Answer:
Uranium-235 absorbing a neutron and breaking into Barium-141, Krypton-92 and three neutrons
Explanation:
A fission reaction is said to have occurred when an unstable nucleus is bombarded with a neutron such that it disintegrates into daughter nuclei and produces more neutrons in the process. Hence, Uranium-235 absorbing a neutron and breaking into Barium-141, Krypton-92 and three neutrons is a fission reaction.
This fission reaction is often a self sustaining reaction. The neutrons produced in the reaction bombards more of the parent nucleus and the process continues indefinitely(chain reaction).
Control rods and moderators are used to keep the chain reaction in check.
Answer:
D
Explanation:
The greater the distance apart, the lesser the gravitational force between the objects
Answer : The molar mass of unknown substance is, 39.7 g/mol
Explanation : Given,
Mass of unknown substance = 9.56 g
Volume of solution = 100.0 mL
Molarity = 2.41 M
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the molar mass of unknown substance is, 39.7 g/mol
