An aqueous solution of sodium sulfide is allowed to react with an aqueous solution of magnesium chloride.
The complete ionic equation contains which of the following species (when balanced in standard form)?

a.
Cl-(aq)

b.
2Na+(aq)

c.
2S2-(aq)

d.
Na+(aq)

e.
3Mg2+(aq)

Answer : The correct option is, (b)

Explanation :

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The balanced molecular equation will be,

The complete ionic equation in separated aqueous solution will be,

In this equation the species are the spectator ions.

Hence, the complete ionic equation contains specie is

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
