Answer 3

The chemical equation you've provided is not balanced. To balance it, you need to make sure that you have the same number of each type of atom on both sides of the equation. Let's balance it step by step:

Fe2O3 + 3H2 → 2Fe + 3H2O

Now, let's balance it:

1. Balance the iron (Fe) atoms: There are 2 Fe atoms on the right side and 2 Fe atoms on the left side, so Fe is already balanced.

2. Balance the hydrogen (H) atoms: There are 6 hydrogen atoms on the left side (3H2), and only 2 on the right side (3H2O). To balance the hydrogen atoms, you can add a coefficient of 3 in front of the H2 on the right side:

   Fe2O3 + 3H2 → 2Fe + 3H2O

3. Balance the oxygen (O) atoms: Now, let's count the oxygen atoms. On the left side, there are 3 oxygen atoms in Fe2O3 and 6 oxygen atoms in 3H2O, for a total of 3 + 6 = 9 oxygen atoms. On the right side, there are 2 oxygen atoms in 2Fe and 6 oxygen atoms in 3H2O, for a total of 2 + 6 = 8 oxygen atoms. To balance the oxygen atoms, you can add a coefficient of 1.5 (which can be expressed as 3/2) in front of the Fe2O3 on the left side:

   1.5Fe2O3 + 3H2 → 2Fe + 3H2O

Now, all the elements are balanced:

On the left side:

• 1.5 Fe2O3 (3 Fe atoms and 4.5 oxygen atoms)
• 3 H2 (6 hydrogen atoms)

On the right side:

• 2 Fe (2 Fe atoms)
• 3 H2O (3 hydrogen atoms and 3 oxygen atoms)

All the atoms are balanced, and the equation is now balanced.
