The layer of Earth which provide transfer from the white core to the lithosphere that fuels convection is the mantle.
What is the Mantle layer?A mantle can be described as a layer inside a planetary body bounded above a crust and below a core. Mantles are composed of rock or ice and are usually the largest massive layer of the planetary body.
The mantle layer of the earth is a layer of silicate rock between the crust and the outer core. The mass of the mantle of 4.01 × 10²⁴ kg which is 67% of the mass of the Earth. It's a thickness of 2,900 kilometers making up about 84% of Earth's volume.
The mantle layer is predominantly solid, but it behaves as a viscous fluid. At mid-ocean ridges, partial melting of the mantle produces oceanic crust, and at subduction zones, partial melting of the mantle produces continental crust.
The temperatures range of the mantle from 200 °C at the upper boundary with the crust to 4,000 °C at the core-mantle boundary. The convection of the mantle is a chaotic process, the mantle transfers heat that fuels convection.

In the fall, how does the high pressure area
affect the hurricane?
Answer:
Hurricanes occur when ocean water warms during the spring, summer and early fall.
Explanation:
Warm air just above the water’s surface rises. The rising warm air creates a reduction in pressure at the surface, what meteorologists call a low-pressure area. Because nearby air is at a higher pressure, it will flow into the low-pressure zone.

If you were to mass the reactants before a reaction and then mass the products after the reaction what would you expect to find and why?
pls answer fast ill give brainliest!
Answer:
No change...
Explanation:
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.

A mixture of neon and argon gases exerts a total pressure of 2.39 atm. The partial pressure of the neon alone is 1.84 atm, What is the partial pressure of the argon?
Answer:
0.55 atm
Explanation:
According to Dalton's law of partial pressures,
The total pressure is the summation of the partial pressures of individual gases in a sample of non-reactive gases.
Since Neon and Argon are noble gases, they do not react with each other. So we can apply Dalton's partial pressure law.
P total = P Ar + P Ne
2.39 atm = P Ar+ 1.84 atm
P Ar = 2.39 atm - 1.84 atm
= 0.55 atm
According to the Dalton's law of partial pressure the partial pressure of the argon is 0.55 atm.
What is pressure?Pressure is defined as the force applied on an object perpendicular to it's surface per unit area over which it is distributed.Gauge pressure is a pressure which is related with the ambient pressure.
There are various units by which pressure is expressed most of which are derived units which are obtained from unit of force divided by unit of area . The SI unit of pressure is pascal .
It is a scalar quantity which is related to the vector area element with a normal force acting on it.It is distributed over solid boundaries and across arbitary sections of fluid normal to the boundaries at every point.
In this case, pressure of gas argon is obtained by subtracting pressure of gas neon from the total pressure ,that is 2.39-1.84=0.55 atmosphere.
Thus ,the partial pressure of gas argon in atmosphere is 0.55 atmosphere.

Elements in which the d-sublevel is being filled have the properties of;
transition metals.
In quantum theory the sublevel is an energy level. Now, the d-sublevel in atomic configuration has 5 orbitals and as such can contain a maximum of 10 electrons.
Now, this d-sublevel is used primarily by elements called "transition elements" as they are also called d-block elements.
However, these transition elements are also called transition metals because all the transition elements possess properties of metals generally.

A container has 1.50 moles of hydrofluoric acid molecules, a deadly acid that
can kill someone in minutes. How many molecules is this?
A container has 1.50 moles of hydrofluoric acid molecules, a deadly acid that can kill someone in minutes molecules are 9.03 × 10 ²³ molecules.
What are moles?Moles are the smallest unit of a molecule that participates in the formation of the molecules to compete in a reaction and the value will be equal to the Avogadro number 2.303 × 10 ²³.
To calculate the total number of molecules the value of one mole is 2.303 × 10 ²³. so, for 1.50 moles of hydrofluoric acid will be,
1.50 moles = 2.303 × 10 ²³.moles
hydrofluoric acid molecules = 1.50 × 2.303 × 10 ²³
hydrofluoric acid molecules = 9.03 × 10 ²³ molecules.
Therefore, 9.03 × 10 ²³ molecules are present in the container has 1.50 moles of hydrofluoric acid molecules, a deadly acid that can kill someone.

6. Haydee prepared a solution with 3mL of potassium chloride (KCl) in 200 mL of water is prepared. Calculate the percent by volume concentration of the solution.
A. 1.46% B.1.48 %
C. 1.49 % D. 1.50%
Considering the definition of percent by volume concentration, the correct answer is option D: the percent by volume concentration of the solution is 1.50%
Percent by volume concentration is a measure of concentration that indicates the volume of solute per 100 volume units of the solution. This value is calculated by dividing the volume of the solute by the total volume of the solution, and multiplying by 100 to express it as a percentage:
[tex]percent by volume concentration=\frac{volume of solute}{total volume of the solution}x100[/tex]
In this case, you know:
volume of solute= 3 mLtotal volume of the solution= 200 mLReplacing in the definition of percent by volume concentration:
[tex]percent by volume concentration=\frac{3 mL}{200 mL}x100[/tex]
Solving:
percent by volume concentration=0.015×100
percent by volume concentration=1.50
Finally, the correct answer is option D: the percent by volume concentration of the solution is 1.50%

NEED HELP ASAP! Write a statement explaining your claim about whether or not the equation is correctly balanced.
Then, provide evidence that supports your claim about whether or not the equation is correctly
balanced. Next, connect your evidence to your claim about the equation.
Answer:
I think that it it correctly balanced that is my opinion and, because the way it is set up, that the answer will tell you weather or not it is correctly balanced or not.
Evaluating the number of atoms of each element on the product and reactant side, we can conclude that the student's equation isn't balanced.
Given the chemical reaction :
[tex] Al_{4}C_{3} + 6H_{2}O ---> 3CH_{4} + 4Al(OH)_{3} [/tex]
For a balanced equation, the number of atoms of each element in the product side must be equal to that on the reactant side.
Number of hydrogen :
Reactant side = (6 × 2) = 12
Product side = (6 × 2) + (6 × 2) = 12 + 24 = 24
Product side ≠ reactant side ; Hence, the equation isn't balanced
The balanced equation for the reaction goes thus :
[tex] Al_{4}C_{3} + 12H_{2}O ---> 3CH_{4} + 4Al(OH)_{3} [/tex]
Reactant side :
Al = 4
H = (12 × 2) = 24
O = 12
C = 3
Product side :
H = (6 × 2) + (6 × 2) = 12 + 24 = 24
Al = 4
O = 4 × 3 = 12
C = 3
Therefore, the student's equation isn't balanced, the balanced version of the equation has been given .

Why do planets orbit faster as they get closer to the Sun?
The orbit becomes smaller closer to the Sun.
The orbit becomes smaller closer to the Sun.
The eccentricity changes as the planet gets closer to the Sun.
The eccentricity changes as the planet gets closer to the Sun.
The force of gravity increases closer to the Sun.
The force of gravity increases closer to the Sun.
The Sun's magnetism causes a "sling shot" effect.
Explanation:
The speed at which a planet orbits the Sun changes depending upon how far it is from the Sun. When a planet is closer to the Sun the Sun’s gravitational pull is stronger, so the planet moves faster. When a planet is further away from the sun the Sun’s gravitational pull is weaker, so the planet moves slower in its orbit.
