The answer for the following question is explained below.

The option for the following answer is "d".

Explanation:

The phlogiston theory of combustion:(Greek word phlogiston means "BURN")

Phlogiston theory states that phlogisticated substances are the substances that contain phlogiston and dephlogisticate when burned.

Dephlogisticating is the process of releasing stored phlogiston,which is absorbed by the air.

Growing plants then absorb this phlogiston,which is why air does not spontaneously combust and also plant matte burns as well as it does.

The prevailing theory was that flammable materials contained a substance called phlogiston that was released during the combustion.

For example:

phlogiston was transferring into the surrounding air.

The acid HOCl (hypochlorous acid) is produced by bubbling chlorine gas through a suspension of solid mercury(II) oxide particles

Answer: The expression for equilibrium constant is $K_{eq}=\frac{[HOCl]^2}{[H_2O][Cl_2]^2}$

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as $K_{eq}$

For the general chemical equation:

$aA+bB\rightleftharpoons cC+dD$

The expression for $K_c$ is given as:

$K_c=\frac{[C]^c[D]^d}{[A]^a[B]^b}$

For the given chemical reaction:

$2HgO(s)+H_2O(l)+2Cl_2(g)\rightleftharpoons 2HOCl(aq.)+HgO.HgCl_2(s)$

The expression for $K_{eq}$ is given as:

$K_{eq}=\frac{[HOCl]^2[HgO.HgCl_2]}{[HgO]^2[H_2O][Cl_2]^2}$

The concentration of solid is taken to be 0.

So, the expression for $K_{eq}$ is given as:

$K_{eq}=\frac{[HOCl]^2}{[H_2O][Cl_2]^2}$
