Hall Heroult Process Bauxite Mined Aluminum
1,057 words... s, and soils contain aluminum compounds, but aluminum can be made inexpensively only from bauxite. Bauxite is the name for any ore that has a large amount of aluminum hydroxide- a chemical combination of aluminum oxide and water. Aluminum oxide, also called alumina, is the compound from which aluminum is made. Most bauxite consists of 30 to 60 percent alumina and 12 to 30 percent water. It also contains iron oxide, silica, and titanium oxide. The color of bauxite depends chiefly on how much ...

Sodium Chloride Earth Crust
745 wordsSodium has an atomic number of 11 and a mass of about 23 g. It is a silvery white-metallic element classified under the alkali metals. Sodium has been known since early times and was used by the people of Mesopotamia and Egypt to make glasses. Sodium is the sixth most common element found on the earth. It is usually not found in nature but more often in compounds such as salt (NaCl). Sodium conducts heat and electricity easily. Without this element life could not exist. Each compound is used for...

Natural Selection And Diseases
1,383 wordsCystic fibrosis, Tay-Sachs, and hypertension are three very different, yet deadly diseases. The question arises how these diseases have survived for so long. Three articles attempt to uncover the mystery behind these diseases. It has been found that there were benefits to each of these diseases, which allowed the allele to remain in the community for such a long period of time. Natural selection plays a large part in the success of these conditions. First, cystic fibrosis has been found to be pr...

Cystic Fibrosis Endoplasmic Reticulum
717 wordsCystic Fibrosis Commonly found in young children, Cystic Fibrosis is an inherited disease that is caused by a genetic disorder. The disease originates in the production of a critical protein that transports chloride ions from one place to another called a cystic fibrosis transmembrane conductance regulator (CFTR). The DNA of an infected person is missing three building blocks called nucleotides causing the CFTR protein to be missing one amino acid called phenylalanine. Normally, a healthy CFTR p...
