What is the charge of Fe in Fe2O3?
The charge of Fe in Fe2O3 is +3. Iron (Fe) typically forms a +3 charge in ionic compounds like Fe2O3.
The formula for rust can be represented by Fe2O3 How many moles of Fe are present in 14.2 g of the compound?
To find the number of moles of Fe in 14.2 g of Fe2O3, we need to use the molar mass of Fe2O3 (molecular weight = 159.69 g/mol) and the ratio of Fe to Fe2O3. There are 2 moles of Fe in 1 mole of Fe2O3, so we find the moles of Fe in 14.2 g of Fe2O3 by: (14.2 g / 159.69 g/mol) * 2 = 0.249 moles of Fe.
What mole ratio would you use to determine moles Fe if moles Fe2O3 is known?
If the moles of Fe2O3 are known, you would use the mole ratio from the balanced chemical equation for the reaction involving Fe2O3 and Fe. In the balanced equation, the mole ratio between Fe2O3 and Fe is 2:2, which simplifies to 1:1. This means that for every mole of Fe2O3, there is an equivalent mole of Fe.
When the equation Fe2O3 Al ----- Al2O3 Fe is correctly balanced what is the coefficient of Fe?
The balanced equation is 2Fe2O3 + 4Al ----> 2Al2O3 + 3Fe. The coefficient of Fe is 3.
Iron III oxide is formed when iron combines with oxygen in the air How many grams of Fe2O3 are formed when 16.7 g of Fe reacts completely with oxygen?
To determine the mass of Fe2O3 formed, you need to first find the molar mass of Fe and Fe2O3. Then, use stoichiometry to calculate the mass of Fe2O3 that can be produced from 16.7 g of Fe. The balanced equation is 4Fe + 3O2 → 2Fe2O3, which shows that 4 mol of Fe produces 2 mol of Fe2O3. By converting 16.7 g of Fe to moles, you can then use the mole ratio to find the grams of Fe2O3 formed.
What is the charge of Fe in Fe2O3?

How do you calculate the Fe content in FeO and Fe2O3?
To calculate the Fe content in FeO, you need to consider that Fe accounts for about 71.85% of the FeO compound's molecular weight. For Fe2O3, each Fe atom accounts for about 69.94% of the compound's molecular weight. After determining the molecular weight of FeO and Fe2O3, you can find the Fe content by multiplying the molecular weight of Fe by the appropriate percentage.
