Aqueous solutions of hydrogen peroxide sold in pharmacies are usually approximately 3% H2O2 by mass. However, in solution, hydrogen peroxide decomposes into water and oxygen. What is the percent by mass of a solution of hydrogen peroxide, H2O2, prepared from 2.104 g of H2O2 which is titrated with 51.78 cm3 of 0.03245 mol dm-3 KMnO4(aq). The reaction occurs in an acidified solution

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

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
