The definition of oxidation is loss of electrons. The definition is formation of additional bonds between carbon and oxygen (or in the number of carbon-hydrogen bonds.) These are similar because when forms a bond with electronegative , it essentially some of its attraction for its electrons.

Oxidation can be defined in many ways:

In terms of electron, Oxidation can be defined as loss of electrons by an atom or ion or a molecule during a reaction.

In terms of oxygen transfer, oxidation maybe defined as a substance that gains oxygen or loses hydrogen.

It can also be defined as a process in which a carbon atom gains bond to more electronegative atom such as oxygen.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
