I think it’s the second one!! Hope this helps! BRANLIEST plzzzz
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:
Holly observes that the ice pack becomes colder when she activates it.
Explanation:
She infers that the process of the urea dissolving in water is endothermic.
The molarity of her solution will be 1.88 M
<h3>What is Molarity ?</h3>
Molarity is defined as the number of moles of solute dissolved in per litre of solution.
Molarity of the solution = number of moles of solute / volume of solution in litre
number of moles of solute = given weight / molecular weight
= 43.3 / 45.95
= 0.942 moles
Now, lets calculate Molarity ;
Molarity of the solution = number of moles of solute / volume of solution in litre
= 0.942 / 0.500
= 1.88 M
Hence, The molarity of her solution will be 1.88 M
