November 30‚ 2012 Soda Pop More and more young people are experiencing hypertension and childhood obesity‚ and because of which are seemingly becoming more prone to various diseases (Should Government Tax Sugary Drinks?). Many take a stand on the issue‚ as New York for example no longer allows the use of trans fats in their restaurants. Still the cost of unhealthy food has remained nearly the same‚ while the cost of a high yield diet has soared beyond that of the rate of inflation (Should Government

Acid-Base Titration Pre-Lab Discussion In the chemistry laboratory‚ it is sometimes necessary to experimentally determine the concentration of an acid solution or a base solution. A procedure for making this kind of determination is called an acid-base titration. In this procedure‚ a solution of known concentration‚ called the standard solution‚ is used to neutralize a precisely measured volume of the solution of unknown concentration to which one or two drops of an appropriate acid-base

Soda Ban Teenagers seem to crave sugary drinks‚ and the growing intake of sugar by young people has kept the Food Ministry on edge. The average daily consumption of sugar by teenagers was higher‚ at 69.6 grams (2.4 ounces)‚ than that of any other age group‚ according to the results of a survey released. Soft drinks were said to be the biggest contributor to that sugar intake. New York City had planned to implement their ban on large sugary drinks such as soda but the ban was rejected because restaurants

Evaluate the statistical analysis packages available for quantitative research. Which statistical analysis packages would be most beneficial for the examination of quantitative data within your study? The four most common statistical packages that nurses use for research are Statistical packages for the Social Sciences (SPSS)‚ Microsoft Excel‚ XLSTAT‚ STATA and SAS (CourseConnect‚ 2016). For my research study‚ I would use the SPSS package because it is easy to use‚ can take data from almost any

take the pennies out of the cups for a few minutes to fully view them. Make sure you write notes and answer several questions about your experiment. Is one type of soda visibly reducing the amount of tarnish present on the penny? Do the lighter sodas take the tarnish off the pennies faster than the darker sodas or do the darker sodas take the tarnish off the pennies faster than the lighter

Jazeya Kalis English 2121‚ Sect. 03 Mr. Carr April 17‚ 2013 Coal Ash Pollution Coal ash pollution is a huge issue that has been looked at many of times in the US. The disposal of coal ash has become the bigger issue here. Coal ash is the toxic by product of burning coal‚ and it’s the second largest industrial waste stream in the US‚ with trash being number one. Millions of tons of coal ash are stored in unsafe dumps that can leach heavy metals‚ arsenic‚ lead‚ selenium‚ and hexavalent chromium

Acid-Base Titrations A Titration of Potassium Hydroxide Phthalate and Sodium Hydroxide Hanna Piper Department of Chemistry‚ SUNY College at Brockport‚ Brockport‚ NY 14420 Chemistry 205.06 Abstract Titrations are used to find the molarity of an unknown solution. A titration begins with an analyte and titrant being used to measure the unknown molarity of the analyte. In the following experiment‚ sodium hydroxide was used as the titrant and potassium hydroxide phthalate was used as the

This will lead us to the “Standardization” a process where a solution’s concentration is determined accurately by titrating against the primary standard. Most importantly this experiment will enable
