Question

Beneath each word equation, write and balance the formula equation. Rememberthat several elements exist as diatomic molecules. Dinitrogen pentaoxide -> nitrogen +oxygen

Answer 1

Dinitrogen pentaoxide ===> nitrogen + oxygen

Dinitrogen pentaoxide = N2O5

Nitrogen (remember diatomic) = N2

Oxygen (remember diatomic) = O2

The reaction:

N2O5 ===> N2 + O2

To balance, we must have the same number of atoms on both sides.

So, you must add some numbers in front of each molecule.

Answer: 2 N2O5 ===> 2 N2 + 5 O2 (the balanced reaction)
