A nuclear power plant is scheduled to undergo a retrofitting. What is the most likely outcome of the change?
The power plant will no longer generate radioactive wastes.
The power plant will recycle the water it uses to cool the reactor.
The power plant will be able to reprocess its used uranium fuel.
The power plant will switch from fission reactions to fusion reactions.
Answer:
It's B
Explanation:
I got it right on edjenuity
The most likely outcome of the retrofitting of a nuclear power plant is that it will be able to reprocess its used uranium fuel. Therefore, option C is correct.
What is nuclear power plant?A nuclear power plant is a facility that generates electricity by harnessing the heat produced by nuclear reactions. At the heart of a nuclear power plant is the reactor, where a controlled chain reaction of nuclear fission occurs.
Reprocessing is a process by which the used nuclear fuel is chemically treated to separate out and recover the unused uranium and plutonium, which can then be reused as fuel. This reduces the amount of radioactive waste produced by the plant and also extends the life of the uranium fuel.
The fission reactions to fusion reactions is not currently a viable option for power generation, and the idea that a retrofitting would eliminate radioactive wastes is unlikely, as nuclear power plants will always produce some amount of radioactive waste.
Thus, option C is correct.

Whenever the same two elements form more than one
compound, the different masses of one element that combine
with the same mass of the other element are in the ratio of
small whole numbers.
TRUE
FALSE
Answer:
The answer is true
Explanation: Because The law of multiple proportions states that when two elements react to form more than one compound, a fixed mass of one element will react with masses of the other element in a ratio of small, whole numbers.
What mass of solute should you measure out in order to make 1,000 mL of a 0.3 M solution of magnesium phosphate Mg3(PO4)2?
Hey there !
Molecular Weight: 262.86 g/mol
Volume in liters : 1,000 mL => 1,000 / 1000 => 1 L
Number of moles of solution :
number of moles = volume x molarity
number of moles = 1 x 0.3 => 0.3 moles
Therefore:
1 mole Mg₃(PO₄)₂ ------------------- 262.86 g
0.3 moles ----------------------------- mass of Mg₃(PO₄)₂ ??
mass of Mg₃(PO₄)₂ = 0.3 x 262.86 / 1
mass of Mg(PO₄)₂ => 78.858 g
Hope this helps!

Will give brainliest, Look at the graph above. Compare it to the periodic table. What do you notice about the location on the periodic table of the elements that represent the high points
Answer:
We can see that the atomic radius decreases across every row.
Explanation:
I will comment more below.
The elements that represent the highest points on the graph are all elements of group 1 and occur at the head of the period to which they belong.
The periodic table is an arrangement of elements in groups and periods. The elements in the same group have the same number of valence electrons while the elements in the same period have the same number of shells.
Looking at the graph, we can see that the high points in the graph all correspond to the group 1 elements; sodium, potassium, rubidium and cesium.The have the highest atomic radii in the period. Atomic radii increases down the group but decreases across the period. Remember that these elements are at the head of the period to which they belong hence they have the highest atomic radii.

The atom is one of the basic units of matter. Which part of the atom mostly determines the size of the atom?
a.Electrons
b.Nucleus
c.Neutrons
d.Protons
Answer:
Atomic size is the distance from the nucleus to the valence shell where the valence electrons are located. The separation that occurs because electrons have the same charge. The number of protons in the nucleus. The core electrons in an atom interfere with the attraction of the nucleus for the outermost electrons.

A muffin has a mass of 100g and a volume of 500cm3. What the density of the muffin? Show all work
Answer:
The density of muffin is 0.2 g/ cm³.
Explanation:
Given data:
Mass of muffin = 100 g
Volume of muffin = 500 cm³
Density of muffin = ?
Solution:
Density is equal to the mass of an object divided by its volume.
Formula:
d = m/v
Now we will put the values in formula.
d = 100 g/ 500 cm³
d = 0.2 g/ cm³
The density of muffin is 0.2 g/ cm³.

what mass of calcium chloride will be produced from 3.750 moles of hcl reacting with ca(oh)2
Answer:
208.125g
Explanation:
Given parameters:
Number of moles of HCl = 3.75moles
Unknown:
Mass of CaCl₂ that will be produced = ?
Solution:
The reaction equation is given as:
2HCl + Ca(OH)₂ → CaCl₂ + 2H₂O
Now, to find the mass of CaCl₂, we have to work from the known to the unknown.
The known specie here is the number of moles of HCl;
2 mole of HCl will produce 1 mole of CaCl₂
3.75moles of HCl will produce [tex]\frac{3.75}{2}[/tex] = 1.875moles
The mass of CaCl₂;
Mass of CaCl₂ = number of moles of CaCl₂ x molar mass
Molar mass of CaCl₂ = 40 + 2(35.5) = 111g/mol
Mass of CaCl₂ = 1.875 x 111 = 208.125g

O A. O
O B. C
O C. B
O DN
Answer:
the answer is D. N
AP3X
According to electronic configuration, there are 3 electrons in the 2p sublevel ,hence the correct option is D.
Electronic configuration is defined as the distribution of electrons that are present in an atom or molecule in an atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is important for understanding the structure of periodic table. It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions so as to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in their ground state and hence are said to be stable.
Thus, the correct option is D.
