An explosion is a type of spontaneous chemical reaction that once it is initiated it will be driven by both a large exothermic change and a large positive entropy change in going from reactants to products, thereby constituting a thermodynamically process in which it propagates very rapidly, but in some cases the rate decreases thereby resulting in a slower depleting form of the explosive.
Throughout past to modern time we are constantly hearing about different explosives being used to cause destruction and mayhem. But there are many types of explosives that all fall into four main groups, Primary, Low, High, and Blasting Agents. In history though early thermal weapons, such as Greek fire, have existed since ancient times, the first widely used explosive in warfare and mining was black powder, which was invented during 9th century China. This material was sensitive to water, and was evolved in causing lots of dark smoke and pollution. The first useful offical explosive was stronger than black powder and they called it nitroglycerin, which was developed in 1847. As nitroglycerin was unstable, it was replaced by nitrocellulose, a smokeless powdered dynamite and gelignite. In World War I saw the introduction of trinitrotoluene in naval shells. But in World War II it was seen as an extensive use of new explosives. In turn, these have largely been replaced by modern explosives such as C-4 , nitrate fuel oil mixtures and ammonium nitrate-base water gels now account for seventy percent of the explosive market .The increased availability of chemicals has allowed the construction of improvised explosive devices to increase over time. In which leaving the explosive substance that contains a large amount of energy to be stored in a chemical ...

...ion. Although they are depicted through color it doesn't literally mean that the water will only turn those two specific colors when contaminated by the chemicals of the explosives. All of the colors depend on the light to help it evolve into something different or change different chemical composition that are presented at the time. Also the principal contaminants in the pinkwater is trinitrotoluene and cyclotrimethylene trinitramine which are transferred from discharges from the army ammunition plant.Some are under ambient environmental conditions with explosives being highly persistent in soils and groundwater, they are now showing a resistance to naturally occurring volatilization, biodegradation, and hydrolysis. Which is making it harder to get clean water in poor economic cities due to the amount of contamination from the chemicals released from the explosive.
McVeigh to the crime…” (LA Times). This evidence includes a pair of ear buds recovered from McVeigh after he was detained for operating a vehicle without a license plate and possession of a concealed weapon. It is the intent of the prosecution to show that the ear buds contained trace amounts of pentaerythritol tetranitrate which is often found at the site of bombings as well as nitroglycerin and ethylene glycol dinitrate, which are used in high explosives and the production of dynamite (LA
Looking back at how the chemical weaponry expanded starting in the beginning of World War 1, it all began with Tear gas which was used by the French in August of 1914. Those techniques have been used in ancient times. Moving forward eight months in to the war the Germans have been giving great study in to the development of chemical weapons due to the first usage from the French and witnessed its great effectiveness and were the first to use it in a large scale.
Both 1984 and The Handmaid’s Tale are dystopian novels, however, these books are a lot more complex than mere portrayals of dystopia, it can be argued that they are explorations of dystopia rather than mere portrayals. In order to explore dystopia, many themes must be considered, such as; feminism, love and repression. Nonetheless, it is apparent that human characteristics are the driving point of the two novels, predominantly, the depiction of human resilience. In an imperfect world, it is important to have certain qualities which, if plentiful, it can mean success, whereas if it lacks, it can mean failure, this characteristic is resilience. The protagonists in each novel, Winston in 1984 and Offred in The Handmaid’s Tale face situations which leave them both in disarray, and both even consider suicide. The authors tentatively highlight human resilience, its limits and most importantly its strengths into the two novels.
“‘They score! Henderson has scored for Canada!’” Foster Hewitt wordlessly described” (Pelletier) when Paul Henderson scored the series-winning goal. This allowed Canada to win the 1972 Summit Series, a moment that no one would ever forget since it all happened during the climax of the Cold War. Prior to this, the Soviets had won the previous three Olympic gold metals since Canada could not use its NHL players. Thus, this provided Canada with the chance to play hockey against the USSR using its best players. This raised the question: if Canada were able to send its best players, would it still be enough to beat the Soviets? Everyone in Canada was certain that the Soviets would not win a single game, but little did they know they underestimated the extent of the Soviets abilities. Tied in the last few minutes of game eight, Canada had to score or they would lose the series. However, when Paul Henderson scored the game-winning goal, never before had a single sporting event meant so much to Canadians. Therefore, Paul Henderson’s goal is a defining moment for Canada in the twentieth century becauseit provided Canada with the opportunity to evolve hockey, proved that Canada and our democratic society were superior to the USSR and their communist society, and brought citizens together to unify Canada as a nation.

The Hunger Games was a critically acclaimed movie when it came out; however, some critics would argue that the movie can be sometimes too violent for its intended audience. In this essay I would dissert Brian Bethune’s essay “Dystopia Now” in order to find its weaknesses and compare the movie Battle Royale with his essay.

“You never really understand a person until you consider things from his point of view – until you climb into his skin and walk around in it.” Harper Lee identifies many charcters in the beginning of this book. She was very descriptive of all the characters in the beginning of the book. Each character was described from Scout’s point of view. Throughout the book, Lee lets the reader see some of the characters in their natural environments. They are still written through Scout’s eyes, but instead of passing by them on the sidewalk, Scout is in their home sitting with them, or hearing personal stories about them. Three of these characters that Scout points out specifically are Jem Finch, Aunt Alexandra, and Tom Robinson.

Mustard gas was not the only example of chemical weaponry used during World War I. The first example of this was the Germans use of a gas called phosgene in mid-1915, which caused drastic damage to the lungs (Mack 2). The Germans began using mustard gas in 1916 and soon both sides began to use poison gas as a weapon. At a lab at American University, which at its peak employed over 1,200 scientists specifically to create chemical weapons for the war, a new gas called Lewisite was developed. Lewisite poisoned its victims through the skin and rendered gas masks useless against it. During the war as many as 50 different gases were used by both sides (Mack 2). When the war e...
The traditional high school A-F grading system no longer reflects an accurate measurement of student success. Providing a new system where grades are measured by the rank of the student in the class will provide a system more honest than before, it will benefit students and prospective colleges. Changing the grading scale to a system where students are ranked from a curve based off the total percentage of points potentially earned in the course.

Blow out Blow Out is a mystery thriller film from 1981 featuring John Travolta and Nancy Allen. It is both written and directed by Brian De Palma, who has since also directed movies such as Mission: Impossible and Scarface. To begin with, I think this film was very interesting to watch.
A bomb is a container filled with an explosive, incendiary matter, or gas that can be dropped, hurled, or set in place to be detonated by an attached exploding device. It may range in design from a homemade device used by terrorists, assassins, or clandestine raiders to a sophisticated weapon of war. The original bomb, an ancestor of the hand-thrown GRENADE, was a simple container filled with black powder (see GUNPOWDER), which was set off by a fuse lit by the thrower. In the 16th century, the Dutch invented a more sophisticated version, the MORTAR bomb, a round iron container filled with black powder that was set off when a fuse was ignited by the detonation of a propelling charge in the base of the mortar tube. By varying the length of the fuse, the bomb's time of detonation could be adjusted; thus, a bomb could burst in air.
