at the nuclear reactor site
Explanation:
Most high-level wastes in the United States have been stored at the nuclear reactor site.
High-level wastes are radioactive wastes from nuclear activities in a reactor.
- They are mostly made up of spent rods and other radioactive materials.
- It is impossible to stop these materials from radiating.
- Radiations are toxic to life on earth.
- No known method has been properly designed to efficiently store nuclear waste.
- They are usually buried in large and dark underground storage facilities where they remain for several years

Answer:
[H₃O⁺] = 1.4 × 10⁻⁹ M.
Explanation:
NH₄Cl is a salt that dissolves well in water. The 2.5 M NH₄Cl will give an initial NH₄⁺ concentration of 2.5 M.
NH₃ is a weak base. It combines with water to produce NH₄⁺ and OH⁻. The opposite process can also take place. NH₄⁺ combines with OH⁻ to produce NH₃ and H₂O. The final H₃O⁺ concentration can be found from the OH⁻ concentration. What will be the final OH⁻ concentration?
Let the increase in OH⁻ concentration be x. The initial OH⁻ concentration at room temperature is 10⁻⁷ M.
Construct a RICE table for the equilibrium between NH₃ and NH₄⁺:
.
The value for ammonia is small. The value of x will be so small that at equilibrium, and .
.
.
.
Again, at room temperature.
When highly electronegative element like oxygen is directly attached to less electronegative element like hydrogen the electrons from less electronegative elements are attracted toward the highly electronegative element, making the less electronegative element deficient in electron density (partial positive) and a partial negative charge on more electronegative element is created. In such situation the intermolecular forces formed are dipole-dipole interactions or hydrogen bond interaction like in HF.
True
The main chemicals in air pollution that create acid rain are sulfur dioxide (SO2) and nitrogen (NOx).
