1. What is the impact of the Clean Air Act amendments of 1990 on the Southern Company’s Bowen plant? The Clean Air Act amendments of 1990 regulate the emissions of sulfur dioxide starting in 1995. The intention of this legislation is to control the formation of acid rain. Between 1995 and 1999‚ the Bowen plant will receive allowances to emit 254‚580 tons of sulfur dioxide per year. Starting in 2000‚ the Bowen plant will receive allowances to emit 122‚198 tons of sulfur dioxide per year. To comply

03.04 Valence Electrons and Bonding Individual neutral atoms are rarely found in nature. The noble gases are the only elements that are found as single atoms more often than they are found in compounds. Atoms are held together in compounds by electrostatic attraction between positive nuclei and negative electrons. This attraction holds atoms together in a chemical bond‚ a link between two atoms resulting from the mutual attraction of their nuclei for valence electrons. All chemical bonds involve

by adding high sodium‚ low sodium‚ and very low sodium into three individual test tubes ‚ and measured the height of the foam then low sodium would have the highest reaction rate‚ this is because changes in the concentration of salt alter the electrostatic interactions between charged amino acids‚ so if salt is added the ability of enzymes to bind to the substrate is altered and the enzyme may or may not be able to bind to it. If I change the environment of the catalyst by adding room temperature

Separation by difference in particle size: Sieving: - Is a way pf separating mixtures of solids‚ or solids and liquids with different sized particles - The mixture is poured through a sieve and the particles smaller than the sieve pass through while the larger particles are trapped by the sieve - The are commonly used for cooking - E.g. a mixture of rice and water is poured through a sieve to capture rice and remove the water Filtration - Is a technique commonly used for mixtures of solids and liquid

loudspeaker produces a magnetic field which then causes a coil or magnet to move. The coil or magnet is connected to the diaphragm. There are more speakers than just the horn‚ such as‚ such as‚ electrodynamic loudspeaker‚ flat panel - planar‚ electrostatic‚ multi-cell diaphragm and piezoelectric. Speakers are used to produce sound. Sound is an energy which is created by passing through a gas or liquid medium. Sound is measured in Frequency and Decibels. Decibels is how loud the sound being produced

The Ionic Lattice In most ionic compounds‚ the anions are much larger than the cations‚ and it is the anions which form the crystal array. The smaller cations reside in the holes between the anions. Basic Concepts: 1. Ions are assumed to be charged‚ incompressible‚ nonpolarizable spheres. 2. Ions try to surround themselves with as many ions of opposite charge as closely as possible. Usually in the packing arrangement‚ the cation is just large enough to allow te anions to surround it without

types of bonds include metallic bonds and hydrogen bonding. The attractive forces between molecules in a liquid can be characterized as van der Waals bonds. What is an Ionic Bond? An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed due to the attraction between an atom that has lost one or more electron (known as a cation) and an atom that has gained one or more electrons (known as an anion). Usually‚
