What are the prompt neutrons that occur during nuclear fission?

Chemistry

Answer:

Prompt Neutrons

Explanation:

Principle. Using uranium-235 as an example, this nucleus absorbs thermal neutrons, and the immediate mass products of a fission event are two large fission fragments, which are remnants of the formed uranium-236 nucleus. These fragments emit two or three free neutrons (2.5 on average), called prompt neutrons.

Is the solution containing 0.20 M Pb2 and 0.10 M Cl (Ksp 1.6x105) a) saturated, b) unsaturated, c) at equilibrium, d) none of th
raketka [301]

Answer : The correct option is, (b) unsaturated

Explanation :

Ionic product : It is defined as the product of the concentrations of the ions present in solution raised to the same power by its stoichiometric coefficient in a solution of a salt. This takes place at any concentration. The ionic product is represented as, Q.

Solubility product constant : It is defined as the product of the concentration of the ions present in a solution raised to the power by its stoichiometric coefficient in a solution of a salt. This takes place at equilibrium only. The solubility product constant is represented as, K__{sp}.

Now we have to calculate the ionic product of given solution.

The balanced chemical reaction is,

PbCl_2(aq)\rightarrow Pb^{2+}(aq)+2Cl^-(aq)

The expression of ionic product will be,

Q=[Pb^{2+}][Cl^-]^2

Q=(0.20)\times (0.10)^2

Q=0.002

The ionic product of solution is, 0.002

There are three cases for the solubility :

When Q this means that the solution is unsaturated solution and more solid will be dissolve.

When Q=k_{sp} this means that the solution is saturated solution.

When Q>k_{sp} this means that the solution is supersaturated solution and solid will be precipitate.

From this we conclude that the value of k_{sp}=1.6\times 10^5 is greater than the ionic product that means the solution is unsaturated solution and more solid will be dissolve.

Hence, the correct option is, (b) unsaturated
