Complete and balance the molecular equation for the reaction of aqueous ammonium bromide, nh4br , and aqueous lead(ii) acetate, pb(c2h3o2)2 . include physical states. molecular equation: nh_{4}br(aq) + pb(c_{2}h_{3}o_{2})_{2}(aq) -> nh4br(aq)+pb(c2h3o2)2(aq)⟶

Answer : The complete balanced molecular equation will be,

Explanation :

Balanced chemical equation : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The complete balanced molecular equation will be,

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
