Option B is correct

K = Kp /Kr

The given equation indicating, the product containing 6 moles of proton whereas the reactant contains 2 mole of bismuth and 3 mole of hydrogen sulphide.

Hence, in reaction B there are 2 mole of bismuth and 3 mole of hydrogen sulphide reacting to produce 6 moles of proton. whereas the concentration of Bi2S3 is not considered as it is present in solid phase.

Answer:

2Bi2+(aq) + 3H2S(aq)↔ Bi2S3(s) + 6H+(aq)

Explanation:

In general for a hypothetical reaction:

x(Reactants) ↔ y(Products)

the equilibrium constant, Keq is given by the ratio of the products to that of the reactants raised to the appropriate coefficients.

Keq = \frac{[Products]^{y} }{[Reactants]^{x} }

The given Keq is:

Keq = \frac{[H+]^{6}}{[Bi2+]^{2} [H2S]^{3} }

This implies that the reactants are: H2S (aq) and Bi2+(aq)

Products are: H+(aq)

Therefore the reaction with the appropriate coefficients would be:

2Bi2+(aq) + 3H2S(aq)↔ Bi2S3(s) + 6H+(aq)

Since the activity of solids = 1, Bi2S3 is not included in Keq

How much energy is required to vaporize 0.5kg of water?
White raven [17]

Answer:

Explanation:

Vaporization Equation => Q = m·ΔHv

m = 0.5Kg water = 500g water

ΔHv = Heat of vaporization = 540 calories/gram

∴Q = 500g x 540cal/g = 270,000 calories x 4.184 joules/cal = 1,129,680 joules = 1130 Kilojoules (3 sig. figs.)

When barium hydroxide is mixed with ammonium chloride, a fall in temperature is observed why? plz explain in detail
Oksanka [162]

Answer:

Ammonium chloride has ammonium (NH4 +) part which is slightly acidic and Barium Hydroxide is a strong base.

You can see that an acid-base reaction will occur.

In this case :

Its highly endothermic reaction

Forms aqueous ammonia (mind that ammonia is highly water soluble gas so no effervesence) and Barium Chloride which is water soluble.

Ba(OH)2 +NH4Cl ——->BaCl2 + NH3 +H2O (unbalanced)
