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.

Answers

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.

Carbon dioxide consists of a central carbon atom with an oxygen atom on each side. Draw a model of the molecule formed by putting lines between the atoms to represent bonds so that each atom has the correct number of bonds.

Answers

Answer:

O=C=O

Explanation:

PLATO ANSWER

In carbon dioxide (CO₂), bonding occurs through a combination of covalent and double covalent bonds between the carbon atom and the oxygen atoms.

Carbon dioxide is a linear molecule composed of one carbon (C) atom and two oxygen (O) atoms. Each oxygen atom shares a double bond with the central carbon atom, resulting in a stable molecular structure.

Covalent bonding involves the sharing of electrons between atoms to achieve a stable electron configuration. In the case of carbon dioxide, each oxygen atom shares four electrons with the carbon atom, and the carbon atom shares four electrons overall with the two oxygen atoms.

The answer is Number of protons

Two atoms that are different isotopes of the same element have same number of protons.

What are elements?

Element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.Each element has atoms which are unique to itself.

A muffin has a mass of 100g and a volume of 500cm3. What the density of the muffin? Show all work

Answers

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.

Why do we get hot when we exercise?

Answers

It’s your body’s way of regulating your core temperature, preventing you from overheating. Your muscles heat up as they expend energy during exertion. When this happens, your skin begins to sweat, causing your body to cool down. The spike in your body heat also alerts your brain to ensure your body remains at the normal core temperature of 98.6 degrees Fahrenheit (or 37 degrees Celsius).
While exercising the body begins to warm up. When the body begins to warm up our muscles convert stored energy into heat energy, making our bodies become warmer. As the body heats up further the brains thermostat ensures that you remain close to the normal core temperature.

How does the electro negativity difference between atoms determine the type of bond they will form

Answers

The absolute value of the difference in electronegativity (ΔEN) of two bonded atoms provides a rough measure of the polarity to be expected in the bond and, thus, the bond type. When the difference is very small or zero, the bond is covalent and nonpolar. When it is large, the bond is polar covalent or ionic.

what mass of calcium chloride will be produced from 3.750 moles of hcl reacting with ca(oh)2

Answers

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

Rank the following atoms in order of increasing first ionization energies (i.e., lowest to highest): Rb, F, Mg, B, N.

Answers

Answer:

see the pic for the answer

Taking into account the definition of ionization energy, the atoms in order of increasing first ionization energies will be: Rb, Mg, B, N, F

Electrons are held in atoms by their attraction to the nucleus, which means that energy is needed to remove an electron from the atom.

Ionization energy, also called ionization potential, is the necessary energy that must be supplied to a neutral, gaseous, ground-state atom to remove an electron from an atom. When an electron is removed from a neutral atom, a cation with a charge equal to +1 is formed.

The further away the electron is from the nucleus, the easier it is to remove it, that is, the less energy is needed.

In a group, the ionization energy increases upwards because when passing from one element to the bottom, it contains one more layer of electrons. Therefore, the valence layer electrons, being further away from the nucleus, will be less attracted to it and it will cost less energy to remove them.

In the same period, in general, it increases as you shift to the right. This is because the elements in this way have a tendency to gain electrons and therefore it will cost much more to tear them off than those on the left which, having few electrons in the last layer will cost them much less to lose them.

This can be summed up by saying that the ionization energy is minimal for alkali metals that have a single electron outside a full layer. It usually increases in each row of the periodic table, with the maximum in the noble gases that have complete layers.

Taking into account the above in mind, the atoms in order of increasing first ionization energies will be: Rb, Mg, B, N, F

Answers

Answer:

C₃H₈ + 5 O₂ ⇒ 3 CO₂ + 4 H₂O

2 C₃H₈ + 10 O₂ ⇒ 6 CO₂ + 8 H₂O

Explanation:

The combustion reaction is when propane reacts to oxygen to form a compound of carbon and water. If the product of carbon is carbon dioxide, the combustion is called complete. Let's considered the unbalanced combustion reaction.

(Note: I assume is C₃H₈, propane, because C₃H₁₈ doesn´t exist).

C₃H₈ + O₂ ⇒ CO₂ + H₂O

We will start balancing C and H that are just in 1 compound on each side, and finally we will balance O atoms. One way to do so is:

C₃H₈ + 5 O₂ ⇒ 3 CO₂ + 4 H₂O

We can get a different way of balancing the equation if we, for instance, multiply all the stoichiometric coefficients by 2.

2 C₃H₈ + 10 O₂ ⇒ 6 CO₂ + 8 H₂O
