H - +1 (oxidation number) O - -2 (oxidation number) 2*(+1)+(-2)=0 H2O is neutral (if that's what you want)
There is no carbon in H2O (water) molecule
-2
For the hydrogen atoms the oxidation state is 1+, for the oxygen it is 2-
H in H20 is Hydrogen
Water, or H2O is a free-standing neutral compound, so it's oxidation number is 0. Its atoms have oxidation number though. Hydrogen's oxidation number in water is +1, and oxygen's is -2.
-2 for O and +1 for H
+1 h2o---> 2h + -2 = 0; 2h = +2; h = +1
H2O. +1 for each H, -2 for O.
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.)
Zero
O.S. of H = +1 O.S. of O = -2 O.N. of cpd = 0
As nearly always with oxygen, it is - 2.
When H2O2 acts as an oxidizing agent, the H2O2 must be reduced. Therefore, the product from it will be water, in which oxygen has an oxidation number of -2, whereas in H2O2 has an oxidation number of -1 and in O2 the oxygen has an oxidation number of 0.

O2 + 2 H2 -> 2 H2O reduction reaction is every reaction during which the oxidation number of any atom is lowered. In this case, O2 has its oxidation number changed from 0 to -2.
oxidation number of I is -1. oxidation number of F is +1.
non metal oxides react with water to give oxyacid but also do undergo disproponation depending on the oxidation number ( oxidation number is increased and decreased, respectively) of the metal N2O5 + H2O → 2HNO3 3NO2 + H2O → 2HNO3 + NO
Oxidation number of K is +1. oxidation number of N is -3. oxidation number of O is -2.
Sodium's oxidation number is +1.Nitrogens oxidation number is +3. Oxygen's oxidation number is -2.
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
Potassium's oxidation number is +1. Chromium's oxidation number is +6. Oxygen's oxidation number is -2.
Oxidation number of K is 1+Oxidation number of N is 3+ Oxidation number of O is 2-
It is equal to the charge. Fluorine's oxidation number is -1.In an ion, the oxidation number is equal to its charge. Fluoride has oxidation number -1. It is the lowest oxidation number that fluorine can take.
There is no oxidation number for compounds. The oxidation number for the calcium in CaSO4 is 2+, the oxidation number for oxygen is 2-, and the oxidation number for sulfur is 6+.
