confirming Beer-Lambert’s Law was a successful method in determining the molar concentration of a sample within a composition that is unidentified. Absorption spectroscopy is used in order to determine the ε value; ε was calculated to be .0566. Introduction: The purpose of the Absorption Spectroscopy experiment is to evaluate the reliability and accuracy when using Beer-Lambert Law to determine the concentration of a specific sample within a mixture solution. The number of electrons being

Substrate concentration and yeast catalase Aim: To see how the substrate concentration in hydrogen peroxide affects the rate of an enzyme controlled reaction using yeast catalase. Introduction: An enzyme is a biological catalyst made of protein. Enzymes are protein molecules found in living organisms and in this case I will use a yeast catalase. Catalase is an enzyme that catalyzes the reduction of hydrogen peroxide. Hydrogen peroxide is a poisonous by-product of metabolism‚ so it is very

Baaqir Salaam October 10‚ 2013 English 3A Killing Centers And Concentration Camps; The Institutions of Nazi Germany In killing centers across Germany approximately six million Jews were killed‚ and even more were imprisoned in the work camps. To understand what killing centers and concentration camps were it is beneficial to think about what it was like to be inside of one. In killing centers there wasn ’t much to see. The Jews or Africans or whoever was deemed unworthy of living by the Germans

The main concentration camp was Auschwitz. Auschwitz was the largest camp that was created by the Nazi. It was broken down into three main camps. The first camp was built in April 1940. It was known as Auschwitz 1. The second camp was built in October 1941. It was known as Birkenau. The third Camp was built in October 1942. It was known as Buna. The number of Victims in the Auschwitz Complex alone were absurd. The SS and police killed about 1.1 million people of all different backgrounds out of the

Introduction In this experiment I aim to find out if caffeine has an effect on the heart rate of daphnia. Daphnia are water fleas that have a sort of heart that we can see in magnification. We can count the number of heart beats in a minute of a regular daphnia and try and get a new one with the same specifications as the old one that may have died. It is also a good idea to get a new one as we want to see how much it affects it from ordinary instead of adding the caffeine one after another

From previous experiments we ’ve learned that salt is extracted from green beans. To be more specific: salt is extracted from when the beans are cooked in water in which salt has been dissolved. This experiment is based upon the osmoses theory. According to this theory the cell walls of the green beans are what we call a semi permeable membrane. This membrane only lets water through and not the substance that is dissolved into the water‚ as in this case is NaCl. Because the concentration of the salt

Experiment 2: Laboratory Techniques and Measurements Course Number: CHE 111 Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel‚ which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric
