How many elements are in 2Fe2O3?
In 2Fe2O3, there are 2 iron (Fe) atoms and 3 oxygen (O) atoms, giving a total of 5 atoms.
What shows how many atoms of each element are in a unit of substance?
The chemical formula shows you this. The subscripted number next to each element shows how many atoms are present in a molecule or formula unit. If no number is shown, then only one atom of that element is present.
How many oxygen atoms are present in the reactant side of the chemical equation 4Fe 3O2 2Fe2O3?
4Fe + 3O2 --------> 2Fe2O3 so there are 3 oxygen molecule reacatnts and thus 6 oxygen atoms in the reactants.
How can you tell how many atoms of each element there are?
You can determine the number of atoms of each element in a compound by using the chemical formula of the compound. The subscripts in the formula indicate the number of atoms of each element. For example, in H2O (water), there are 2 hydrogen atoms and 1 oxygen atom.
