The Rif Army The war of the Rif, also known as the second Moroccan War, was fought from 1920 to 1926. Spain, France and the Moroccan Berbers, of the Rif’s mountain region, had joined forces to take control and divide the country of Morocco into even parts. The reason behind this was because they wanted power, like most imperializing countries strive for. What the invading force did not know was that this was not going to be an easy task. The Rifs, the indigenous tribes of Morocco had joined forces

invented and improved. Some of these weapons included tanks, chemical and biochemical weapons, grenades, and machine guns. Chemical Warfare was used for the first time on a large scale in World War I. There are two main types of chemical warfare, one affects the surface of the body they come in contact with and the other affects the nervous system. Almost all chemical warfare weapons needed to be inhaled to cause severe damage or death. Chemicals that caused neurological damage acted by blocking the transmission

spring also brings us a medley of a different sort-a toxic soup of chemicals. Much of this soup isn't thrust upon us from the outside; disturbingly, we choose to expose ourselves, our children, our neighbors, and our pets to these harmful chemicals. In 2013, Americans spent over $700,000,000 on pesticides (cumulatively weighing over sixty-five million pounds) for use on their lawns alone (1). One would think

Aim: To find out how varying the size of beads containing yeast varies the rate of activity of catalase in a fermentation reaction of hydrogen peroxide with immobilised enzymes. A catalyst is a substance that speeds up the rate of a chemical reaction, without itself being used up in the process however it maybe affected physically i.e. degradation of the surface of the catalyst. Catalysts work by reducing the activation energy needed for a particular reaction by offering

of this experiment is to find the order of t-BB graphically, to find the k (rate constant) at 0˚ C and at room temperature, also to find the Ea (activation energy). Principles: Several different chemical kinetic principles were used in this experiment. The reaction rates of this chemical equation were determined experimentally. This then allowed the reaction mechanisms (i.e. orders of each component, rate constant, etc.). These mechanisms were ultimately determined to be compiled to form

Chemical Castration is supposed to be a way that the government can somehow reduce the rates of rapes and molestation. Not everybody believes in this procedure. I am one of those people who do not believe in this procedure. I don’t think that this could be affective, and won’t benefit our country. A bill was passed recently saying that if a child molester was convicted twice of molesting a child under the age of thirteen years, they would be court ordered to do this procedure. In a recent article

Lab Report on Measuring the Rate of Conversion of Hydrogen Peroxide using Enzyme Catalysis In essence, the main objective was to use chemical titration to measure and then calculate the rate of conversion of hydrogen peroxide (H2O2) to water and oxygen by using the enzyme catalase. Other purposes of the lab were; to measure the effects of changes of temperature, pH, enzymes concentration, and substrate concentration on rates of an enzyme. The lab was also an opportunity to see a catalyzed reaction

Chemical Weapons - Weapons of Mass Destruction Chemical weapons and their use is one of the most important issues facing the world today. Not only is the use of such weapons highly controversial, but also the very idea of such weapons of mass destruction being in the hands of dangerous leaders. Next to nuclear weapons they are the most feared, and the prospect of these weapons not only concerns people, but also frightens them. As a result of these fears, America has entered a new war that could

Gas Equilibriums: examples of Reversible Reactions Q1. Identify the general chemical and physical characteristics of gas equilibriums as a group. Explain the forward and reverse reaction mechanisms. Use nitrogen dioxide and hydrogen iodide as examples and explain how equilibrium is reached. The general chemical characteristic of gas equilibriums is when the concentrations of reactants and products do not change with time. This is known as the state of reversible reaction. At this state, pressure
