Answer: The correct answer is option A.
Explanation:
There are 2 types of nuclear reactions:
1. Nuclear fission reaction: In this type of reaction, a heavier nuclei splits into two or more lighter nuclei. This process releases neutrons and further split additional atoms, generating into chain reactions.
where, A is heavier nuclei and B & C are lighter nuclei.
2. Nuclear fusion reactions: In this type, two lighter nuclei combines to form a single heavier nuclei.
where, A & B are lighter nuclei and C is a heavier nuclei.
In the given question, a heavier nuclei is splitting into two nuclei and releasing neutrons which are further splitting the two nuclei obtained into more nuclei. Hence, this is considered as a chain reaction which is caused by the splitting of nuclei or nuclear fission reaction.
Hence, the correct answer is Option A.

Answer:
Density of the solid=
Explanation:
We are given that
Mass of sample of metal=4.369 g
Volume in the flask, V=126.4 ml
Mass of water, flask, and metal=268.5 g
Mass of flask=139.3 g
Density of water=1.000 g/mL
We have to find the density of the solid.
Mass of water=268.5-4.369-139.3=124.831 g
Volume of water=
Volume of water=
Volume of solid=126.4 ml-124.831 mL
=1.569mL
Now,
Density of the solid=
=
1mL=1 cubic cm
Therefore,
Density of the solid=
Potassium Selenium = K2Se
