14. oxidation number in Co in LiCoO2
Answer: The oxidation number of Co is 3
Explanation: because O is -2 then Li is +1 if you will solve it it would look like this:
Li+Co+2(O)=0
1+Co+2(-2)=0
1+Co+-4=0
Co+-3=0
Co=3
15. oxidation number of calcium
Answer:
+1
Explanation:
the oxidation number of an atom is the charge that atom would have if the compound was composed of ions. 1. ... The oxidation number of simple ions is equal to the charge on the ion. The oxidation number of sodium in the Na+ ion is +1, for example, and the oxidation number of chlorine in the Cl- ion is -1.

20. sulfur oxidation number?
Answer:
Sulphur exhibits oxidation numbers of -2, 0, +2, +4 and +6. Oxidation number -2 is seen in the sulphide ion, S--, and a typical compound is H2S, hydrogen sulphide or hydrosulphuric acid.21. what is the oxidation number of NO2
Answer:
+4
Explanation:
Oxidation states of nitrogen
Ox. state Species
+5 NO3
- Nitrate ion, oxidizing agent in acidic solution.
+4 NO2 Nitrogen dioxide, a brown gas usually produced by the reaction of concentrated
nitric acid with many metals. It dimerizes to form N2O4.
+3 NO2
- Nitrite ion in basic solution and nitrous acid in acidic solution. Can be either an
oxidizing agent to usually produce NO(g) or a reducing agent to form the nitrate
ion.
+2 NO Nitrogen oxide also called nitric oxide. A colorless gas produced by the reaction
of metals with dilute nitric acid which then reacts with O2 in the air to form the
brown NO2 gas.
+1 N2O Dinitrogen oxide also called nitrous oxide or laughing gas.
0 N2 Commonly found in air and vry unreactive because of the very strong triple bond.
-1 NH2OH Hydroxylamine, a weak base, which can act as either an oxidizing agent or
reducing agent.
-2 N2H4 Hydrazine, a colorless liquid, is a weak bse. Used as a rocket fuel. It
disproportionates to N2 and NH3.
-3 NH3 In basic solution and as NH4
+ in acidic solution. Not genrally used as a reducing
agent in aqueous solutions. When ammonia is burned in the presence of oxygen it
is oxidized to either N2 or NO. The oxidation of ammonium salts usually
produces nitrogen gas.

24. oxidation number of S
Answer:
-2
Explanation:
The sulphur has an oxidation state of -2. Oxidation state shows the total number of electrons which have been removed from an element (a positive oxidation state) or added to an element (a negative oxidation state) to get to its present state.
Answer:
The answer is -2

25. The oxidation number of a species increases when it undergoes oxidation.
Answer:
true
Explanation:
A loss of negatively-charged electrons corresponds to an increase in oxidation number, while a gain of electrons corresponds to a decrease in oxidation number. Therefore, the element or ion that is oxidized undergoes an increase in oxidation number.

28. What is the oxidation number of phosphorus in each of the following oxides?
Answer:
i hope it help
Explanation:
Explanation:
You're dealing with an ion, the phosphate anion to be precise, which means that the oxidation states of each atom must add up to give the overall charge of the ion.
So, start by writing down what you know. You know that
the ion has a (3-) overall charge
the ion is made up of one phosphous atom and four oxygen atoms
oxygen's oxidation state in most compounds is −2.
This means that you can write
one phosphorus atom1×ONP+4×ONoxygenfour oxygen atoms=−3
Solve the equation for ONP to get
ONP+4×(−2)=−3
ONP=−3+8=+5
So, phosphorus has a +5 oxidation state in the phosphate anion, PO3−4.
29. What is the oxidation number of H2O2?
Answer:
-1
Explanation:
Because oxygen has a higher electronegativity than hydrogen, the shared electrons are closer to the oxygen atom than to the hydrogen atom. This is not the total transfer of electrons that would create an ion, but partial charges do form—the hydrogen end of the bond is partially positive (+1) because it has partially lost one electron, and the oxygen end of the H–O is partially negative (-1) because it has partially gained the one electron from hydrogen
Answer:The oxidation number of H is +1 For two H atoms, the sum is +2. H2O2 has no charge, the total oxidation number of the two O atoms must be -2. The oxidation number of one oxygen atom must be -1.
