These countries included Germany‚ France‚ Holland‚ Norway‚ Poland‚ Russia‚ Yugoslavia‚ Austria‚ Belgium‚ Czechoslovakia‚ Finland‚ Italy‚ Latvia‚ Lithuania and Estonia. Most of the camps were constructed near railways which was mainly

Effects of Different Concentration of Catalyse on Hydrogen Peroxide Aim: In this investigation I will try to find how long it takes for the filter paper disc to rise up whilst varying the amounts of concentration of catalyse. Prediction: I predict that the lower the concentration of catalyse the longer it will take for the filter paper disc to rise to the surface of the tube. Equipment: 1. Hydrogen peroxide in a container 2. Flat bottom tube 3. Tweezers 4. Filter paper

MEMORANDUM From: To: Subject: Calcium Chloride Best Purchase for Deicing Enclosures: (1) Data Record (2) Data Treatment (3) Environment Impact Research After hours of vigorous examination‚ we have come to the conclusion that calcium chloride (CaCl2) would be the best deicer to use on a naval base over sodium chloride (NaCl) and ethylene glycol (C2H6O2). In order to melt ice‚ deicers lower the freezing point so that the ice melts at lower temperatures. CaCl2 has

Experiment 4 Synthesis of Salicylic Acid Introduction Throughout history‚ botanical extracts have been used as medicines. Approximately 30% of all medicines have a plant origin. This number increases to 60% if you consider medicines that at one time were derived from plants‚ but have been synthesized in the laboratory. Salicylic acid is a white crystalline compound that can be isolated from the bark of birch trees. Since it is a valuable substance that can be isolated from nature‚ it is called

Extraction of R’-NH2 For both of the organic acid and organic base extraction‚ the addition of the respective inorganic acid or inorganic base (HCl or NaOH) to the three-component mixture caused an immiscible appearance of the solution in the separatory funnel. By briskly shaking the separatory funnel with the mixed components created a build up of pressure which was released through the stopcock forming small disappearing bubbles within the tip of the separatory funnel. Once the funnel was placed

Concentration Camps Did you realize that over 1 million people died at the Auschwitz camp!Auschwitz was the biggest concentration camp.It was the only camp left after the end of World War 2. Concentration camps were designed to remove Jews from Europe. They were a strenuous and cruel place to live. The concentration camps were created in 1933-1945 by Hitler and the Nazis. Auschwitz was the largest concentration camp. Hitler and the Nazis made Jews‚ and people they did not like‚ build the camps
