Answer:
Proximity to water bed/water sourceGeographical isolation and barriersunavailability of plant or any biosystemExplanation:
A nuclear repository would be required to be isolated with barriers in place to keep people out. Ideally, it should be stored underground and away from any underlying waterways, or biosystems so as to avoid contamination. A good example would be the proposed Yucca Mountain repository.
I hope this was helpful and useful.
The radioactive substance has a lot of distinction and variation and needs to be kept aside from the environment and it of reach for most nuclear power plants to discharge the gases.
There is various consideration that needs to keep in mind such as the size of the container, temperature of the gas, and amount of gas in the container. Other considerations include the closeness to water bed/water source, the locational isolation, and barriers , unavailability of plant or any biosystem in case of the nuclear wastes.Learn more about the characteristics that would be taken into consideration.

Ti(SO4)2 chemical compound?
Answer:
Titanium(IV) Sulfide
Explanation:
Why can you see solids and liquids, but not most gases?
Why can gases and liquids be paired but not solids?
The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.

How many grams of H2O are in 34.53 moles of H2O??
Answer:
m=621.54g
Explanation:
number of moles= mass of H2O/molar mass of H2O
n=m/mm
make mass the subject of the formula
m=n*mm
find molar mass of water
H2O=1(16)+2(1)
mm= 18.0g/mol. n=34.53mol
hence, m=34.53mol*18.0g/mol
m=621.54g

O D. Metal atoms have rearranged in the compounds.
SUBMIT
PREVIOUS
Answer: The Correct Answer is Choice B.
Explanation: I just took the quiz.
ANSWER:
B. Electrons have transferred from one atom to another.
EXPLANATION:
An oxidation-reduction (redox) reaction is a reaction which involves the change in oxidation number of the atoms involved. Since the oxidation number changes, this means that one atom has to lose electrons and another has to accept electrons. The reactant that loses electrons is called REDUCING AGENT while the reactant that gains electrons is called OXIDIZING AGENT.
For example, in a reaction between iron and oxygen as follows:
4Fe+ 3O2→2Fe2O3
Iron is reduced from +2 to 0 because it accepts electrons from oxygen while oxygen is oxidized from -2 to 0 because it transfers electrons to iron.
Hence, a redox reaction can be identified by the transfer of electrons from one atom to another.

What is the definition of climate?
1) An area's long term weather pattern
2)When large air masses of different density, moisture, and temperature mee
3)The state of the atmosphere at a given place and time
4)Large volume of air that has similar characteristics of temperature and water
vapor content
Answer:
1) An area's long term weather pattern
Explanation:
Climate is defined as the weather pattern in an area for the long term. Climate means the usual condition of the humidity, temperature, wind, rainfall, and atmospheric pressure in the surface area of Earth for the long term. Usually the time period for a climate in a region is taken over 30-years.
Weather is the state of the atmosphere and climate the long-term weather pattern of the area. For example: degree to which it is hot or cold is weather and expect snow in the Northeast in every January is climate.
Hence, the correct answer is "1) An area's long term weather pattern".

The right alternative is Option D (0.78 V).
According to the question,
By putting the values, we get

Ag+1 + 1e Ag E° = 0.78 V
= 1.23 - 0.45

30 POINTS HELP Which idea was supported by Aristarchus, Copernicus, and Galileo?
The planets have epicycles.
The planets revolve around the Sun.
The stars rotate around the Sun.
The center of the solar system is Earth.
Answer:
SO SORRY it took so long but the answer is B :)
Explanation:
Trust me and good luck :)
The theory that the planets move around the sun was endorsed by Aristarchus, Copernicus, as well as Galileo. The solar system revolves around the sun.
What is Aristarchus?Aristarchus of Samos was just a Greek astronomer that suggested the very first heliocentric model of the cosmos, wherein the sun, rather than the earth, was even at its center. Despite the fact that his hypothesis was acknowledged by other philosophers of the time, it was dismissed as unrealistic, and the geocentric model remained in use for the next 1,700 years.
What is Copernicus?Copernicus was also the first to assert that the Earth as well as the other planets orbit the sun. It was really a significant shift in thinking.
What is sun?Sun can be considered as a star in solar system.
The theory that the planets move around the sun was endorsed by Aristarchus, Copernicus, as well as Galileo. The solar system revolves around the sun.
Therefore, the correct answer will be option (b).

Where the diluted solution is #2 (the numerator)
Answer:
V₁ = 0.019 L
Explanation:
Given data:
Molarity of stock solution = 10.0 M
Volume of stock solution = ?
Molarity of CaCl₂ = 0.25 M
Volume of CaCl₂ = 0.75 L
Solution:
Formula:
V₁ = M₂V₂ / M₁
V₁ = 0.25 M × 0.75 L / 10.0 M
V₁ = 0.1875 M.L / 10.0 M

Would you expect oxygen (O) to react more like sulfur (S) or nitrogen (N)? Support your prediction with evidence .
Answer:
Sulfur
Explanation:
Oxygen like sulfur would chemical react and combine with other compounds in the same way. This is because they are both located in the same group on the periodic table.
Elements in the same group have the same chemical properties and they will react the same way.
The general formula of the elements in this group are ns² np⁴.
All the elements in this group have 4 electrons in their np⁴ shell and they belong to the p-block.
How does knowing the reactants and products
help you classify a chemical reaction? Write a
short paragraph explaining.
Answer:
Here's the Sample Response: The reactants and products determine the type of chemical reaction. If there are more products than reactants, then it is a decomposition reaction. If there are more reactants than products, it is a synthesis reaction. If oxygen is a part of the reactant, it is a combustion reaction. If one ion replaces another, it is a single replacement reaction. If there are two compounds in a reactant where cations switch, it is a double replacement reaction.

Decide which element probably forms a compound with hydrogen that has a chemical formula most and least similar to the chemical formula of the compound formed by hydrogen and sulfur.
Answer:
Most similar- oxygen
Least similar- sodium
Explanation:
The complete question is shown in the image attached.
Now let us consider all the options in the questions carefully. We do know that hydrogen forms covalent bonds with sulphur. Two hydrogen atoms form form two polar covalent bonds with one sulphur atom. The molecule is bent owing to the presence of two lone pairs of electrons on the sulphur central atom.
Oxygen is in the same group as sulphur in the periodic table. The compound between hydrogen and sulphur is strikingly similar to the compound formed between sulphur and hydrogen due to chemical similarity of compounds of elements in the same group of the periodic table. Hence H2O bears the greatest similarity to H2S.
The bond between hydrogen and halogens is also polar covalent but less similar to the bond between sulphur and hydrogen.
Lastly, the bond between hydrogen and sodium is ionic and least similar to the bond between hydrogen and sulpur. We actually have in that compound, Na^+ H^-. Sodium transfers one electron to hydrogen as is implied in the ionic formula shown.
Hence the answer above.
