1. A class that I believe was most particularly significant to me is AP Chemistry. Prior to enrolling in the class‚ I was mostly breezing through school without having to put in a considerable amount of time for homework and studying purposes. A few weeks into the course however‚ I had realized that this class was not going to be even close to the ones I have taken before in terms of the rigor and depth of understanding required to succeed. Now that I have finished the course‚ albeit with a B first

and relationships‚ utilizing various poetic techniques to achieve this. Two poems‚ An Absolutely Ordinary Rainbow by Les Murray and In the Park by Gwen Harwood‚ are examples of poems that make use of techniques to give an observation on human behavior and relationships. The two poems differ from each other in subject matter and the way they comment on human behavior. An Absolutely Ordinary Rainbow deals with expression of emotion whereas In The Park provides insight into society’s view of stereotypes

The Titration of a Basic Solution of Unknown Molarity with a Standard Hydrochloric Acid Solution Abstract The aim of the experiment was how to determine the molarity of a solution. My hypothesis was if I have to determine the molarity of a NaOH solution‚ then I would have to use a standard solution of HCl solution because I would need to neutralize each other to determine the concentration of the solution of NaOH. The method that I used for this experiment was titration. Titration helped

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

A Comparative Study On The Combustibility Of Ethanol (C2H5OH) And Hydrogen Peroxide (H2O2) Mixtures As Fuel Chemistry January 31‚ 2013 Revised February 15‚ 2013 Abstract In this experiment‚ the proponents used mixtures with varied proportions of ethanol and hydrogen peroxide to know which would make a more efficient‚ clean‚ and stable combination. Compared to conventional fuels‚ ethanol contains 36% oxygen thus resulting in more complete combustion. This greatly lowers
