I want a balanced chemical equation for iron+oxygen=iron oxide please

To balance the chemical equation for the reaction between iron and oxygen to form iron oxide (Fe + O2 → Fe2O3), we need to ensure that the number of atoms of each element is equal on both sides of the equation. Here's a step-by-step explanation of how to balance the equation:

1. Begin by writing the unbalanced equation:
Fe + O2 → Fe2O3

2. Count the number of atoms of each element on both sides of the equation and make a note of them:
On the left side: 1 Fe, 2 O
On the right side: 2 Fe, 3 O

3. Start by balancing the atoms of the most complex compound, which in this case is Fe2O3. Since there are already two Fe atoms on the right side, we can balance the oxygen atoms first.
Fe + O2 → 2 Fe + ...

4. To balance the oxygen atoms, multiply the O2 molecule on the left side by 3 (to get 6 oxygen atoms) to match the 6 oxygen atoms in Fe2O3 on the right side:
Fe + 3 O2 → 2 Fe + ...

5. Now, with the oxygen atoms balanced, count the number of Fe atoms on each side:
On the left side: 1 Fe
On the right side: 2 Fe

6. To balance the Fe atoms, we need to multiply the Fe molecule on the left side by 2:
2 Fe + 3 O2 → 2 Fe + ...

7. Finally, the equation is balanced for Fe and O atoms, but we can see that the right side has more atoms than the left side. To balance this, we need to put a coefficient of 4 in front of the Fe2O3 molecule on the right side:
2 Fe + 3 O2 → 4 Fe2O3

And there you have it – the balanced chemical equation for the reaction between iron and oxygen to form iron oxide is:

2 Fe + 3 O2 → 4 Fe2O3
