How can the equation 'Mg + O₂ —> MgO' be balanced?
To balance the oxygen atoms, we need to add a coefficient of 2 in front of the magnesium oxide (MgO) on the right side. This gives us:
Mg + O₂ —> 2MgO
Now there are 2 oxygen atoms on both sides.
To balance the magnesium atoms, we need to add a coefficient of 2 in front of the magnesium (Mg) on the left side. This gives us:
2Mg + O₂ —> 2MgO
Now there are 2 magnesium atoms on both sides.
