In conclusion‚ the concentrations and absorbance of the Kool-Aid solution were found. The purpose of the experiment was to develop a deeper understanding of the effect that concentration has on the absorbance of light–which the objective was met. To add‚ another goal of the experiment was to determine the unknown solution’s concentration using the absorbance data recorded. This was concluded to be 0.25 M–most similar to Solution #1. Concentration‚ measured in molarity (M)‚ can be calculated using

Concentration Camps During the Holocaust Bergen-Belsen Concentration Camp was located in north central Germany near Hanover. The camp is named after the nearby villages of Bergen and Belsen. It was created in 1939 during World War II. In 1940‚ a prisoner of war camp was constructed. At the camp‚ the conditions were harsh and extreme; abuse‚ disease‚ and starvation was very common throughout. One woman‚ Alice Lok Cahana‚ who was deported from Auschwitz to Bergen-Belsen in 1944‚ described the camp

Biochemistry of Proteins; Isolation of Ovalbumin and Enumeration of thiol groups Abstract Thiol groups are important to protein folding and forming disulphide bonds that are essential to protein structure. Determining the number of thiol groups in a protein is important in determining the tertiary structure of the protein. The ovalbumin is the experiment was purified from egg white using centrifugation and ammonium sulphate precipitation and then the thiol groups identified using DTNB and spectroscopy

Effects of Molasses Concentration on Yeast Fermentation The purpose of this lab was to determine how yeast cells are affected by the concentration of a food source‚ and for our purposes‚ the food sources were corn syrup and molasses. Our hypothesis was that the yeast cells would ferment the most when there was a higher concentration of molasses/corn syrup. In order to test this‚ we created 10 test tubes with decreasing concentrations of molasses/corn syrup using a serial dilution. Each test

four food apple sauce‚ carrot juice‚ cracker juice‚ and turkey juice contain protein‚ starch‚ or sugar. Between these four foods two are positive for sugar which are apple sauce and carrot juice. Sugar is an organic molecule of carbohydrate and so is starch. The starch was positive in two of the foods which are cracker juice and carrot juice. Protein is its own organic molecule and only one food tested positive for protein and it is the turkey juice. Introduction The “Food Lab” was used to answer

Abstract: The purpose of this experiment was to determine the concentration of an unknown amount of copper sulfate using the spectronic 20. Four solutions of different concentrations of H₂O and CuSO₄ were put into the spectronic 20 to observe their absorption of light. Then‚ a graph was created to plot down the measurements. Using the calibration curve of the graph‚ the concentration of the unknown substance was found out to be .12M. Background/Introduction: Beer’s law (which states that

Concentration vs Rate of reaction Brandon Introduction A reaction rate is the speed at which a chemical reaction will occur. Heat‚ concentration of a chemical‚ Surface area or a catalyst‚ will affect the rate of reaction. The concentration of a chemical will speed up of the reaction because the reactant particles have become more crowded therefore increasing the chance of productive collisions. In this practical the chemicals will be Sodium thiosulphate and Hydrochloric acid which will produce

The effect of salt concentration on grass growth Abstract Our aim was to test the effect of different salinities on the growth of plants which what we did was measured different amounts of salt dissolved into 2 litres of water‚ watered the plant once with the salt water then for 9 days with pure ware. I found with my investigation that the less the salt‚ the more the growth of the plant. My aim was achieved by measuring the 5 fastest geminating (out of 20) and to measure the differences in growth

Auschwitz concentration camp (German: Konzentrationslager Auschwitz‚ pronounced [kɔntsɛntʁaˈtsi̯oːnsˌlaːɡɐ ˈʔaʊʃvɪts] ( listen)‚ also KZ and KL Auschwitz) was a network of German Nazi concentration camps and extermination camps built and operated by the Third Reich in Polish areas annexed by Nazi Germany during World War II. It consisted of Auschwitz I (the original camp)‚ Auschwitz II–Birkenau (a combination concentration/extermination camp)‚ Auschwitz III–Monowitz (a labor camp to staff an IG Farben

Politicians declared that we would never let concentration camps like that of Hitler’s in Nazi happen again. However‚ North Korea has concentration camps in the modern era. But North Korean concentration camps have lasted longer than Nazi concentration camps. No country takes action or helps North Korean political prisoners. North Korea commits crimes against humanity. There are 150‚000 to 200‚000 North Koreans in concentration camps. These Koreans are in death camps for minor crimes and most of
