When the element is reduced it gains electrons, maybe it's charge becomes more negative.
Raising the control rods out of the reactor
The reactor regulates the number of neutrons that are involved in the chain reaction. This is accomplished by the reactor absorbing some of the neutrons, produced in the splitting of the atoms, in its walls.
Explanation:
If the rods are taken out of the reactor, the rods would heat up very fast and most probably an explosion would occur. This is because most of the neutrons produced in the splitting of the radioactive atoms in the rod would go ahead and bombard other atoms in the rods hence spiking up the chain reaction rate. This would release a lot of energy at a go.

Answer: 7.88 grams
Explanation:
Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.
where,
n = moles of solute
= weight of solvent in kg
moles of solute =
mass of solvent = 97 g = 0.097 kg (1kg=1000g)
Now put all the given values in the formula of molality, we get
Therefore, the mass in grams of potassium chloride that must be added to 97 g of water to make a 1.09 m solution is 7.88
