Overview Chemical Warfare is using the chemical properties of a substance to your advantage during war. This has been going on for centuries. Even the most basic forms of weapons were used. People have been putting poison on the end of their spears and arrows since they have been around. Over the years‚ it has also developed into much more advanced chemistry. In this article‚ I am going to focus on the more advanced‚ modern uses of chemical warfare in World War I and World War II. World War

Introduction In these modern times‚ are nuclear power plants feasible to every nation around the world? How about in a nation experiencing the toll of depletion of resources‚ destruction of nature and poverty at the same time; is it still an answer for economic growth? Is the construction of nuclear power plants an aid for the spur of development of a country or a growing threat to the environment? Do nuclear power plants serve the people best or destroy the nature best? Nuclear power plants are

1. Atomic and Molecular Structure a. Students know how to relate the position of an element in the periodic table to its atomic number and atomic mass. The Periodic Table organizes elements by their atomic number - from hydrogen (1) to whatever is the highest one currently known (>105). It is arranged so that similiar members fall in a list such as Chlorine Bromine etc.. The average atomic weight is usually shown with each element‚ but due to isotopes (caused buy nuclear varations)

choice for nuclear power plants. Uranium is special because it can go through what is called induced fission. Induced fission is when a free neutron is fired at an atom (like uranium). The atom will absorb the neutron‚ and immediately becomes unstable and splits apart. When the uranium atom splits‚ it will split into two separate atoms and expels two or three neutrons depending on how the atom splits. A single uranium atom‚ when going through induced fission‚ will release about 200 MeV (million electron

Chapter 13 – States of Matter Pressure (P) – the amount of force per unit area. Pressure=F/a or P=F/a Pascal’s Principle “Any change in pressure at a point on a confined fluid is transmitted throughout the fluid”. Any change is transmitted throughout the fluid. Buoyancy & Archimedes Principle “When an object is submerged in a fluid‚ it displaces a certain volume of that fluid. The amount of force pushing upward on the object is equal to the density of the fluid (Ï) times the acceleration

when the arrangement of the atoms and electrons in the carbon-based fuel and oxygen is less stable than the organization of atoms and electrons in the carbon dioxide. Nuclear reaction is controlled by regulating the number of neutrons that are created. Control rods absorb neutrons are inserted between the uranium fuel rods. They are increased or reduced in order to keep a constant release of energy. Strong nuclear forces are involved together with the weak interaction. Nuclear energy starts off from
