What is the molar concentration of potassium ions in a 0.250 m k2so4 solution?

Answer : The molar concentration of ion is, 0.5 M

Explanation :

The dissociation reaction of is,

By the stoichiometry we can say that, 1 mole of dissociates into 2 mole of ions and 1 mole of ions.

As we  are given the concentration of is, 0.250 M.

So, the molar concentration of ion =

The molar concentration of ion = 0.250 M

Therefore, the molar concentration of ion is, 0.5 M

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
