Extraction of Aluminium Aluminium ore is called bauxite. Bauxite contains aluminium oxide‚ water‚ iron oxide and other impurities. The purified dry ore‚ called alumina‚ is aluminium oxide (Al2O3). The alumina must be molten for electrolysis to work‚ since the ions are not free to move in the solid state. Unfortunately‚ alumina has a high melting point (2040 °C) and it is not practical to do electrolysis at such a high temperature. In the middle of the nineteenth century it was found that alumina

Ornamental Perennials The following is a list of the common plant names cross referenced to the scientific name of plants. The list represents some of the most popular varieties of perennial plants. The scientific names of plants is based on taxonomy‚ the science of plant classification. Each name has two parts‚ the genus and the specie. This is referred to as the binomial (two names)system founded by Linnaeus‚ a Swedish botanist. Some species will have a third name‚ called the subspecies‚ variety

Falafel‚ which is traditionally sold in very small and sometimes smelly cafeterias‚ is now sold in outlets that match in image and brand elements the biggest fast food brands known worldwide (maybe at the expense of its oriental past‚ with a somewhat western offering– the Sandwich‚ the coke‚ and yes the French fries). This somewhat Westernization has made the Journey possible‚ with Just Falafel becoming the biggest falafel franchise

1 in vapour state sulphur partly exists as S2 molecule which has 2 unpaired electrons in the antibondind pi orbitals jus lyk oxygen and thus exhibits paramagnetism. 2 An interhalogen compound is a molecule whose atom contains two or more different halogen atoms (fluorine‚ chlorine‚ bromine‚ iodine or astatine). Most interhalogen compounds known are binary (composed of only two distinct elements). Their formulas are generally XYn‚ where n = 1‚ 3‚ 5 or 7‚ and X is the less electronegative

This is important for the students to appreciate the knowledge of chemistry that is still new for themselves. Personally‚ I think that this chapter is an interesting chapter as it revealed the way of scientist produces the material around me. It also gives me new knowledge of the uses of chemical substances that I usually found in the laboratories. I hope‚ by learning this chapter‚ I will be more interested in learning chemistry as it will help me in the future. All the equations from this chapter
