None of the above. Oxygen is an element, while acids and bases are compounds of more than one element. The degree of acidity or alkalinity is given as pH, which is a measure of the Hydrogen ion concentration in the solution. Oxygen by itself, being an element, has no hydrogen ion concentration, so is none of those things. Neither, in that context of pH, is it neutral.
The peroxide ion is a base.
Hydrogen peroxide (which is often simply called peroxide) is a very weak acid.
Oxygen is present in many acids and many bases.
O2- is a brönsted lowry base because it can accept a proton to become OH.

Example [OH-]acid (!) conjugated with [O2-]baseor else, in water: [H2O]acid (!) conjugated with [OH-]base
O2 denotes oxygen. It is element. It is not an acid.
This is an oxidation reaction of N from -3 (in NH3) to +2 (in NO) oxidation value. 4 NH3 + 5 O2 --> 6 H2O + 4 NO
1. The thermal decomposition of calcium carbonate (if you think to this reaction) is not an acid-base reaction. 2 The calcium oxide is not oxidized by oxygen.
An acid can turn into a base if you mix a much stronger base with it! That way the base acid overpowers the acid and makes the acid a base!

O2-
Neither. Strictly speaking it is a very weak base. A Magnesium Nitrate solution is neutral with a pH of 7.0. Salts of strong acids are neutral. Magnesium Nitrate is salt of Nitric acid which is very strong acid.
There is no conjugate) base coupled to bromide, Br-, because this Br- can NOT donate (by protolysing) a proton (H+) in water.However Br- itself is the very, very weakest base of the (very, very) strong conjugate acid HBr.This is the only possible conjugate acid/base pair:HBr/Br-
Flour is a base, not an acid.
If there is any acid radical present, it is one with the formula O2-2. However, hydrogen peroxide is not usually considered an acid except by the broadest definition(s) of acid behavior.
