Calculate the oxidation number of Fe in Fe3O4?
It has both +3 and +2 oxidation states
How do you calculate the oxidation number of I in HIO2?
+1 for H, -2 for each O, +3 for I
How to calculate the oxidation number of Sb in Sb2O4?
oxygen is 2- so four oxygen have 8- charges therefore two Sb should have 8+ and therefore the oxidation number of Sb is 4+
How do you calculate the the oxidation number of mn in k2mno4?
First O has an oxidation number of -2; K will an oxidation number of +1 as it is an alkali metal. Therfore the Mn is +6. note that while the manganate ion exists, the question may relate to the permanganate ion MnO4-, so KMnO4, where Mn has oxidation number of +7
What determines the oxidation number?
The oxidation number determines how much an element is oxidated, so the oxidation number of...1. elements is always 0.2. of simple ions is always the charge, e.g. in Cu2+ the oxidation number of copper is +2.3. hydrogen is usually +1, oxygen usually -2, alkali metals +1, etc.In molecules without a charge, the sum of the oxidation numbers has to be 0. This way you can calculate the oxidation number of its compounds. For example in KMnO4, the oxidation number of oxygen is -2, of K is +1, so if the sum is zero then the oxidation number of Mn has to be +7.In complex ions (OH-, MnO4-, ...) the sum of the oxidation numbers has to be the charge of the ion. (so in OH- and MnO4- it's -1).

How is an unknown oxidation state of an element within a compoud determined?
In a compound the sum of oxidation states of the elements contained is zero.E1 + E2 + ... = 0If you know the oxidation states of the elements E1... you can calculate the oxidation state of the element E2.
How do you calculate the oxidation number of I in HIO2?
+1 for H, -2 for each O, +3 for I
How can you calculate the oxidation state of fluorine in O2F2?
To calculate the oxidation state of fluorine in O2F2, first draw a diagram of the molecule: F-O-O-F Determine the most electronegative atom(s), which are fluorines -- the most electronegative atom there is. Being in the group 7A, a fluoride ion would gain an electron to a -1 charge, so each has an oxidation number of -1. The oxygens, therefore, have an oxidation number of +1 each.

The oxidation state of CoCO3?
Co = +2 oxidation C = +4 oxidation O = -2 oxidation
What is the oxidation number of c2h4?
Oxidation number is usually defined along the lines of the charge on the central atom if all "ligands" are removed along with the electron pairs.Now C2H4 is H2C=CH2 so we remove H as H- and leave a "charge" on the carbon atoms of 2+. the oxidation number of carbon is therefore (+)2.There is always debate about this term and the closely related term oxidation state. Confusingly some people use the term oxidation number to mean oxidation state.To calculate oxidation state which uses the relative electronegativity to determine which atom "keeps" the electrons, the hydrogens would be treated not as H- but as H+ leaving the carbon in an oxidation state of -2.My advice would be to check your notes and see which definition your teacher is using.
What is the oxidation state of oxygen in H2O2?
O = -2 oxidation state H = +1 oxidation state
What is the oxidation nu?
Oxidation number is oxidation states of an element. It can be positive or negative.
What is the oxidation number of IF?
oxidation number of I is -1. oxidation number of F is +1.
