Explanation:
Which layer or layers of Earth provide the heat and energy that fuels convection?
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.

The reaction of aluminum with chlorine gas is shown.
2Al+3Cl2⟶2AlCl3
How many units of aluminum chloride (AlCl3) can be produced from 30 aluminum atoms?
number of AlCl3 units: _________________
The number of units of aluminum chloride (AlCl₃) that can be produced from 30 atoms of aluminum (Al) is 30 units
The balanced equation for the reaction is given below:
2Al + 3Cl₂ — > 2AlCl₃
From the balanced equation above,
2 atoms of Al reacted to produce 2 units of AlCl₃.
With the above information, we can determine the number of units of AlCl₃ that can be produced by the reaction of 30 atoms of Al. This can be obtained as follow:
From the balanced equation above,
2 atoms of Al reacted to produce 2 units of AlCl₃.
Therefore,
30 atoms of Al will also react to produce 30 units of AlCl₃.
Thus, 30 units of AlCl₃ were obtained from the reaction.

Leaving a Copper penny in vinegar until it turns green
Explanation:
the others are physical changes. when copper penny is put in vinegar, a reactive oixde layer is formed which is green in colour. namely, Cu(II) acetate.
The green growing on the penny of copper and the rust forming on the nail of iron are chemical changes. Boiling away salt water, scraping iron filings from a mixture of sand with a magnet, and breaking a rock with a hammer, are physical changes.

under what circumstances can an atom emit a photon
Answer:
Here
Explanation:
When the atom absorbs energy, it can move to a higher energy state, or excited state. Under what circumstances can an atom emit a photon? A photon is emitted when an atom moves from an excited state to its ground state or to a lower-energy excited state.
A sunflower turns toward the sun to absorb the greatest amount of energy. What type
of behavior is this?
A Dormancy
B Phototropism
C Hibernation
D Gravitropism
Answser:
This sunflower must be a young one because a sunflower turns toward the sun when they are young. Once they mature they will prematurally stay facing east. with this knowledge we can exclude some of tghe answers and leave the correct one remaining. It is not C becasue sunflowers do not hibernate. They lay dormante in the winter waiting for their seeds to pop out during the spring. it is not D becasue Gravitropism is a form of facing towards or away from the pull of gravity. It is nopt A because it is to simalir to Hidernation. Dormancy is staying dormant during cool temputure and ect. So our answer must be B because Phototropism is the condition that a plant growes toward light. this is why bannanas are curved and why trees grow up. So your your answer is B Phototropism.
14. A gas in a 400 ml flask exerts pressure of 81.0 kPa at 25.0°C. If the gas
was in a 250 ml container at a pressure of 101 kPa, the temperature would be
a) - 124 °C
b) - 41.2°C
c) 20.0°C
d) 232 °C
Answer: B would be the correct answer
Explanation: You will need to use P1V1/T1=P2V2/T2
So
P1= 81.0kPa /101 =0.799atm
V1=0.4L
T1=25.0C +273.15K= 298.15K
P2= 101kPa /101 = 1atm
V2=0.25L
T2= ?
T2=P2V2T1/P1V1
(1.0atm)(0.25L)(298.15K)/(0.799atm)(0.4L) =233.22K-273.15=-39.92C
how do you determine the thermal energy of an object
Answer:
An object's thermal energy is dependent upon its temperature and mass. The higher the temperature of a given quantity of a substance, more is its thermal energy. Similarly, for the same temperature, higher mass of a substance will contain more thermal energy

In a population, exponential growth
can lead to a lack of resources,
which causes the population
numbers to decline. This is an
example of:
A. a positive feedback loop
B. a negative feedback loop
C. the first law of thermodynamics
D. the second law of thermodynamics
о
Exponential growth can lead to decreasing the population size, which represents an example of a NEGATIVE feedback loop. This control mechanism (negative feedback) is common in nature.
Negative feedback is a homeostatic self-regulatory process by which the output of a given system is fed back in order to reduce its internal fluctuations.
In a negative feedback, an amplified output from the system (e.g., in this case, a sudden increased population size) leads to its self-inhibition.
This control mechanism (negative feedback loop) helps to maintain the homeostatic balance of the entire system in order to reach a set point.

Element X has two isotopes. One has a mass of 45.0 amu and is 45.0% abundant. The other has a mass of 47.0 amu and is 55.0% abundant. What is the average atomic mass of element X?*
0 46.1 amu
O 36.5 amu
0 43.8 amu
0 48.9 amu
The average atomic mass of element X that has two isotopes (one of 45.0 amu mass and 45% abundance and the other of 47.0 amu mass and 55.0% abundance) is 46.1 amu (option 1).
The average atomic mass (A) of element X can be calculated as follows:
[tex] A = m_{1}\%_{1} + m_{1}\%_{1} [/tex] (1)
Where:
m₁: is the mass of isotope 1 = 45.0 amu
m₂: is the mass of isotope 2 = 47.0 amu
%₁: is the abundance percent of isotope 1 = 45.0 %
%₂: is the abundance percent of isotope 1 = 55.0 %
Hence, the average atomic mass is (eq 1):
[tex] A = m_{1}\%_{1} + m_{1}\%_{1} = 45.0 amu*45.0\% + 47.0 amu*55.0\% = 45.0 amu*0.45 + 47.0 amu*0.55 = 46.1 amu [/tex]
Therefore, the average atomic mass of element X is 46.1 amu (option 1).

what does the theory of plate tetonics state
Answer:
Plate tetonics theory is the idea that different tectonic plates, are constantly moving and changing the surface of our Earth. They can move in three ways, convergent, divergent, and transform. Seafloor Spreading is like an example of divergent movement. When the plates diverge from each other it can create various changes such as creating a new sea floor. You can use seafloor spreading as an example of the plate tetonics theory.

Answer:
1. Ar, Cl, Al, Mg, Na
2. O, S, Se, Te, Po
Explanation:
Just remember the trends. From left to right, atomic radius decreases because proton increases and pulls electrons closer. From top to bottom, atomic radius increases because there are more electron shells.
The mass lost by the positive electron should equal the mass gained by the negative electrode suggest two reasons why the results were not expected.
Answer:
The gain in mass by the negative electrode is the same as the loss in mass by the positive electrode. So the copper deposited on the negative electrode must be the same copper ions that are lost from the positive electrode.
