The test for this is fairly simple.
We take a glowing match or splint near the gas sample, if the glow intensifies, oxygen is present.
If a lit splint or match goes out with a popping sound, this means that hydrogen is present.

URGENT!!!!!!!!Which reaction takes place in a nuclear fission reactor?

ivolga24 [154]

<u>Answer:</u> The correct answer is Option d.

<u>Explanation:</u>

Nuclear fission reaction is defined as the reaction in which 1 heavier nuclei splits into two or more smaller nuclei.

As, nuclear fission reactors require a large amount of energy to split the nucleus, hence it is bombarded with a particle in order to star the reaction.

In a nuclear reaction, a large fissile atomic nucleus like Uranium-235 $(_{92}^{235}\textrm{U})$ or Plutonium-239 $(_{94}^{239}\textrm{Pu})$ when absorbs a neutron, it undergoes nuclear fission reaction.

Hence, in the given options, uranium-235 is absorbing a neutron. Therefore, the correct answer is Option d.
