A chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound, using a single line of chemical element symbols and numbers.
Hence, the formula Ca 3 (PO 4) 2 is correct. On the basis of above steps the formulae of some ionic compounds are given in Table 12.4. Table 12.4. Writing Formula of an Ionic Compound. SOLVED EXAMPLES Example 12.1 Write down the formulae of (i) sodium oxide (ii) aluminium chloride
Copper is not difficult to extract from it ores, but mineable deposits were relatively rare. Some, such as the copper mine at Falun, Sweden, date from the 1200s, were the source of great wealth. One way to extract the metal was to roast the sulfide ore then leach out the copper …
Bauxite is the primary ore of aluminum. Almost all of the aluminum that has ever been produced has been extracted from bauxite. The United States has a few small bauxite deposits but at least 99% of the bauxite used in the United States is imported. The United States is also a major importer of aluminum metal.
The first element in the formula is given the neutral element name, and the second one is named by replacing the ending of the neutral element name with -ide. A prefix is used in front of each element name to indicate how many atoms of that element are present:
Aluminum must be refined from ore Although aluminum is the most common metal found on Earth (totaling 8 percent of the planet's crust), the metal is too reactive with other elements to occur naturally. Bauxite ore, refined through two processes, is the primary source of aluminum.
Write the symbol beginning with the symbol that is first in the name and include the subscript after each symbol. Ca 3 N 2. Formula writing with Polyatomic Ions. 1.

Apr 06, 2008· Aluminium ore is called Bauxite. Bauxite is a rock which may consist of the minerals gibbsite (Al2O3), boehmite (γ-AlO(OH)) or diaspore (α-AlO(OH)) in …
Ores -Those minerals from which the metals are extracted commercially and economically and with minimum effort are called Ores of Metals. Aluminium, for example, is the most common metal in the Earth's crust, occurring in all sorts of minerals.
Ore of metals are having geographical names . You can find ores names in Geography of meta book . Primary names for any metal is decided its component as oxide, sulphide, complex etc . some metal which is found as in native state have no ore and name as it is ex Gold .
Usually, when you hear about alum it is in reference to potassium alum, which is the hydrated form of potassium aluminum sulfate and has the chemical formula KAl(SO 4) 2 ·12H 2 O. However, any of the compounds with the empirical formula AB(SO 4 ) 2 ·12H 2 O are considered to be an alum.

Write the name and formula of the ores of: a)Aluminium. b)Copper. Share with your friends. 2 > a). Ore of aluminium (Al) is : Bauxite: it is a mixture of iron oxide, silicon oxide, titanium oxide and aluminium oxide as . Al 2 O 3 + SiO 2 + TiO 2 + Fe 2 O 3 . Cryolite: Na 3 AlF 6 . b).
The formula for aluminum oxide is Al_2O_3. The correct answer is Al_2O_3. Let us see how we got the answer; Look at the electronic arrangement of Al and O atoms. Al ( Z= 13) has 13 electrons with following electronic configuration. 1s^22s^22p^63s^23p^1 It loses three electron in its 3s and 3p subshell to achieve stability and forms ion Al^(3+).
4. Write the formula of aluminum sulfate. The oxidation number of aluminum, Al, as listed in Table 1, is +3. The oxidation number of sulfate, SO4 is -2. If the formula is written as: AlSO4 the sum of the oxidation numbers is +3 + (-2) = +1. Addition of a second sulfate ion will increase the negative oxidation number and give the formula: AlSO4SO4
Extraction of Metals. Extraction of Aluminium - Electrolysis Cell.. The steel container is coated with carbon and this is used as the negative electrode ().. Aluminium oxide (Al 2 O 3) is an ionic compound. When it is melted the Al 3+ and O 2-ions are free to move and conduct electricity. Electrolysis of the alumina/cryolite solution gives aluminium at the cathode and oxygen at the anode.
