A reaction mixture initially contains 2.8 M H2O and 2.6 M SO2. Determine the equilibriumconcentration of H2S if Kc for the reaction at this temperature is 1.3 × 10-6.

x = 0.115M

Explanation:

Kc = [H2S]²*[O2]³ / [H2O]²*[SO2]²

Let x be the moles of H2S formed. Each mole of H2S takes one each mole of H2O and SO2 so after the reactions

[H2O] = 2.8 - x and [SO2] = 2.6 - x also for each mole of H2S, 1.5 moles of O2 are formed, so [O2] = 1.5*x

Kc = x²*(1.5*x)³ / (2.8 - x)²*(2.6 - x)²

Thus use 2.8 - x = 2.8 and 2.6 - x = 2.6 in the above equation for Kc:

Kc = x²*(1.5*x)³ / 2.8²*2.6² = 3.375x^5 / 2.8²*2.6² = 0.06368*x^5

x^5 = 1.3*10^-6 / 0.06368 = 2.0414*10^-5

x = 0.115M

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.

if it's not useful, feel free to report for mistake in answer.

the answer your looking for is c).
