During a nuclear reaction, fuel rods generate a tremendous amount of heat. ... Problems cooling these pools have officials worried that the spent rods could ... appear to be related to one or more of the spent fuel storage pools at the plant. ... These fission byproducts are also very radioactive.

does that kind of help a little?

Answer:

They are scheduled for deep underground burial

Explanation:

Honestly none of these answers are correct in a sense.

They are no longer radioactive - This one is absolutely false since spent fuel rods remain dangerously radioactive for about for about 10,000 years

They contain only one type of isotope of the fuel (uranium) - There will be some 235 isotopes as well as some 238. Other isotopes might be present as well but only in very small amounts.

They usually remain radioactive for less than 100 years - As mentioned above, spent fuel rods remain dangerously radioactive for about 10,000 years.

They are scheduled for deep underground burial - This answer is probably the best as it it somewhat true. In the 1980's there was a plan launched by the federal government to bury spent fuel below Yucca Mountain in Nevada. However, this project was later called off to think of a better means of containment.

However...

Scandinavia and Finland have already approved an approach known as "deep storage" and have already begun to work on their own sites.

~Hope this helps!~

According to the law of constant composition, how many grams of oxygen does this isolated sample contain?
KatRina [158]

The Mass of oxygen in isolated sample is 8.6 g

<h3>What is the Law of Constant composition?</h3>

The law of constant composition states that pure samples of the same compound contain the same element in the same ratio by mass irrespective of the source from which the compound is obtained.

Considering the given ascorbic acid samples:

Laboratory sample contains 1.50 gg of carbon and 2.00 gg of oxygen

mass ratio of oxygen to carbon is 2 : 1.5

Isolated sample will contain 2/1.5 * 6.45 g of oxygen.

Mass of oxygen in isolated sample = 8.6 g

In conclusion, the mass of oxygen is determined from the mass ratio of oxygen and carbon in the compound.

#SPJ1

Note that the complete question is given below:

A sample of ascorbic acid (vitamin C) is synthesized in the laboratory. It contains 1.50 g of carbon and 2.00 g of oxygen. Another sample of ascorbic acid isolated from citrus fruits contains 6.45 gg of carbon. According to the law of constant composition, how many grams of oxygen does this isolated sample contain?

Express the answer in grams to three significant figures.

8.47 g

Given the chemical formulas of the following compounds, name each compound and state the rules you used to determine each name.
Svetlanka [38]
When naming an ionic compound, write the name of the cation, which is the metal first. Then, write the name of the anion, which is the nonmetal. However, you remove the last 2-3 letters and replace suffixes. 

1. RbF --> Rubidium Fluoride
Change fluorine to fluoride
2. CuO --> Copper (II) Oxide
Change oxygen to oxide. Oxide has a charge of -2. Since no subscripts are written, it means they have the same opposite charge. So, we use Copper (II).
<span>3. (NH</span>₄<span>)</span>₂<span>C</span>₂<span>O</span>₄  ---> Ammonium Oxalate
NH₄ is ammonia, but we change it to ammonium for polyatomic ions.
