The elemental makeup of a compound defines its chemical identity, and chemical formulas are the most succinct way of representing this elemental makeup. When a compound''s formula is unknown, measuring the mass of each of its constituent elements is often the first step in the process of determining the formula experimentally.

Hematite is an iron oxide mineral which occurs in most metamorphic and sedimentary rocks. Hematite often occurs intermixed with Quartz. Crystalline rose forms of Hematite make fine specimens for collections. Specular Hematite included with Mica, also known as Specularite, display a wonderful sparkling star effect.
Magnetite has the chemical formula Fe3O4, while hematite is Fe2O3. By mass, hematite is a bit under 70% iron while magnetite is a little over 72% iron, so in samples of equal mass there is more ...
Jan 28, 2012· Magnetite is an iron oxide with the chemical formula Fe 3 O 4 whereas hematite is an iron oxide with the chemical formula Fe 2 O 3. Magnetite iron is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state. This is the key difference between magnetite and hematite.
Hematite, also spelled as haematite, is a common iron oxide with the formula Fe 2 O 3 and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).

Hematite was largely used in the past as a red and brown pigment, although nowadays cheaper sources have been substituted. Well formed Hematite crystals are popular among mineral collectors, and tumbled, highly lustrous Hematite from Brazil makes a very popular, inexpensive specimen for amateur collectors. Hematite is also used as a minor gemstone.
Sep 30, 2019· Haematite is the principal ore of Iron (Fe). It''s empirical formula is Fe2O3 (with Fe in the 3+ valency). There are also other ores for Iron, including FeO (Fe 2+) and Magnetite often quoted incorrectly as Fe3O4. In fact the composition of Magneti...
Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturallyoccurring minerals on Earth.
