What are three ways to increase the rate of dissociation of a solid

Three ways to increase the rate of dissociation of a solid are:

1. Increasing the surface area of the solute.

2. Increasing the temperature of the solvent.

3. Agitating the solute and solvent mixture.

Explanation:

The dissociation of a solid is defined as the separation of ions when an ionic compounds dissolve. The dissociation rate can be increased by increasing the surface area of the solute because it would get enough  chance to interact with other particles, hence the rate of dissociation increases.

By increasing the temperature, the kinetic energy of the molecules increase thereby dissolving more of the solute particles.

Agitating affects dissociation rate because it helps solute particle to get distributed evenly and hence gets dissociate easily.

the grams   of   barium that   are in   2.3 x 10^23   atoms of barium   is   52.4 g (answer c)

    calculation

mass = moles   of ba   x molar   mass of ba

  molar mass of ba from periodic table=   137.3 g/mol

  use the   avogadro's law   constant   to   calculate the moles of barium

  that   is     1 mole =   6.02   x 10^23 atoms

                    ? moles = 2.3 x 10^23   atoms

by cross   multiplication

=(1 mole   x 2.3x 10^23 atoms)   / 6.02   x10^23 atoms)=   0.382   moles

mass   is therefore = 137.3   g/mol x 0.382 mol = 52.4 ( answer c)
