School: South Creek middle school Title of Essay: Never give up Intro- Wow this has been an amazing year‚ especially being a part of the AVID family. My experience with AVID has been one of the most memorable yet. Before I was in AVID I was a trouble maker‚ but I was good at school but I could do better. Organization- I was horrible being organized; I could never figure out what homework I had that night or were my notes were. Hearing about AVID- at the end of my 7th grade year I was invited

neutralization equivalent for the carboxylic acid can be obtained from the base. It is most important that you accurately weigh your sample of acid and titrate to a phenolphthalein (colorless to pink color) end point using an accurately known dilute solution of sodium hydroxide (0.1000 M). If your unknown is soluble in a greater than 50% ethanol/water mixture‚ then use bromothymol blue as the indicator to give a yellow to blue color change. Using an analytical balance‚ accurately weigh out approximately

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

exchange of heat (or energy): in combustion reactions great deal of heat is released in neutralization reactions and others. Transfer of heat is a major theme of thermodynamics‚ the science of heat exchange (or energy exchange). Q: Why it is important to know the quantity of heat (energy) involved in a chemical reaction? Answer: when chemical reaction takes place the rearrangement of atoms takes place and some bonds have to be broken (energy is needed) and new bonds form (energy is released)

benzene can be hydrogenated‚ the result being a cyclic hexane: | +3H2 | | Under the influence of light‚ chlorine or bromine addition at the benzene’s molecule giving hexachlorocyclohexane: C6H6 + 3Cl2 C6H6Cl6. With ozone‚ the benzene gives a trizonide‚ which by decomposing (with water)‚ passes in glycoxal. These addition reactions prove the following: benzene has a cycle of 6 carbon atoms; there are three double bounds in the cycle. Yet‚ the addition reactions at benzene take place only
