Answer:
The correct answer is - control rods.
Explanation:
Control rods are filled with special absorbing agents such as boron, cadmium, silver, and others to absorb as many neutrons as to control the fission reaction by moving them up and down in between uranium rods.
These control rods are used to prevent the nuclear reaction from getting out of control in the nuclear plant or reactor by absorbing the neutrons and prevent uranium to convert.

<span>What caused the bubbles to form when you added the catalyses to the hydrogen peroxide and water mixture at 40 °C? A. Catalyses activity heated the solution to its boiling point. B. Hydrogen gas formed during the formation of hydrogen peroxide. C. Oxygen gas formed during the decomposition of hydrogen peroxide.
This would be the water, mixture.</span>
Answer:
Ex1 = 4.3 moles
Explanation:
for Ex 1
** Number of mole = Mass (g) / Molecular weight ' Mw' (g/mole)
for a = NaCl , first you must be calculate Mw = look to periodic table
Atomic weight for Na is 22.9 = 23 g and for Cl is 35.45 = 35 g
so Mw for NaCl = 23+35 = 58 g/mole
so Number of Moles for NaCl 250 g is
Number of Moles = 250 / 58 = 4.3 moles
do same for others ...
good luck ..
