The Holocaust is a defining moment of the world’s history. The horrific annihilation of innocent Jews and Europeans will forever be etched into the minds of humans all around the world. The haunting outcomes of war and terrorism will forever be remembered throughout time. However‚ these defining moments in the history/making of the world will only be remembered if people continue to teach about these events and remember the people involved in them. Throughout history‚ there have been many events

Chapter 1 Chemical Reactions and Equations Q.1. Why should magnesium ribbon be cleaned before burning in air ? Ans: Magnesium ribbon is a very reactive metal. When stored it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide being a stable compound prevents further reaction of magnesium with oxygen. The magnesium is cleaned before burning in air to remove this layer so that the metal can be exposed to air properly. Q.2. Write the balanced

A miser is ever in want. --Greek proverb Preparing to experiment You will be provided with the following materials: Redox Reactions Reactions involving oxidation and reduction processes are very important in our everyday world. They make batteries work and cause metals to corrode (or help to prevent their corrosion). They enable us to obtain heat by burning fuels--in factories and in our bodies. Many redox reactions are complex. However‚ combustion and synthesis (from elements) are two

Holocaust Most people know about the tragic event that happened in 1942 called the Holocaust. Krystyna and Pavl both wanted freedom the Nazi’s because they were both trapped in a Ghetto during World War 2 They were there because they were Jewish. The Nazi’s were going to kill Krystyna and Pavl. What Kristina did was she hid in the sewer for about 15 months and Pavl died 2 years after he went to a concentration camp. The two stories take place when World War 2 was going on‚ in both texts it talks

Redox reactions (Redox terminology‚ galvanic cells‚ standard electrode potentials‚ strength of oxidizing/reducing agents‚ corrosion and protection against it) Oxidation is defined as the loss of electrons and reduction is defined as the gain of electrons. Oxidizing agents‚ such as oxygen are defined as substances which accept electrons; reducing agents are substances which donate electrons. Redox reactions are: a) The reactions of metals with non-metals 2Na+Cl2→2Na+Cl- b) The reactions

Aldol In this preparative lab‚ an aldol (trans-p-anisalacetophenone) was produced from the reaction between p-anisaldehyde and acetophenone with the presence sodium hydroxide. The reaction also showed the importance of an enolate and the role it played in the mechanism. Sodium hydroxide acts as a catalyst in this experiment and is chosen because of its basic conditions and pH. The acetophenone carries an alpha hydrogen that has a pKa between 18 and 20. This alpha hydrogen is acidic because of its

Coursework Rates of Reaction Research The rate of reaction tells us how quickly a chemical reaction takes place. It is important for people in industry to know how fast a reaction goes. They have to know exactly how much of their product they can make each hour‚ day or week. In a shampoo factory‚ the rate might be 100 bottles per minute. We can’t work out the rate of a reaction from its chemical equation. Equations can only tells us how much product we can get. They don’t say how quickly

They experimented in various ways‚ including how to combat hypothermia. These experiments left massive amounts of dead test subjects. All of these

the term applied to a group of camps built by Nazi German during World War II with the express purpose of killing the "enemies" of the Nazi regime (Jews‚ Roma Gypsies‚ prisoners of Soviet war‚ as well as Polish and other). All this is part of the Holocaust and called Final Solution of the Jewish question‚ the plan to (in the words of Nazi) “German lands clean of the Jewish people”. These fields are also known as "death camps". The most common method of execution in these camps was by Zyklon B a gas

BIOL2220 Lab 3: Hill Reaction Introduction In 1937‚ Robert Hill discovered that isolated chloroplasts can generate oxygen when they are illuminated in the presence of a suitable electron acceptor‚ even in the absence of carbon dioxide. This finding was a landmark in the study of photosynthesis because it established that the source of the electrons used in the light reactions is water. It also confirmed that the released oxygen is derived from water instead of carbon dioxide. In chloroplasts
