mass of the initial bracket from the mass properties section is 94.89 grams. The redesigned model is as shown in figure 8. The mass of the model is 85.4 grams. Figure 7: 3D model of the redesign The reduction in weight= The initial bracket shows the maximum stress exceeds the yield stress when the 1kN force is applied. The redesign needs the yield...

...aluminium foil and a timer. Place a dry and a moist paper at the end of the tray, next to each other. Then place one paper box with their bottom cover removed on top of the dry paper and the other paper box on top of the moist paper. Using the light source illuminate the tray evenly from the stand lamp placed sideways some reasonable distance away from the tray. Place the 15 woodlice at the tray centre and let them walk on the tray for 30 minutes while and start to observe...

China in Metal Industry Introduction: Current records reflect that China’s steel output exceeds 100 million tons in a year on average and the country is now the world’s largest producer of steel (Hu & Ping, n.d., p.1). The present study focuses on the role of China in the metal industry before and after joining the WTO considering the physical market, the price discovery, and security and risk management. Role of China in the Metal Industry: Before and After Joining WTO: With the li...
