How many iron atoms are reactants in this equation? 4Fe+ 302
1 answer:
Answer:
4 atoms of oxygen.
Explanation:
The given equation is :
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.
