Answer:
The most likely reason is that spent fuel bars can infect the community with radiation causing numerous health problems.
Explanation:
A spent fuel is a fuel that has been exposed to irradiation in a nuclear reactor. This fuel expels radiation and this is one of the main reasons why a group of people oppose the storage of spent fuel bars in their community. This is because through this fuel can occur a leak of radiation contaminating the community and generating major health problems.

Hello there!
In this case, according to the given chemical reaction, it is possible for us to realize that the 46.2 kJ of energy are given per mole of reaction, which are related to 3 moles of hydrogen; Thus, we can calculate the energy per mole of hydrogen as shown below:
Now, to calculate the total energy, we convert the grams to moles of hydrogen as shown below:
Best regards!
Answer:
(Incomplete question)
Assuming the molarity of the weak acid is 17.4 M, the answer would be 52.4mL.
Explanation:
Equivalence point is defined as the point where moles of titrant = moles of titrand (analyte).
At equivalence point,
# moles of NaOH = # moles of weak acid
# moles of NaOH = 0.1236 × 12.43 mL
= 0.1236 mol/L × 0.01242 L
= 0.00153511 moles of NaOH
= 0.00153511 moles of weak acid.
Since the concentration of acid is not stated in your question, we will assume the concentration of the acid to be 17.4 M.
concentration = no. of moles ÷ volume
⇒ vol. = no. of moles ÷ conc.
= 0.00153511 mol ÷ 17.4 mol/L
= 0.0267 L ≈ 26.7 mL
This means that the total volume of the solution at the half equivalence point will be:
26.7 mL + 26.7 ml
= 52.4 mL.
N.B: Confirm missing variable from question: it could be concentration or volume of acid,but it is impossible to have two unknowns. Also, incase its pH of acid that's given, you can solve problem using Henderson-Hasslebauch equation.
We have to know whether F₂²⁺ is paramagnetic or diamagnetic.
F₂²⁺ is paramagnetic.
If number of unpaired electron in any species is equal to zero, the species is diamagnetic and the species contains unpaired electrons, then the species is paramagnetic.
The magnetic property can be explained using molecular orbital theory.
Total number of electron present in F₂²⁺ is equal to 16 (i.e, 9+9-2). From the molecular orbital electronic configuration, number of electrons present in pi orbitals present is equal to 2.
So, F₂²⁺ is paramagnetic.
Answer : is paramagnetic.
Explanation :
According to the molecular orbital theory, the general molecular orbital configuration will be,
As there are 9 electrons present in fluorine.
The number of electrons present in molecule = 2(9) - 2 = 16
The molecular orbital configuration of molecule will be,
Paramagnetic compounds : They have unpaired electrons.
Diamagnetic compounds : They have no unpaired electrons that means all are paired.
The number of unpaired electron in molecule is, 2. So, this is paramagnetic. That means, more the number of unpaired electrons, more paramagnetic.
Thus, is paramagnetic.
Answer:
The volume of balloon is 5.41 L.
Explanation:
The volume of helium (V1) = 5 L
Temperature (T1) = 1 degree Celsius
Now covert the temperature into kelvin by simply adding the 273 with given temperature. Thus, 1-degree Celsius = 274 kelvin.
The volume of balloon (V2) =?
Temperature (T2) = 24 degree Celsius
Now covert degree Celsius into kelvin. Thus, 24-degree Celsius = 297 kelvin.
Using Charl’s law.
Answer:
Change in height of the object
Explanation:
Change in height of the object
Since ,
We know potential energy can be written as mgh where
P.E. = mgh
M = mass ,
g = gravity constant
h = height
Kinetic energy can be written as 0.5 mv²
So , the Potential energy = kinetic energy
Then ,
velocity of object = √2 gh
Since g is a constant ,
Hence ,
Height of object will determine the velocity.
Answer:
Newton’s law of inertia is illustrated in tests with crash dummies, seat belts, and airbags, wherein the object stays in motion unless there is an unbalanced force applied to it.
Inertia is the main reason why there are seatbelts and airbags in the car. In this case, when the seatbelt is trapped to the passenger, the passenger experiences the same state of motion as the car. If the car accelerates/decelerates, the passenger experiences it too. When the car experiences collision, an unbalance force is acted upon it. This causes the car to stop abruptly, and the passenger shares the same state of motion because of the seatbelt and the airbags that apply the unbalanced force to stop the passenger to go forward.
