Answer 1

Answer:

2Fe₂O₃

Explanation:

If the number of atoms of each element are the same on reactant and product sides, it is a balanced equation. This is not a balanced equation because the number of atoms of each element are not the same on reactant and product sides.

To balance an equation, let's first list the atoms:

FeO

Then, we count the number of atoms on both sides:

1 Fe 22 O 3

We multiply the number of atoms for each element on either side by the number of molecules (aka coefficient, or "big number"):

4 Fe 26 O 3

To balance the equation, we need the total number for Fe on the right side to be 4, and the total number for O on the right side to be 6. We can do that by adding a "big number", or coefficient in front, which when multiplied by the number of atoms for each element, makes a balanced equation.

2 is a good value: 2 × 2 = 4, and 2 × 3 = 6.

As such:

4Fe + 3O₂ → 2Fe₂O₃
