Nuclear Chemistry: The Good vs. the Ugly The definition for nuclear chemistry is the application of chemical techniques to the solution of problems in nuclear physics. This includes the discovery of naturally occurring and synthetic radioactive elements and the results of nuclear fission. There are both pros and cons in nuclear chemistry. People believe that nuclear chemistry is bad for the environment but there are a lot of great things that can come out of this. Things like medical uses‚ food

1. How structurally attractive is the Russian ice cream market? How is it likely to evolve? Analyzing from using five force model we can conclude that the structurally attractiveness of Russian ice cream market is quite low due to several reasons. Firstly‚ the crisis in 1998 had greatly reduced the consumption ability of ice cream market and increased the imported ingredients for producers. Secondly‚ Centralize planning system that is used in Russia caused the Russian managers to have little

Please provide an in depth five forces analysis to illustrate the competitive environment for Russia’s ice cream industry. How is it likely to evolve? The competitive set of the ice cream industry is highly fragmented and very diverse. International brands such as Nestlé have through their size‚ position and also advertising expenses managed to capture market share. The local‚ much smaller producers on the other hand have the majority of the Russian population on their side. In addition their organizational

Chemistry design: Fuel energy lab Research question: What is the energy density of cyclohexane‚ and how does it compare to the energy density of normal hexane? Variables: Independent variable – The independent variable in this experiment will be the type of fuel that will be used. This will be either Hexane or Cyclohexane. Each type will be given to us and labelled so it will be quite simple to control this variable. This cannot be measured using any apparatus so the lab assistant must be entrusted

EXPERIMENT 2: SYNTHESIS OF ORANGE II (2-NAFTHOL ORANGE OBJECTIVE 1. To produce dye based to the coupling of diazonium. 2. To understand the characteristic of dye orange II. INTRODUCTION The first dye was introduced by William Henry Perkin on 1856. It can be produced by the coupling of diazonium sulfanilic acid with nafthol in alkaline solution.. This was the common method used to produce dye nowadays. In this experiment‚ dye produced was the orange II. Azo compound is compound that contain
