At a certain temperature, the for the decomposition of h2s is 0.776. h2s(g)↽−−⇀h2(g)+s(g) initially, only h2s is present at a pressure of 0.200 atm in a closed container. what is the total pressure in the container at equilibrium?

0.365 atm is the total pressure in the container at equilibrium.

Explanation:

Given , equilibrium constant of the reaction in terms of partial pressure:

Initial Partial pressure of the hydrogen sulfide gas =

Let the partial pressure of hydrogen gas and sulfur gas at equilibrium be p.

Initially   0.200 atm

At eq'm  0.200-p           p   p

Solving the equation we will get two values of 'p' from which we will ignore the negative value.

p = 0.165 atm

Partial pressure of the hydrogen sulfide gas at equilibrium=

Total pressure in the container at equilibrium :

0.200-p + p + p =0.200 atm +p = 0.365 atm

passing a magnet thought the

mixture , because iron gets attracted to magnet .

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
