recycling of plastics bringing any long-term benefits to the environment? Plastics are one of the most popular building materials of modern human culture‚ but its widespread has brought many problems and caused environmental issues of extraordinary scale. Throughout the years‚ discarded plastics are accumulating as debris in landfills and in natural habitats worldwide. To control this issue‚ governments of many countries have established industrial processes for transforming discarded plastic into useful

Television Television has had a significant influence on the culture of many societies. To what extent would you say that television has positively or negatively affected the cultural development of your society? It is unarguable that television has had a considerable impact and changed the world in which we live. However‚ there is debate whether that change has been for the better or the worse‚ when we consider cultural development. While there are certainly strong feelings on both sides of the

INTRODUCTION For this experiment we studied an oxidation-reduction reaction of magnesium and hydrochloric acid solution. We compared the experimental measured amount of a product and the amount predicted by the theoretical calculation of a balanced equation: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g) PROCEDURE First we obtained a strip of pre-cut magnesium ribbon‚ cleaned it with steel wool to remove any signs of oxidation from the strip (which would alter our results)‚ and then weighed it (individual

An Oxidation-Reduction Scheme Nicolas Gibson Lab Time: Tuesday 11:30 am Abstract: In this experiment‚ the main objective was to synthesize a ketone from borneol via an oxidation reaction and secondly‚ to produce a secondary alcohol from camphor via a reduction reaction. Therefore‚ the hypothesis of this lab is that camphor will be produced in the oxidation reaction and isoborneol will be the product of the reduction reaction because of steric hindrance. For the oxidation step

A thief only comes to steal‚ kill‚ and destroy‚ but I came to give life-life in all its fullness- John 10:10 NCV. Unfortunately‚ in this case this is what the two thiefs were after. Everyone can agree that the men were planning to steal Robin and his companions’ leather pouch filled with money‚ but some believe that Robin should have warn the others about the robbers‚ while others believe Robin should not warn the others about the robbers. Robin should warn the others about the robbers for three

colorless‚ the end point titrations using KMnO4 as the titrant can be taken as the first pink color that appears in the solution (and stays without disappearing). The titration which involves the oxidation of Fe2+ ion to Fe3+ by permanganate ion‚ is carried out in sulfuric acid to prevent air-oxidation of Fe2+ (we can them determine the accurate number of oxygen reacted this way).

Plastics have been around for a long time now. It has been said that even before Alexander Parke’s major pioneering contribution to the development of plastics from cellulose nitrate in the 1850’s‚ plastic like materials have been in use by mankind for centuries. Now life without plastic cannot even be imagined. Almost every piece we use day to day is either a plastic or has plastic components in it. Because plastics can be made into products of different strengths and flexibility we can find plastic

9.1.1 Define oxidation and reduction in terms of electron loss and gain. Oxidation: the loss of electrons Reduction: the gain of electrons 9.1.2 Deduce the oxidation number of an element in a compound. Always determine elements that never change their oxidation number then ensure the charge of whole molecule is right. N.B. Atoms in elemental state have oxidation numbers of 0 9.1.3 State the names of compounds using oxidation numbers. Example of this in iron‚ can be iron(II) or iron(III) 9.1.4 Deduce
