Question

A sample of iron (II III) oxide has 24 iron atoms . How many oxygen atoms does the sample have.​

Answer 1

Explanation:

Note that the number of atoms of each element is the same on each side of the reaction: four iron atoms and six oxygen atoms.

Answer 2

When iron reacts with oxygen it forms iron oxide compound which has a formula of Fe₂O₃.

Oxygen atoms does the sample have 3 atoms

Explanation:

• A sample of iron (II III) oxide has 24 iron atoms it forms cation with a charge of +3 by losing 3 electrons.
• Oxygen gains 2 electrons to form an anion with -2 charge.
• Reaction will be as follows  4Fe+3O₂→2Fe₂O₃
