s increased? View Available Hint(s) Which equilibrium reaction will experience a shift towards the products in equilibrium position when the concentration of is increased? Ni(OH)2(s)⇌Ni2+(aq)+2OH−(aq) [Ni(H2O)6]2+(aq)+3en(aq)⇌[Ni(en)3]2+(aq)+6NH3(aq) Ni2+(aq)+6NH3(aq)⇌[Ni(NH3)6]2+ NiS(s)⇌Ni2+(aq)+S2−(aq)

Explanation:

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

As the given reactions are as follows.

  •  Ni(OH)_{2}(s) \rightleftharpoons Ni^{2+}(aq) + 2OH^{-}(aq)

When concentration of Ni^{2+} is increased in this reaction then reaction will shift in a direction that will be opposing the change. This means that the reaction will shift in backward direction.

  • [Ni(H_{2}O)_{6}]^{2+}(aq) + 3en(aq) \rightleftharpoons [Ni(en)_{3}]^{2+}(aq) + 6NH_{3}(aq)

In this reaction, both water and ethylenediamine are neutral molecules. Hence, charge on nickel on each side will be equal to +2. Therefore, reaction will remain in equilibrium.

  • [Ni^{2+}(aq) + 6NH_{3}(aq) \rightleftharpoons [Ni(NH_{3})_{6}]^{2+}(aq)

When we increase the concentration of Ni^{2+} then equilibrium reaction will shift in the forward direction.

  • [NiS(aq) \rightleftharpoons Ni^{2+}(aq) + S^{2-}(aq)

Here, on increasing the concentration of Ni^{2+} will shift the equilibrium in backward direction.

Thus, we can conclude that out of the given options [Ni^{2+}(aq) + 6NH_{3}(aq) \rightleftharpoons [Ni(NH_{3})_{6}]^{2+}(aq) is the chemical reaction in which equilibrium reaction will experience a shift towards the products in equilibrium position when the concentration of Ni^{2+} is increased.

18. Describe the relationship between kinetic energy and mass, and give an example of
lidiya [134]

Answer:

Kinetic energy is directly proportional to mass

Explanation:

Kinetic energy is directly proportional to the mass of an object and also directly proportional to the square of the velocity of that object:

E_k = \frac{1}{2} mv^2

Notice that if we keep velocity constant and only increase the mass of a object, the kinetic energy of that object would increase, as we've already emphasized the direct relationship between the kinetic energy term and the mass term.

Let's take a simple example: assume that object 1 and object 2 are both moving at the same velocity but object 1 has a much lower mass than object 2. According to the equation, object 1 has lower kinetic energy. This object can then transform all of its kinetic energy into some other form, say, heat the ground. The heat transferred will be significantly lower than by the object 2 moving at the same velocity but having a much greater mass.
