Given question is incomplete. The complete question is as follows.

The decomposition of NH_{4}HS is endothermic:

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

Which change to an equilibrium mixture of this reaction results in the formation of more H_{2}S?

a decrease in the volume of the reaction vessel (at constant temperature), an increase in temperature, an increase in the amount of NH_{4}HS in the reaction vessel, all of the above.

Explanation:

As per Le Chatelier's principle, any disturbance caused in an equilibrium reaction will tend to shift the equilibrium in a direction away from the disturbance.

When volume is decreased then there will occur increase in pressure because according to Boyle's law pressure is inversely proportional to volume.

Hence, equilibrium will shift in the direction where there is less pressure. Therefore, in the given reaction a decrease in the volume of the reaction vessel (at constant temperature) will shift the equilibrium in the backward direction.

When we increase the temperature then more number of collisions will take place and product formation will be more. Hence, reaction will shift in the forward direction.

When amount of NH_{4}HS increases then equilibrium this disturbance will shift the equilibrium in forward direction.

Thus, we can conclude that following change to an equilibrium mixture of this reaction results in the formation of more H_{2}S:

  • an increase in temperature.
  • an increase in the amount of NH_{4}HS in the reaction vessel.

Evgen [1.6K]

Answer:

The sun radiates energy in all directions.

Explanation:

Most of it dissipates into space, but the tiny fraction of the sun's energy that reaches Earth is enough to heat the planet and drive the global weather system by warming the atmosphere and oceans

A cat travels 240 meters in 30 seconds, and a sprinter travels 100 meters in 9.5 seconds. Which is traveling faster, the cat or
joja [24]

Answer:

The cat

Explanation:

1) You need to find how many meters per second each thing is sprinting, so you can divide the meters by seconds for each.

\frac{240}{30} = 8 m/s\\\frac{100}{9.5} = around  10.5 m/s

2) Per second, the sprinter is able to achieve 8 meters, while the cat can do around 10.5 meters. 10.5 is greater than 8, making the cat faster than the sprinter.
