In 2015, only 9% of the electricity used in the U. S. was generated from nuclear power. What are some of the costs associated wi

th using nuclear power instead of traditional energy sources such as fossil fuels? All BUT ONE would be considered a cost.
A)The potential of nuclear disasters and radioactive incidents such as the Daiichi nuclear disaster.
B) Nuclear power plants can work with renewable energy sources such as solar and wind power when they are not available.
C) The nuclear fission reaction is able to produce cheap electricity but also dangerous radioactive waste that is hard and expensive to dispose.
D) Uranium and plutonium are finite sources of energy. With the current level of consumption in the nuclear power plants uranium will run out in eighty years.

What is the only type of plate inaction that can cause an earthquake to be 9.0 on the Richter Scale?​
Sedaia [141]

Answer: Subduction zone

Explanation: How do we know the subduction zone exists here? Mostly because of geological data left behind by subduction zone earthquakes, known as megathrust earthquakes. Subduction zones are the only type of plate meeting that can cause earthquakes greater than magnitude 8.5, according to the Pacific Northwest Seismic Network.

Ml of 0.00237 m nai (aq) is combined with 625. ml of 0.00785 m pb(no3)2 (aq). determine if a precipitate will form given that th
Talja [164]
The volume of I- is missing in your question by assuming it = 1L
moles I- =  molarity * volume

              = 0.00237 * 1 L 

              = 0.00237 mol

[I-] = moles / total volume
 
    = 0.00237 / 1.625L
   
    = 0.00146 M

moles Pb2+ = molarity * volume 

                     = 0.00785 * 0.625 L

                    = 0.0049 mol 
  
[Pb2+] = 0.0049 / 1.625L

           =  0.003 M 


when        PbI2(s)  ↔     Pb2+(aq)  +  2I-(aq)


when Q = [Pb2+][I-]^2    and we neglect [PbI2] as it is solid

 ∴ Q = 0.003  * (0.00146)^2

        = 6.4 x 10^-9

by comparing the value of Q with Ksp value  we will found that:

Q < Ksp which mean that more solid will dissolve, and this is an unsaturated solution which has ion concentrations < equilibrium concentrations, so the reaction will go forward until achieving equilibrium.
