In the lab‚ the purpose was to standardize a KMnO4 solution than using it to evaluate how close a H2O2’s concentration was to its labeled concentration. In this lab‚ it was decided to compare the concentration of new Publix brand hydrogen peroxide to an old sample of the same solution. From the data collected in the first part by titrating a solution of FeSO4*7H2O with the KMnO4 solution‚ it was determined that the concentration was .028M MnO4-. This was able to be done because a known amount of

Aurora O’Bryan Prof. Kaufman 11/6/2007 Textual Analysis Knocked Up Intended for the enjoyment of the present-day youth generation‚ the 2007 comedy film Knocked Up deals with more than just comedic issues. Technically introduced as a romantic comedy‚ this film serves more to its comedic orientation. With awkward romance and stoner mannerisms‚ the laughs are plentiful for the intentional audience of Knocked Up. However‚ as the audience is served its fill of laughter‚ issues are presented that rarely

An astronomer has a goal to discover and understand the nature of objects in our universe. Astronomers analyze and interpret the information obtained in order to make accurate models of these objects using instruments that collect‚ record‚ disperse and magnify the light that celestial objects give off. In this laboratory I learned how to measure the altitudes of stars using a quadrant. A quadrant is a quarter of a circle that has been divided into 90 degrees. I also learned how to find the angular

_______________________________________ ABSTRACT The experiment aimed to determine the equilibrium constant Keq of the formation of Fe(SCN)2+ from Fe3+ and SCN- in the equation Fe3+(aq) + SCN-(aq) ⇌ Fe(SCN)2+(aq)‚ through spectrophotometric analysis. Acidified solutions (using 0.1 M HCl) of FeCl3 and KSCN were prepared for the calibration of the UV-Vis spectrophotometer (using standard solutions) and the determination of Keq of the Fe(SCN)2+ formation (solutions with unknown concentrations)

Nick Eigenheer ENGL 1121 January 23‚ 2013 Weihe Moment Analysis My heart sank as we heard about the terrible news. We knew it was bound to happen sooner or later. The longer it took for us to find our names; the harder it became to flip through the pages. We flipped to where our department was located and my heart nearly stopped. The page was more blank than expected. Two names remained on the page that was once filled with dreaded long hours for the upcoming week. There it was‚ my name‚ all

Qualitative Analysis of Cations Short Overview The most common cations have been placed into five groups based upon solubility in aqueous solutions when different reagents are added. The reactions which occur are useful in identifying the presence of these cations in unknown samples. The process of identifying the cations is called qualitative analysis. The purpose of this experiment is to identify which cations are present in unknown solutions. A data sheet was not prepared for this experiment

increased rapidly as time has gone by. In “Growing Up Tethered”‚ Turkle proves that the young generation need to be connected at all times by relying on their phones a lot Turkle mostly describes by pathos to persuade to feel in the certain emotion. For example‚ she says “I’ll pull up my friend…uh‚ my phone. Julia’s language slips tellingly. When Julia thinks about strong feelings‚ he thoughts go to her phone and her friends she mixes together “pulling up” a friend’s name on her phone and “Pulling out”

Purpose: The purpose of this lab was to analyze the trends of the atomic radius (AR) and the first ionization energy (IE) for the first 36 elements of the periodic table. Procedure: A piece of graph paper was given out by the teacher. A periodic table that has the atomic number‚ atomic radius (AR)‚ and first ionization energy (IE) was given out by the teacher. A sheet of paper was taken out to record the elements‚ atomic number‚ atomic radius (AR)‚ and the first ionization energy (IE). To record

The film “Fed Up”‚ produced by Katie Couric and Laurie David‚ was an interesting and informative film about the dangers of sugar consumption and its contribution to obesity. The strengths of the film were that they gave examples of two major changes that the food industry made to try and save themselves instead of putting the people’s best interest first. Therefore‚ the American Academy of Family Physicians teamed up with coca cola to say that soft drinks had nothing to do with obesity‚ when science
