Stage 2 Chemistry Investigation Folio: Practical – Galvanic Cell Name: YY Names of Partner: ZZ Part A Investigation Design Proposal: Purpose of Experiment: To determine the effect of concentration of reactants on the current produced by a galvanic cell. Hypothesis: The greater the concentration of solution in the two half cells reacting with the two metals to produce current‚ the greater the flow of current will be produced from the galvanic cell. Independent Variable: Concentration

Personal Statement The decision to study a Masters degree in Chemistry at university stemmed from my studies of chemistry at GCSE. As someone who is naturally inquisitive‚ I have found that chemistry is a subject which seems to explain the world around me. This interest in chemistry has been encouraged by frequent visits to the Heart Hospital in London from a young age. Through this‚ I have developed a particular interest in the workings of medical equipment‚ especially learning about the theory

Alchemy vs. chemistry Some people think that chemistry is just about mixing things up and experimenting in test tubes and explosions. Actually chemistry studies everything around us and how they change‚ for example it tells what your body is made out of. We study chemistry in biology‚ geology‚ engineering‚ and even physics. Chemistry is the science of matter‚ and how it changes and its chemical reactions‚ it’s also called as the central science ( the main one) because it connects physics with other

Ahmed Fun Filled Hands On Science 17 January 2013 Demonstrations in Chemistry Class Chemistry is a class that a lot of college student are afraid of‚ and when I think of chemistry‚ complex equations that don’t benefit come to my mind. The reason is that all I got out of chemistry is those unbeneficial equations‚ for me at least. Also‚ I learned that H2O is water. With all those negative statements‚ I still believe that chemistry is a very important subject to understand the magic of this life and

After awhile those classes seemed to mesh together‚ the difficulty of the class wasn’t there anymore‚ I wasn’t stimulated with new knowledge. It was pure monotony of the state regulated standard that pushed me to a higher and more distinct class. AP Chemistry was the catalyst for my intellectual development and my new found quest for knowledge. From the first day‚ I collided with my syllabus‚ it was frightening yet exciting at the same time because it was the academic challenge I was looking for. Going
