Hematite has a chemical formula Fe2O3, indicating that it consists of two iron (Fe) atoms bonded to three oxygen (O) atoms. It has a high iron content and is one of the most abundant iron ores found on Earth. It is often found in sedimentary, metamorphic, and igneous rocks. One of the notable characteristics of hematite is its streak.

The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things - nails, wire, car bodies, ship building, girders and bridges amongst others. High carbon steel: High carbon steel contains up to about 1.5% of carbon.

To calculate the percent composition, the masses of C, H, and O in a known mass of C 9 H 8 O 4 are needed. It is convenient to consider 1 mol of C 9 H 8 O 4 and use its molar mass (180.159 g/mole, determined from the chemical formula) to calculate the percentages of each of its elements: %C = 9mol C × molar mass C molar massC9H8O4 × 100 = 9 ...

The Hall-Heroult process is widely used in the extraction of aluminium. In Hall-Heroults process, pure Al 2 O 3 is mixed with CaF 2 or Na 3 AlF 6. This results in lowering the melting point of the mixture and increases its ability to conduct electricity. A steel vessel with a lining of carbon and graphite rods is used.
