Describe the characteristic features of each minerals. Gold- soft‚ lustrous yellow‚ malleable metal. It is one of the transition metals. It is highly sought after precious metal in jewelry Copper- is valued for strength‚ malleability‚ ductility‚ and ability to conduct electricity and heat. It is also non-magnetic‚ resists wear‚ and forms

just a refinery’s by-product any more‚ but a real alternative costeffective fuel that can be successfully fired in CFB boilers either alone or in blends with coal. With its specific ash content‚ which is typically lower than 1 percent and very high sulfur‚ petcoke is an effective source of energy increasing plant economy. Foster Wheeler CFB technology allows efficient combustion of petroleum coke. Numerous references are located mostly in United States or China reaching utility capacities of 300 MWe

Environmental Science – EVS 1001 2 4/23/13 Week 2 Individual Work There are human impacts that deal with four chemical cycles. The first cycle is to do with carbon. The second is to do with phosphorus. The third cycle is nitrogen. And the fourth cycle is sulfur. We will look at each one and how they impact humans and examples. Carbon effects human impact. “Human intrusion into the carbon cycle is significant. As we will see shortly‚ we are diverting (or removing) 40 % of the photosynthetic productivity

antitumor agents was originally utilized for the purpose of chemical warfare‚ most prominently so in World War I. Sulfur mustard‚ the precursor to phosphoramide drugs‚ was employed to great effect as a wounding agent in the characteristic trench warfare of WWI; Being a dense gas‚ sulfur mustard settled in trenches and created persistent environmental hazards for troops. Exposure to sulfur mustard‚ while usually non-fatal‚ induced symptoms of blistering‚ respiratory illness‚ inflammation of the eyes

hydrololic. The water cycle is a hydrologic cycle that moves water in the biosphere through evaporation‚ condensation and precipitation. Two sedimentary cycles are the sulfur and phosphorous cycle. Their main reservoirs are in soil and rock sediments. Sulfur enters the cycle as hydrogen sulfide and is oxidized to sulfur dioxide. Sulfur dioxide and water vapor makes sulfuic acid in the rainfall. It is then absorbed by plant roots and turned into amino acids traveling through the food chain and released

problem can be overcome. Acid rain is produced‚ when automobiles‚ smelters‚ power plants‚ and other industrial factories burn fossil fuels such as gasoline‚ coal‚ and fuel oils. When combusted‚ the non renewable resources release pollutants such as sulfur‚ carbon and nitrogen oxides into the air. These oxide combine with the humidity in the air and form sulfuric‚ nitric and carbonic acid. This acidic solution eventually condenses in the air and comes back down to the earth in any from of precipitation

Stab inoculating the SIM media for these tests will also show if the organism produces sulfur or indole and if it is motile. If sulfur is present‚ then the medium will be black‚ if it produces indole‚ the medium will be red‚ and if it is motile‚ there will be growth throughout the tube. I also grew the organism on MacConkey agar. After inoculation‚ visible colonies
