Answer: The correct answer is option(A).

Explanation:

Regolith is defined as layer which is composed of heterogeneous, loose, uppermost deposits covering the solid rock. They complete different from soil. It includes dust, soil, broken rocks and other related material. They arenot only present on earth but on another terrestrial bodies also like : moon ,asteroids ,mars etc.

So, from the enlisted option the correct description of regolith is given by option(A). Hence, option(A) is correct.

Acetylene, C2H2, can be converted to ethane, C2H6, by a process known as hydrogenation. The reaction is C2H2(g)+2H2(g)?C2H6(g)

Alecsey [184]

Answer:

Keq =1.50108

Explanation:

The given reactionis

C₂H₂(g) +2H₂(g) -------------> C₂H₂(g)

ΔG0 f=ΔG0f n (products) - ΔG0f n (reactants )

= -32.89 kJ/mol - (209.2 kJ/mol+2*0.0 kJ/mol)

= - 242.09kJ/mol

ΔG= -RTlnKeq

ln Keq = -ΔG/RT

=-(- 242.09kJ/mol ) / 2 k cal /mol*298 K

=0.406

Keq =e0.406

Keq =1.50108

Gaseous hydrogen iodide is placed in a closed container at 425∘C, where it partially decomposes to hydrogen and iodine: 2HI(g)⇌H

murzikaleks [220]

Answer:

0.0184

Explanation:

Let's consider the following reaction at equilibrium.

2 HI(g) ⇌ H₂(g) + I₂(g)

The concentration equilibrium constant (Kc) is equal to the product of the concentration of the products raised to their stoichiometric coefficients divided by the product of the concentration of the reactants raised to their stoichiometric coefficients.

Kc = [H₂] × [I₂] / [HI]²

Kc = (4.78 × 10⁻⁴) × (4.78 × 10⁻⁴) / (3.52 × 10⁻³)²

Kc = 0.0184
