The oxidation number is 0. The sum of all oxidation number in a molecule that has not charge is always 0. If it has a charge (ion negative or positive) then the sum must be equal to the charge number.

What is oxidation number for Na in NaOH?
The oxidation number is +1. (Oxidation number for an ion is the ionic charge)
What is the oxidation number of SO2?
Oxidation state of O is -2.Oxidation state of S is +4.
Oxidation number of Cr in CrO5?
6. This is because it is a peroxide, with a structure Cr(O)(O2)2, where the nominal ligands are O2- (-2 ox.number in oxides) and O22- (-1 ox.number in peroxides) which gives the Cr an oxidation number of +6. It is sometimes called Chromium(VI) oxide peroxide.
What is the oxidation number of titanium?
The oxidation number of any element by itself is 0.
What is the oxidation number of oxygen in O2PtF6?
The structure of O2PtF6 is known and there is an O2 unit. The O2 is best formulated as O2+ ( dioxygenyl) and the oxidation number of each O atom is +1/2. (+0.5). This is an interesting compound PtF6 is a very stong oxidising agent.
What is the oxidation number for element O?
The oxidation number of O in any elemental form (e.g. O2, O3) is zero. Typically in chemical compounds the oxidation number of O is -2 (oxide ion)
What is oxidation number for Na in NaOH?
The oxidation number is +1. (Oxidation number for an ion is the ionic charge)
What is the oxidation number of SO2?
Oxidation state of O is -2.Oxidation state of S is +4.

Does Oxygen have the same oxidation number in ozone O3 and in oxygen O2?
no, one O does have -2 and the others each +1
What is the oxidation number of Ru O 4?
Ru has oxidation number +8, O has oxidation number of -2
What is the oxidation number of O in O22-?
The overall oxidation number is -2 so the average oxidation number of O is -1.
What is the oxidation number for CL in CLO3?
Oxidation number of chlorine is +7. oxidation number of O is -2.
What kind of reaction is 2H2O2 2H2O plus O2?
2H2O2 <-> H2O + O2 the oxidation number of each O in H2O2 is -1 the oxidation number in H2O is -2 the oxidation number in O2 is zero. The average oxidation number of oxygen atoms on both sides of the equation. is the same. So overall the net change to oxygen is zero one is reduced two are oxidised. Looked at from the viewpoint of the oxygen atoms in O2 they started off with oxidation number of -1 and have ended up with 0, so they have been oxidised. (oxidation is loss of electrons, and therefore an increase in oxidation number.)
What is the oxidation number of H2O2?
The oxidation number for H is +1, and the oxidation number for O is -1.
