Question

How many iron atoms are reactants in this equation? 4Fe+ 302

2Fe20
Select one:
3
0
2
4

Answer 1

4 atoms of oxygen.

Step-by-step explanation:

The given equation is :

`4Fe+3O_2\rightarrow 2Fe_2O_3`

Here Fe and O₂ are reactants and Fe₂O₃ is a product. It is a balanced chemical reaction in which the number of atoms on LHS are equal to number of atoms on RHS.

4 atoms of iron react with 3 atoms of oxygen to form iron oxide. Hence, there are 4 atoms of reactants in this equation.
