Which statement is true of the following reaction? Upper H subscript 2 plus upper O subscript 2 right arrow upper 2 H superscript plus, plus upper O superscript 2 minus.
It is balanced for oxidation state and for number of atoms.
It is not balanced for oxidation state or for number of atoms.
It is not balanced for oxidation state but is balanced for number of atoms.
It is balanced for oxidation state but is not balanced for number of atoms.

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

the answer is true. hope it .
