Oxidization and reduction

Question 1

define oxidization in classical concept

Answer 1

the chemical process which involves combination of oxygen or any electronegative atom or removal of hydrogen or any electropositive atom

Question 2

define oxidization in electronic concept

Answer 2

a reaction in which one or more electrons is lost, by atom, ion or molecule.

Question 3

define oxidization number

Answer 3

the residual charge which an atom appears to have when all other atoms are removed as ions from the molecules

Question 4

what is the oxidization number of alkali metal (na, li, k,)

Answer 4

+1

Question 5

what is the oxidization number of halogens (f, cl, br)

Answer 5

-1

Question 6

what is the oxidization number of oxygen and hydrogen

Answer 6

oxygen= -2 
hydrogen= +1

Question 7

what is the oxidization number of oxygen in peroxides(o2)?

Answer 7

-1

Question 8

list the steps of balancing the reaction through oxidation number

Answer 8

1. count the oxidation number of each reactants and products
2. calculate the change in the oxidation numbers from reactants to products
3. Crisscross the change in the oxidation number
4. balance the atoms
5. balance the H and O atoms

Question 9

list the steps of balancing the reox reactions by ion electron method

Answer 9

1. split redox reaction into oxidation half and reduction half
2. balance all elements except H and O, balance O using H2O, balance H using using H+, Balance the charge using electrons
