Answer : When the nuclear reaction produces too many neutrons.

Explanation : In a nuclear fission reactor where the reaction is controlled by regulating the number of neutrons produced by the chain reaction. Production of too many neutrons may cause an accelerated uncontrolled chain reaction which may cause enormous heat to be generated in a very short period of time inside the reactor which may result into an explosion.

For, this purpose control rods, made of neutron absorbing species, like cadmium, are placed in the nuclear reactors to control the excess number of neutrons at any point of reaction when required.

What is the pressure of 5.0 mol nitrogen gas in a 2.0 L container at 286 K
g100num [7]
The "Ideal Gas Law Equations" is 
PV=nRT
P= Pressure (in Pascals)
V=Volume (in Liters)
n=amount, or <u>n</u>umber (in moles)
R= 8.3145 \frac{Pascals*Liters}{Moles*Kelvin} or \frac{PaL}{molK}
T= Temperature (In Kelvin)

P= \frac{nRT}{V}

Plug into the equation and you're good!
P=\frac{nRT}{V}
P =\frac{(5mol)(8.3145)(286K)}{2L}
P=5944.8675Pa

If your teacher cares about sig figs,
2 sig figs (significant figures)
P=5900Pa

For other units of pressure,
1 atm = 760 mmHG = 760 Torr = 101326 Pa = 1.01325 bar<u />

solong [7]

Answer:

1s2: correct.

6s3: incorrect because the subshell s can hold up to 2 electrons.

5f10: correct.

4d3: correct.

2d4: incorrect because the second energy level just has the s and p subshells.

Explanation:

Hello there!

In this case, according to the attached file, which shows the correct orbitals and electrons, we can proceed as follows:

1s2: correct.

6s3: incorrect because the subshell s can hold up to 2 electrons.

5f10: correct.

4d3: correct.

2d4: incorrect because the second energy level just has the s and p subshells.

3p10: incorrect because the p subshell can hold up to 6 electrons.

Best regards!
