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...

Life On Earth H 2 O
726 wordsThe first thing water reminds us of is the clear liquid in our water bottles. However, water is more than a normal substance. Water is the beginning and the continual of life on earth. Because of its many unique properties, water was able to start life on our planet. The simple structure of H 2 O is the source of all water's properties. With two hydrogen atoms sticking to an oxygen atom in a tetrahedron shape, water is considered as a polar molecule. Because oxygen is very electronegative, it pu...

Excess Dietary Protein And Calcium
1,202 words... sodium in the water surrounding it. Ninety-nine percent of the calcium is in bone. Bone responds to acid by chemical reactions with the rapid release of carbonate, citrate, and sodium from the hydration shell (Barzel 1051). Therefore, in response to chronic acid stress such as an acid-ash diet, cellular responses mobilize bone and calcium as a buffer. As the result, more calcium will be reserved from bone, and excreted in urine. The effects can be mild in temporary cases, such as hypercalciu...

H 2 O Metric Tons
485 wordsMagnesium, symbol Mg, is a silvery white metallic element that is relatively un-reactive. In group 2 of the periodic table, magnesium is one of the alkaline earth metals. The atomic number of magnesium is 12. Properties and Occurrence The metal, first isolated by the British chemist Sir Humphry Davy in 1808, is obtained today chiefly by electrolysis of fused magnesium chloride. Magnesium is malleable and ductile when heated. With the exception of beryllium, it is the lightest metal that remains ...

Life On Earth B And C
1,459 wordsCarbon dioxide is a colorless, odorless, non-toxic, and slightly acid-tasting gas. Sometimes referred to as a carbonic acid gas, the molecule consists of one atom of carbon joined to two atoms of oxygen. It occurs naturally in the atmospheres of many planets, including that of earth. Carbon dioxide is uniformly distributed over the earths surface at a concentration of about 0. 033 %, or 330 parts per million. It was called fixed air by the Scottish chemist and physician Joseph Black in the 1750 ...

Janssen originally thought it was sodium, but Joseph Norman Lockyer noticed that it didnt correspond to the D 1 and D 2 lines of sodium. He named it the D 3 line. Lockyer said that the element D 3 was unknown on Earth. He and Edward Franklin concluded on the name Helios after the Greek god of the sun. Helium is found everywhere in space. All natural gases have at least a little bit helium in them. ...
