An aqueous solution of sodium sulfide is allowed to react with an aqueous solution of magnesium chloride.

olya-2409 [2.1K]

Answer : The correct option is, (b) $2Na^+$

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,

$Na_2S(aq)+MgCl_2(aq)\rightarrow 2NaCl(aq)+MgS(s)$

The complete ionic equation in separated aqueous solution will be,

$2Na^+(aq)+S^{2-}(aq)+Mg^{2+}(aq)+2Cl^{-}(aq)\rightarrow 2Na^+(aq)+2Cl^{-}(aq)+MgS(s)$

In this equation the species $Na^+\text{ and }Cl^{-}$ are the spectator ions.

Hence, the complete ionic equation contains specie is $2Na^+$

Which of the following leads to a higher rate of effusion?

Basile [38]

Answer:

b. Lower molar mass.

Explanation:

Thomas Graham found that, at a constant temperature and pressure the rates of effusion of various gases are inversely proportional to the square root of their masses.

∨ ∝ 1/√M.

where, ∨ is the rate of diffusion of the gas.

M is the molar mass of the gas.

As the gas has a lower molar mass, it will have a higher rate of effusion.
