How to find the Oxidation Number for O in Na2O2 (Sodium peroxide)
To find the correct oxidation state of O in Na2O2 (Sodium peroxide), and each element in the molecule, we use a few rules and some simple math. First, since the Na2O2 molecule doesn’t have an overall charge (like NO3- or H3O+) we could say that the total of the oxidation numbers for Na2O2 will be zero since it is a neutral molecule. We write ...

Did you know that the reaction of sodium with water is one of the most exciting chemical reactions? comm_to_physics When you add a piece of sodium to water, a rapid and violent reaction occurs, as sodium (Na) reacts with water molecules (H₂O) to form sodium hydroxide (NaOH) and hydrogen gas (H₂). Chemical equation: 2Na 2H2O 2NaOH H2↑ Results: 1. Hydrogen gas production: Gas bubbles appear that cause small explosions. 2. Extreme heat: The reaction releases heat, which can ignite the gas formed. ▲
