Answer: because it is
Explanation: to be honest is just is there is not explanation needed
Answer:
pH= 3, 00 (acidic solution), pOH= 7,00
Explanation:
The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and higher than 7 to 14 basic. It is calculated as
pH = -log (H 30+)
pH= -log (0.001)
pH=3, 00 (the solution is acidic because the pH is less than 7,00)
We know that the sum of the pH and pOH is 14, so we solve pOH:
pH + pOH= 14
3, 00 + pOH=14
pOH= 14 - 3,00= 7, 00
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.
