Iron can be separated with an (electro)magnet.
A substance that cannot be separated physically is a pure substance.
Element.
A compound, such as water (H2O), cannot be physically separated into its component elements (hydrogen and oxygen) but can be chemically separated through a chemical reaction, such as electrolysis, which breaks the bonds between the elements.
To produce 550 g of Fe, you would need the same amount of Al based on the balanced chemical equation of the reaction between Al and Fe. The molar ratio between Al and Fe is 2:3. Therefore, you would need (2/3) * 550 g of Al, which is approximately 367 g.
If a substance can be physically separated into its components, it is a mixture, not a pure substance. A pure substance consists of only one type of particle and cannot be separated into other substances by physical means.

Al is more elastic because it's of light weight than Fe and has lo tensile strength than Fe

This is a solution
The balanced equation is 3 Fe3O4 + 8 Al -> 4 Al2O3 + 9 Fe. Therefore, the coefficient of Fe is 9.

A compound.
10 g of Fe has more atoms because iron has a lower atomic mass than aluminum. This means that there are more atoms in 10 g of Fe compared to 10 g of Al.
