Which of the following is property of salts •undergo combustion •do not make iconic bonds easily •do not conduct electricity as solids •formed due to reaction of acid with water

Option (c) is the correct answer.

Explanation:

For a compound to conduct electricity, it is necessary that it should be present in molten state that is, there should be ions.

For example, a solution of NaCl is able to conduct electricity because it contains sodium ions and chlorine ions.

But a salt present in solid state is not able to conduct electricity because molecules are not present in ionic form. When this solid is dissolved in water then its molecules convert into ions and only then it will be able to conduct electricity.

Thus, we can conclude that salts do not conduct electricity as solids is property of salts.

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)
