U-235 undergoes many different fission reactions. For one such reaction, when U-235 is struck with a neutron, Ce-144 and Sr-90 a
Lostsunrise [7]

Explanation:

A nuclear fission reaction is defined as the reaction in which a heavy nucleus splits into small nuclei along with release of energy.

The given reaction is ^{235}_{92}U + ^{1}_{0}n \rightarrow ^{144}_{58}Ce + ^{90}_{38}Sr + x^{1}_{0}n + y^{0}_{-1}\beta

Now, we balance the mass on both reactant and product side as follows.

         235 + 1 = 144 + 90 + (x \times 1) + (y \times 0)

           236 = 234 + x

            x = 236 -234

               = 2

So, now we balance the charge on both reactant and product side as follows.

              92 + 0 = 58 + 38 + (x \times 0) + (y \times -1)

                92 = 96 - y

                  y = 4

Thus, we can conclude that there are 2 neutrons and 4 beta-particles are produced in the given reaction.

Therefore, reaction equation will be as follows.

           ^{235}_{92}U + ^{1}_{0}n \rightarrow ^{144}_{58}Ce + ^{90}_{38}Sr + 2^{1}_{0}n + 4^{0}_{-1}\beta

Which of the following reactions shows that the rate of the appearance of D is twice the disappearance of A and one third the di
Delvig [45]
First, we are discussing reversible reactions here, since the reaction is proceeded in both directions forming both reactants and products.

The reaction is symbolized as:
A + B <.........> C + D

The first given is:
The rate of appearance of D is twice the disappearance of A
This means that the coefficient of D in the reaction is twice the coefficient of A

The second given is:
The rate of appearance of D is one third the disappearance of B.
This means that the coefficient of D in the reaction is 1/3 that of B. This also means that the coefficient of B is 3 times that of D.

Combining these two pieces of information, we will find that the best equation that resembles this scenario is:
<span>A + 6 B <.........> C + 2 D </span>
