To balance the equation N₂ + O₂ ➡ N₂O₅, we need to ensure that the number of each element is the same on both sides of the equation.
To balance the nitrogen (N) atoms, we need to put a coefficient of 2 in front of N₂O₅, making it 2N₂O₅.
Now, let's balance the oxygen (O) atoms. On the left side, we have 2 oxygen atoms from O₂, and on the right side, we have 5 oxygen atoms from N₂O₅. To balance them, we need to put a coefficient of 5/2 in front of O₂, making it 5/2O₂.
The balanced equation is: 2N₂ + 5/2O₂ ➡ 2N₂O₅.
