Given the balanced ionic equation representing a reaction: Cu(s) + 2Ag+(aq) Cu2+(aq) + 2Ag(s) During this reaction, electrons are transferred from *

A redox reaction equation is one in which a specie looses electrons and another specie gains electrons.

Redox reaction is a give and take process. One chemical specie loose electrons to be accepted by another chemical specie.

In this case, copper looses electrons as follows;

Silver gains electrons as follows;

Overall redox balanced ionic equation;

We can see from the overall equation that electrons are transferred from copper to silver.

During this reaction electron is transfer from copper to silver.

Explanation:

Ionic equation:

Cu + 2Ag⁺      →    Cu²⁺ + 2Ag

Given equation shows that the silver on left hand side is present in the form of cation. The charge on silver is +1 it means one electron is lost by one silver atom. While copper is present in neutral form with oxidation state zero.

Thus copper lose two electron and gain +2 charge these two electrons are accepted by two silver atoms and became neutral.

This equation shows the redox reaction.

Silver gets reduced by gaining the electron and copper gets oxidized by losing the electrons.

Oxidation:

Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.

Reduction:

Reduction involve the gain of electron and oxidation number is decreased.

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:

the answer is d : ) have a good da
