Is magnetite an artificial magnet?
No, magnetite is a naturally occurring mineral that exhibits magnetic properties due to its composition of iron oxide. It is not an artificial magnet.
What is the chemical composition of magnetite?
The iron itself is usually found in the form of magnetite(Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH).n(H2O)) or siderite (FeCO3). Source:Wiki
Why is cumberlandite magnetic?
Cumberlandite is magnetic due to the presence of magnetite, an iron oxide mineral, in its composition. Magnetite has magnetic properties that make cumberlandite attracted to magnetic fields.
What percent of magnetite is left in the world?
It is estimated that about 1-2% of the total worldwide reserves of magnetite remain. However, this can vary based on factors such as extraction rates and new discoveries.
Why is oxygen 21 percent and nitrogen 78 percent?
This is the composition of the air.
What is the percent composition of oxygen in the magnetite Fe3O4?
The molar mass of Fe3O4 is 231.55 g/mol. The molar mass of oxygen is 16.00 g/mol. There are 12 oxygen atoms in Fe3O4, so the total mass of oxygen in Fe3O4 is 192.00 g. Therefore, the percent composition of oxygen in Fe3O4 is (192.00 g / 231.55 g) x 100 = 82.97%.
How would you determine the chemical composition of magnetite?
Fe2O3

What is the chemical composition of skarn?
Skarns are typically composed of minerals such as garnet, pyroxene, amphibole, epidote, and scapolite. They can also contain sulfide minerals like pyrite, chalcopyrite, and sphalerite, as well as carbonate minerals like calcite and dolomite. The exact chemical composition of a skarn can vary depending on the specific parent rock and the alteration processes that have occurred.
What is the percent composition of Li in LiOH?
The molar mass of LiOH is 23.95 g/mol for Li, 15.999 g/mol for O, and 1.008 g/mol for H. The molar mass of LiOH is 23.95 + 15.999 + 1.008 = 40.957 g/mol. Therefore, the percent composition of Li in LiOH is (23.95/40.957) x 100 = 58.44%.
What is the percent composition of ammonium carbonate?
Ammonium carbonate has the formula (NH4)2CO3. To calculate the percent composition, you first find the molar mass of each element and then divide the molar mass of each element in the formula by the formula mass of the compound and multiply by 100 to get the percentage.
Which is the richest iron ore?
Magnetite - It is an Oxide of Iron and yields 72 percent metal.
What percent of magnetite is left in the world?
It is estimated that about 1-2% of the total worldwide reserves of magnetite remain. However, this can vary based on factors such as extraction rates and new discoveries.
The magnetic iron oxide mineral is called?
Magnetite is the magnetic iron oxide mineral. It is a black or brown mineral with a chemical formula Fe3O4, and it is a common iron ore mineral found in many rocks and soils around the world. It is known for its strong magnetic properties.
What is the percent composition in lithium and bromine?
The percent composition of lithium in lithium bromide (LiBr) is approximately 7.7%. The percent composition of bromine in lithium bromide is approximately 92.3%.
What is the percent composition of CH3CH2OH?
The percent composition of CH3CH2OH (ethanol) is as follows: Carbon (C): (2 * 12.01 g/mol) / 46.07 g/mol x 100 = 52.20% Hydrogen (H): (6 * 1.01 g/mol) / 46.07 g/mol x 100 = 13.09% Oxygen (O): 16.00 g/mol / 46.07 g/mol x 100 = 34.71% Therefore, ethanol is composed of 52.20% carbon, 13.09% hydrogen, and 34.71% oxygen.
