Chemistry

Answer:

C and D on the attached picture.

Explanation:

Hello,

At first, it is important to remember that a cyclohexane beat conformation is a possible shape adopted by this molecule.

In this case, boat conformations are said to be in equilibrium, it means a condition at which the opposing force or influence is balanced with the conformation force. In such way, no changes are noticed as a function of time due to their stability. Thus, the two structure attaining the equilibrium are C and D (attached picture) as result of the distancing between the included radicals.

Best regards.

The structure of boat confirmation for any cyclohexane be like as shown in figure (1)

The two substituents are

ethyl : at 1st position

isopropyl: at fourth position

So possible combinations for structures are shown in figure (2)

So the correct answer is

figure (3)

The decomposition of NH4HS is endothermic: NH4HS(s)⇌NH3(g)+H2S(g) Part A Which change to an equilibrium mixture of this reaction
shepuryov [24]

Explanation:

According to Le Chatelier's principle, any disturbance caused in an equilibrium reaction will shift the equilibrium in a direction that will oppose the change.

As the given reaction is as follows.

       NH_{4}HS(s) \rightleftharpoons NH_{3}(g) + H_{2}S(g)

(a)  When increase the temperature of the reactants or system then equilibrium will shift in forward direction where there is less temperature. It is possible for an endothermic reaction.

Thus, formation of H_{2}S will increase.

  • (b)  When we decrease the volume (at constant temperature) of given reaction mixture then it implies that there will be increase in pressure of the system. So, equilibrium will shift in a direction where there will be decrease in composition of gaseous phase. That is, in the backward direction reaction will shift.

Hence, formation of H_{2}S will decrease with decrease in volume.

  • When we increase the mount of NH_{4}HS then equilibrium will shift in the direction of decrease in concentration that is, in the forward direction.

Thus, we can conclude that formation of H_{2}S will increase then.
