Topic: Silver is an ancient mineral that dates back since prehistoric times. One thing that makes silver so special is that it was one of the first five metals that we started to use. Silver is found in almost every electronic device there is‚ and as time progresses the usage of it increases‚ unfortunately the amount there is left decreases. How is it created or source of the mineral? (5) Silver is not originated from Earth‚ as it happens it came from space. Many elements were formed in the big

Concentration of a Solution: Beer’s Law The objective of this experiment is to determine the concentration of an unknown copper sulfate solution. You will be using the Colorimeter. In this device‚ red light from the LED light source will pass through the solution and strike a photocell. A higher concentration of the coloured solution absorbs more light (and transmits less) than a solution of lower concentration. The Colorimeter monitors the light received by the photocell as either an absorbance

completely unaware of the horrific events about to unfold that would overshadow their city still today. The citizens of Dachau were oblivious that their city was going to become the origin of concentration camps and of the Holocaust‚ the mass murder committed by the Nazi s in World War II. Dachau Concentration Camp‚ which would soon be placed on the edge of their community‚ would serve as a model for all Nazi extermination camps. This perfect prototype of a Nazi killing machine has come to represent

are Concentration camps? All Jews were starting to get arrested because Hitler didn’t like them. The Jew’s population was going down every day because Hitler was arresting them and killing them. The first Concentration camp opened in Germany in 1933. The police and local civilian authorities organized numerous detention camps. The Nazi controlled Europe between 1938 and 1945. What is a Concentration camp? What is the purpose of a Concentration camp? What is it like to live in a Concentration camp

I am going to investigate osmosis when potato is placed in different concentrations of sucrose. I am aiming to witness osmosis in 5 different concentrations of sucrose. I will use 5 varying concentrations so that I have a wider spread to compare the results‚ and check that I don’t have any anomalies Prediction Osmosis is the process of diffusion of water molecules from a weaker solution into a stronger solution‚ through a semi permeable membrane. The tiny pores in the membrane

Metal Works Case study Project Summary- Metal-Works is a manufacturer of steel products such as steel safety boxes and cabinets. At present‚ the company has two existing manufacturing facilities in Delaware and Iowa. The new appointed CEO of Metal-Works Corporation wants to re-configure the network for the company. The present configuration is believed to not be optimum. As an initiative to improve this situation‚ the CEO has decided to hire a consultant to analyze the current distribution centers

Introduction: This experiment was used to examine the hypothesis that: Osmosis is dependent on the concentrations of the substances involved. Diffusion is the passage of solute molecules from an area of high concentration to an area of low concentration (Campbell & Reece‚ 2005). An example is ammonia diffusing throughout a room. A solute is one of two components in a chemical solution. The solute is the substance dissolved in the solution. The solvent‚ the other component‚ is any liquid in

of higher concentration to areas of lower concentration. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane that only allows certain molecules to diffuse though (Lab Manual 7e‚ 2010). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no net movement will occur from one area to another. If two solutions have the same solute concentration‚ the solutions

A concentration camp is where people got captured and taken to. These people get taken by the Nazis and go to a camp. In these camps some torched‚ beaten‚ some have a disease. This was a place for punishment. Hitler got a group of people called the nazis and rounded up millions of people to tourche in these concentration camps. Concentration camps are a brutal place. Over 40‚000 men‚ women‚ babies‚ kids people of all sorts got taken. Some people tried to hide out but it didn’t really work out for

The Dreaded Story of Dachau A concentration camp refers to a camp or closed area where people are detained under brutal conditions usually having no access to legal rights of arrest and imprisonment that would normally be accepted in a democracy. Concentration camps played a large part in the mass killing of Jews in Europe lead by Adolf Hitler. An example of a concentration camp is Dachau. During the World War II‚ Jews were separated into two groups the healthy and the unhealthy. The unhealthy
