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 ...

Neuro Transmission Positive Charge
488 wordsneurotransmitters play a central and critical role in our psychological existence, identity, and experience of the world Neurotransmitters are chemicals that communicate between nerves. In some ways, neurons are like computers: they receive messages, process those messages, and send out the results as new messages to other cells. In the case of neurons, messages consist of chemicals that interact with the outer surface of the cell membrane. This chemical interaction with the cell membrane causes...

Paddle Pop Stick 2 Co 3 Flame
663 wordsExperiments to determine the identity of metals by examining the colour of flame when samples of that metal are heated. The aim of this experiment was to find out whether different metals had different reactions when subjected to the flame of the Bunsen burner. This might then allow the classification and identification of certain metals if they have their own reactions, which will be different coloured flames for this experiment. It was hard for me to predict what would occur during the experim...

Aluminium Versus Aluminum Why A Difference In Spelling
504 wordsThe metal was named by the English chemist Sir Humphry Davy, even though he was unable to isolate it: that took another two decades work by others. He derived the name from the mineral called alumina, which itself had only been named in English by the chemist Joseph Black in 1790. Black took it from the French, who had based it on alum, a white mineral that had been used since ancient times for dyeing and tanning, among other things. Chemically, this is potassium aluminium sulphate (a name which...

Plasma Membrane Passive Transport
834 wordsBeing one of the most important components of a cell, the plasma membrane, or cell membrane plays a huge role in regulating how things get in and out of cells. The plasma membranes unique structure enables it to let only certain molecules pass through the cell. This ability is called selective permeability. Most of the plasma membrane in most cells is made up of a phospholipid bilayer with proteins either embedded into it or sticking out from either side of the membrane. The heads of the phospho...

H 2 O 2 O 2
828 wordsPurpose - The purpose of this lab is to use a chemical titration to measure and them calculate the rate of conversion of hydrogen peroxide (H 2 O 2) to water and oxygen gas using the enzyme catalase. Hypothesis - The rate of enzymatically-catalyzed reactions can be determined by taking time reactions at different time intervals. When the rates are plotted on a graph, the rate of the reaction is the slope of the linear portion of the curve. To determine a rate, any two points on the straight-line...
