Which term refers to the formation of ions as a result of a chemical reaction?

dissociation
electrolyte
hydration
ionization

Option (d) is the correct answer.

Explanation:

A process in which a compound in a chemical reaction results in the formation of ions is known as ionization.

Whereas dissociation is a process in which a compound  divides into atoms, ions or radicals.

A chemical compound which when dissolved in a solution forms ions and thus, conducts electricity is known as electrolyte.

A chemical reaction in which a compound reacts or combines with water is known as hydration.

Therefore, we can conclude that ionization is the term which refers to the formation of ions as a result of a chemical reaction.

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)

explanation:

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
