Which radioisotope requires long-term storage as the method of disposal, to protect living things from radiation exposure over time?
Pu-239
FR-229
Fe-53
P-32

Answers

Answer:pu-239

Explanation:

Pu-239 is regarded as the radioisotope requires long-term storage as the method of disposal, to protect living things from radiation exposure over time

Disposal of radioactive nuclear waste is often regarded as a problem.

The waste sources are:

Nuclear power reactors Bomb-related nuclear material

Disposal of bomb-grade plutonium is often difficult.

The longer lived isotopes are:

Plutonium-239 whose t1/2 is 24,110 years, Plutonium-240 whose t1/2 is 6,540 years, Curium-245 whose t1/2 is 8,500 years. etc.

The storage of the longer lived elements is through containment for the next several thousand of years.

The control or management of radioactive waste is a hard, multifaceted procedure.

What is the mass of 3.25 moles of sodium hydroxide (NaOH)?

Answers

Answer:

1 mole is equal to 1 moles NaOH, or 39.99711 grams.

Explanation:

Hope this helps have a nice day :)

The statement of the mass of sodium hydroxide (NaOH) is "130 g."

What is mass?

A substance is something to do with mass that takes up space. The mass of a compound is the total amount of atoms present in grams that make up a molecule. The grams is the unit of mass.

In order to determine the mass in grams, multiply moles of the substance value by its molar mass to convert moles into grams.

Mole to gram conversion factor,

[tex]=\;given \;mole\;.\;\frac{grams}{1\;mol}[/tex]

Mass of NaOH comes out to be,

[tex]=\;3.25\;mol\;.\;\frac{39.997\;g}{1\;mol}[/tex]

= 129.99 g

= 130 g

Hence the correct answer is 130 g.
