In iron(III) oxide (Fe2O3), there are two iron atoms per molecule. Since the atomic weight of iron is approximately 55.85 g/mol, the total weight of iron in one mole of Fe2O3 would be around 111.7 g.
To calculate the amount of iron present in 4.06 g of iron(III) oxide, you need to consider the molar mass of iron(III) oxide (Fe2O3), which is 159.69 g/mol. The molar mass of iron (Fe) is 55.85 g/mol. There are 2 iron atoms in one molecule of iron(III) oxide. The calculation would be: (2*55.85)/159.69 * 4.06 g = 1.41 g of iron.
Steel typically contains about 0.2 to 2.1 of iron.
Aluminum is not used as the reducing agent in iron extraction because it has a higher reduction potential than iron, meaning it is not able to reduce iron oxide to elemental iron. Carbon, on the other hand, has a lower reduction potential than iron and is commonly used as the reducing agent in the extraction of iron.
Most iron ores are iron oxides or iron sulfides. Iron ores are also usually hydrated (i.e. includes water of crystallization). A variety of other metal ores (e.g. copper, zinc, lead) are sometimes mixed with iron ores. In much lower concentrations, almost any element (except the inert gases) might be found.
Yes, nitric acid can dissolve iron oxide through a chemical reaction that involves converting the iron oxide into soluble iron nitrate. This process is known as dissolution or chemical etching. However, the reaction may take time and may require the acid to be heated or used in concentrated form.

The oxide Fe2O3 has: 70 % iron and 30 % oxygen.
too much oxygen combines with the raw iron and forms iron oxide or rust. this weakens the iron and thus damages it.
its an iron catalyst (iron oxide)
If it is pure iron then by definition there is no carbon or anything else present in it, just iron.
Steel typically contains about 0.2 to 2.1 of iron.
Pure iron oxide is a compound, but if there is something else mixed in with it, then of course it will become a mixture. There is more than one oxide of iron, though. Here are 2 types of iron oxide: Iron (II) Oxide is a black powder with a formula of FeO Iron (III) Oxide, also rust, is a brownish-red powder with a formula of Fe2O3
In a 5g suppository with 5% zinc oxide, the amount of zinc oxide present is 5% of 5g, which is 0.25g (or 250mg) of zinc oxide.
The amount of iron in sand can vary depending on the specific composition of the sand. On average, sand is composed of about 3-5% iron as iron oxide minerals like magnetite or hematite. This means that in a kilogram of sand, there could be around 30-50 grams of iron present. However, it's important to note that this is a rough estimate and the actual iron content can differ based on the source of the sand.
Lead won't rust in the same way as iron, a white oxide layer will appear overtime, but it won't break away as much as rust on iron.
When iron is burnt, it combines with oxygen to form iron oxide (rust). This increase in weight is due to the added oxygen atoms bonded to the iron atoms, making the total weight of the iron and oxygen combined greater than that of the unburnt iron alone.
Amethyst is mainly composed of silicon dioxide, or quartz, with trace amounts of iron that give it its purple color. The purple hue can vary, depending on the amount of iron present during its formation.
