Balance the following equation. then determine the ratio for the products kcl and o2 generated during the decomposition of potassium chlorate. kclo3 kcl + o2 1: 1 2: 2 4: 3 2: 3 3: 2

2:3

Explanation: Decomposition reaction is a type of chemical reaction in which one reactant gives two or more than two products.

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

according to the balanced chemical equation, 2 moles of potassium chlortae on decomposition gives 2 moles of and 3 moles of .

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
