Chapter 4: Limiting Liberalism or Generous Germany? If we now have to start apologizing for showing a friendly face in response to emergency situations‚ then that’s not my country. - Angela Merkel. To repent for WWII floods of Syrians‚ Afghans and Iraqis have entered Germany‚ and there “…suddenly become an image of openness‚ generosity and solidarity.” (Godin‚ 2015). Following on from racist violence against Turks in the 1980s and early 1990s‚ there was the rise of the far-right anti-immigrant

Determining the Limiting Reactant and Percent Yield in a Precipitation Reaction Objectives: Observe the reaction between solutions of sodium carbonate and calcium chloride. Determine which of the reactants is the limiting reactant and which is the excess reactant. Determine the theoretical mass of precipitate that should form. Compare the actual mass with the theoretical mass of precipitate and calculate the percent yield. Materials: Balance 0.70 M sodium carbonate solution‚ Na2CO3(aq)

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Experiment 3: Enthalpy of Various Reactions Introduction A coffee cup calorimeter is an apparatus that is used to measure the quantity of thermal energy gained or lost in a chemical reaction. This experiment utilizes this apparatus‚ which is made from two styrofoam cups with plastic lids and a thermometer‚ to measure changes in thermal energy of various reactions. When using this type of apparatus‚ it is assumed that no heat is transferred between the calorimeter and the surroundings‚ and that

This ensures variety of soil to ensure that all the site is safe‚ not just a small area where you would have taken your first sample from. I will return to the lab with the samples of soil I have extracted from the site. Here I will make a solution from the samples in order to carry out the identification tests.

Acid Base Titration Purpose: The purpose is to calculate the molarity of a NaOH solution by titrating the base with 5mL of standard HCl solution in each trial. By adding the base with unknown molarity to the acid with 0.10M the molarity of NaOH can be calculated. The base‚ NaOH‚ helps bring the pH of the acid‚ HCl‚ closer to seven‚ which neutralizes it. When using the buret the amount of NaOH used is able to be determined. Then by writing a balanced chemical equation and using the titration

Our inspiration for this experiment came from a lecture in class about the Los Angeles council agreeing that there should be a law limiting homeless people’s belongings to what can fit in a trash bin. This would force the homeless people to throw away large portions of their belongings to benefit the city from not having “trash” on the streets. According to the L.A. times‚ the legislation California believes that this law will “limit storage on sidewalks‚ parkways‚ and alleys citywide to what homeless

Ever since the competition between the Soviet Union and U.S to occupy space‚ the United States has been on a consistent drive to discover more and more of outer space. Although there are minor independent companies that contribute to space exploration‚ the U.S government

Limiting the Standards of Standardized Testing The Virginia Standards of Learning exams were introduced to public schools in1997. The testing begins in the third grade and continues through high school. Before 2014‚ students were required to take twenty-two state mandated Standards of Learning tests; that has since been reduced to seventeen. High school students must pass six Standards of Learning tests to earn a diploma. I believe students are being over tested and these standardized tests are

Then titrate ¼ of the estimated amount number of mL of NaOH needed to react with the sulphate solution. Then add 5 mL at a time NaOH until Cu(OH)2 precipitate does not form. Record the correct number off mL which forms to NaOH solution. Fold the filter paper and stick inside the funnel‚ and pour the solution of copper
