Question

Na + O₂ → Na₂O
How do I balance it out

Answer 1

4 Na + O₂ → 2 Na₂O

Step-by-step explanation:

To balance the chemical reaction equation...

Na + O₂ → Na₂O

First, we need to match the number of oxygens on each side by adding a coefficient of 2 to Na₂O:

__Na + O₂ → 2 Na₂O

Then, we need to match the number of sodiums on the left side with those on the right side by adding a coefficient of 4 to Na:

4 Na + O₂ → 2 Na₂O
