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 ...

Na2O Reaction with Water
5.9K views · 157 reactions | Reaction of sodium with water Sodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and hydrogen gas (H2). The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic. During the reaction, the sodium metal may well become so hot that it catches fire and burns with a characteristic orange colour. 2Na(s) + 2H2O → 2NaOH(aq) + H2(g) | ChemClub | Facebook
