The Sequence of Chemical Reactions Drew Selfridge Dave Allen‚ Lab partner Instructor Yang February 11‚ 1997 INTRODUCTION This experiment was to recover the most amount of copper after it is subjected to a sequence of reactions. The copper is originally in solid form‚ but the reactions will turn it into free Cu+2 ions floating in solution. The ions will then be regrouped to form solid copper once again. During this process‚ however‚ some of the Cu+2 ions may be lost. The copper will subjected

Analysis of a Chemical Mixture Using the Ideal Gas Law The objective of this experiment was to determine the composition of the NaNO2 mixture in the net ionic reaction of NO2-(aq) + HSO3NH2(aq) → HSO4-(aq) + H2O(l) + N2(g) in unknown mixture number nine. It was known that NO2-(aq) and HSO3NH2(aq) were in a stoichiometric 1:1 molar ratio. In trial one the percent mass of NaNO2 in the unknown mixture was 59.30%. In trial two‚ the percent mass of NaNO2 was 63.47%. Lastly in trial three

range of consumers. According to the different qualities‚ the prices of wines are quite different. So when the wine sellers buy wines from wine makers‚ it’s important for them to understand the wine quality‚ which is in some degrees affected by some chemical attributes. When wine sellers get the wine samples‚ it makes difference for them to accurately classify or predict the wine quality and this will differentiate their profits. So our goal is to model the wine quality based on physicochemical tests

regulate or research the effects of chemicals on living organisms can cause many health risks to their citizens and the environment. One such instance in history is in the United States of America after World War II‚ where synthetic chemical pesticides used by the government and farmers grow crops. Rachel Carson researched on why these pesticides were unsafe for humans‚ animals and especially nature. Rachel Carson fought to bring global attention to the use of chemicals. As well as launching the awareness
