CHEMISTRY AND THE ENVIRONMENT CHM 1000 spring 2012 LABORATORY REPORT # 2 DISTILLATION OF WINE Presented by: FEBRUARY 18 2012 Introduction: Distillation is a widely used method for separating mixtures based on differences in the conditions required to change the phase of components of the mixture. To separate a mixture of liquids, the liquid can be heated to force components, which have different boiling points, into the gas phase. The gas is then condensed back into liquid form and collected. Repeating the process on the collected liquid to improve the purity of the product is called double distillation. Our experiment consists of distilling wine and record the alcoholic content which is called brandy.
Experiment 5: Titration for Acetic Acid in Vinegar Name: Lab Partners: None Date of Experiment: March 25th, 2013 Location: My House Course Number: Chem 112 Abstract: In this experiment the objectives were develop familiarity with the concepts and techniques of titration and to determine the concentration of an acetic acid solution in vinegar. Experiment and Observation: Data Table 1: Quantity of NaOH needed to Neutralize 5 mL of Acetic AcidBrand of Vinegar Used: Heinz White Distilled VinegarLabel Notes: ______________________ | | Initial NaOH reading(Interpolate to 0.1 mL) | Final NaOH reading(Interpolate to 0.1 mL) | Volume of NaOH used | Trial 1 | 9.5 | 1.3 | 8.2 | Trial 2 | 9.7 | 1.4 | 8.3 | Trial 3 | 9.6 | 1.4 | 8.2 | Average volume of NaOH used: | 8.2 | Calculations and Errors: Errors: Calculations: A. Calculate the average number of mL of NaOH used for the 3 trials and record. B. Calculate the Normality of the vinegar using the previously given equation.
We were given unknown 4, and based on our unknown given our sense observation, besides tastes of course; we concluded that it was high in sugar. We then decided to start with the sugar test first. Materials: For all tests Tubes-3for each group Biuret Reagent Benedicts Reagent Albumin Reagent Iodine Heating element DI water Key: Test for Sugars Chemical
This means that your body is continuously working to digest high fructose corn syrup if the body consumes processed foods or drink soda on a regular basis. This could cause the body to be obese over a period of time ("Three"). After eating fructose, 100 percent of the metabolic burden rests on your liver—ONLY your liver can break it down. This is much different than consuming glucose, in which your liver has to break down only 20 percent, and the remaining 80 percent is immediately metabolized and used by the rest of the cells in the body. Fructose is converted into fat that gets stored in your liver and other tissues as body fat.
In the United States, there was a sort of “temperance crusade” per say happening at the time. Alcoholism was a serious problem in antebellum America, affecting almost every family. Wives of alcoholic husbands were especially involved in this movement. They were often abused by their drunken spouse and money meant for the entire household was often spent on booze. Document H expresses the views on how alcohol substance abuse can be detrimental to a person.
However, Joshua Project Statistics show that 5% or less are professing Christians, and evangelicals are between 0.01% and 2% or less professing Christians.30 Challenges Islam has been deeply entrenched in the minds of virtually all the Hausa people since the 19th century and as a result, “Muslim beliefs as well as social pressures and persecution make it difficult for a Hausa person to leave Islam. The current political polarization between Muslims and Christians in Nigeria also make it difficult to accept Christ.”31 Operation World also report that “There is considerable opposition and trials in the three northern regions, often including bloody violent attacks.”32 As a result of this tension in the Hausa states, it is very challenging to preach the gospel and even profess faith in Christ. Further, the illiteracy rate among the Hausa people also pose a major challenge in communicating the gospel to them; only about 10% of the Hausa population are
Unit 6 Project: Nationwide Synthetic Drug Ban Alaina DAmbrosia Kaplan University CM220-12 Professor Millard April 10, 2012 Spice, K2, bath salts, or incense are all names of dangerous drugs that are being distributed all over the United States. These are all very dangerous synthetic drugs that have been lurking in the shelves of our gas stations, convenient stores and all over the internet. Synthetic drugs are being distributed all over my neighborhood to many children and young adults. There have been many cases of teens who suffered bad side effects, which led to injury and hospital visits. Cleveland, OH has been exposed to a variety of dangerous synthetic drugs that are currently legal.
Many experts will also tell you second hand smoking is more dangerous than first hand, because of the unfiltered smoke containing 50 more cancerous substances than filtered cigarette smoke. The individuals affected by second hand smoke are the most tragic. These people reap the consequences of a dangerous habit they made no decision to partake
Murders by firearm rates are 17.5 times higher than in twenty-two other populous high-income nations combined. The United States is one of the most violent nations in the world. Because of this, suicide rates are very high, and costs are very high. Nearly as many citizens are killed each month, as were killed in the first seven years of the Iraq war. The suicide rate of children between the ages of five and fourteen is eleven times higher than that of twenty-five other countries.
Drug Abuse today affects many people in many places; it tears apart families, countries and even leading to war. It is a major problem within our society, affecting even the most innocent of people. Marijuana alone creates economic and moral issues within the United States. Just one example: over 100 million people above the age of 12 admitted to using marijuana alone at least once in their life that was 40.01 percent of the surveyed people. If such a large percentage of people have used illegal drugs it causes the need for two questions: How many of these people go to prison per year?
