As depth increases, the density of the layers decreases.
Thanks.Hope it helps.The statement, that describes the thickness, top density, and bottom density of the different layers of the Earth is "as depth increases, the density of the layers decreases."
What is density layers of Earth?The density of the Earth's inner layers determines their order. The densest layer is the solid metal inner core, the mantle is of intermediate density, and the lithosphere, particularly the continental lithosphere, is the least dense layer.
Pressure rises as you go deeper. Mass/volume = density. As a result, as the volume drops, so does the density. Because of pressure, the strata beneath us become extremely dense. As a result, as the depth of the earth increases, so does the density.
Hence the correct answer is as depth increases, the density of the layers decreases.

Answers
Answer:
[tex]\boxed {\boxed {\sf 0.5 \ moles}}[/tex]
Explanation:
At standard temperature and pressure (STP), 1 mole of any gas has a volume of 22.4 liters. This applies to oxygen, so let's create a proportion.
[tex]\frac {1 \ mol}{22.4 \ L}[/tex]
Since we are trying to find the moles in 11.2 liters, we should multiply by that number.
[tex]11.2 \ L *\frac {1 \ mol}{22.4 \ L}\\[/tex]
The units of liters cancel.
[tex]11.2 *\frac {1 \ mol}{22.4 }[/tex]
Condense into 1 fraction.
[tex]\frac {11.2 }{22.4 } \ mol[/tex]
[tex]0.5 \ mol[/tex]
At STP, 11.2 liters of oxygen gas is equal to 0.5 moles of oxygen gas.

1.5 billion plastic bottles are bought world-wide each day. These bottles are about 9.8 inches in length (1 meter = 3.28 ft). If the Earth's diameter is about 40,000 km at the equator, how many times could you encircle the Earth with the bottles laid end to end?
Hint: Your DA table should have 5 conversion factors
Answers
The number of times 1.5 billion plastic bottles laid end to end could encircle the Earth would be 9.34 times.
Dimensional analysisSize of bottle = 9.8 inches
1 foot = 12 inches
Size of 9.8 inches bottles in foot = 0.8167 ft
Also, 3.28 ft = 1 meter
0.8167 ft = 0.8167x1/3.28
= 0.2490 meter
1000 meter = 1 km
0.2490 meter = 0.2490/1000
= 0.000249 km
Total number of bottles = 1.5 billion
Total length of 1.5 billion bottles laid end to end in kilometers = 1,500,000,000 x 0.000249 = 373,500 km
Number of times the bottle could encircle the earth = 373,500/40000
= 9.34 times
Thus, 1.5 billion plastic bottles would encircle the Earth about 9.34 times if laid end to end.

Answers
Answer:
C. a. 3-ethylpentane is a required answer
3-ethylpentane is the name of compound in diagram C. Therefore, the correct option is A.
An organic compound that belongs to the alkane family is 3-ethylpentane. It has an ethyl group [tex](-C_2H_5)[/tex] attached to the third carbon atom and is made up of a chain of five carbon atoms (pentane). 2,2-dimethylbutane is the formal IUPAC designation for 3-ethylpentane.
3-Ethylpentane is an alkane that demonstrates the typical properties of this group of substances. It is a saturated hydrocarbon, which means that there are only single bonds between the carbon atoms in it, making it a relatively inert substance. Alkanes are frequently present in petroleum and natural gas, and because to their characteristics, they form good fuels.
Therefore, the correct option is A.

If sufficient charge is passed through the circuit to produce 20 g of strontium in the molten strontium chloride cell, what quantity of berylium is expected in the berylium chloride cell
Answers
Answer:
Explanation:
Atomic weight of strontium ( Sr ) is 88 .
Atomic weight of Beryllium ( Be) is 9 .
Both are bivalent .
2 x 96500 coulomb is required to decompose 88 g of Sr .
88 g of Sr requires 2 x 96500 coulomb of charge
20 g of Sr will require 2 x 96500 x 20 / 88 coulomb of charge
coulomb of charge required = 43863.63 coulomb .
9 g of Be requires 2 x 96500 coulomb of charge
2 x 96500 coulomb of charge gives 9 g of Be
43863.63 coulomb .of charge gives 9 x 43863.63 / (2 x 96500 ) g of Be
= 2.04 g.

What mass of ammonium sulfate contains 4.43 x 1024 oxygen atoms?
Answers
Answer:
The mass of ammonium sulfate would be 8.86 x 1024 grams.
Explanation:
Ammonium sulfate is composed of four atoms of oxygen (O) and two atoms of nitrogen (N). Therefore, 4.43 x 1024 oxygen atoms would require 8.86 x 1024 grams of ammonium sulfate.
Ammonium sulfate is an inorganic compound composed of two nitrogen atoms (N) and four oxygen atoms (O). The molecular formula for ammonium sulfate is (NH4)2SO4.
This means that for every two nitrogen atoms, there are four oxygen atoms. Therefore, for 4.43 x 1024 oxygen atoms, there would be 8.86 x 1024 grams of ammonium sulfate required.

if the tank were heated to 1253 °C? (pay attention to units)
Answers
Answer:
If the tank were heated to 1253ºC, the pressure of the tank would be 40,734.41 mmHg.
Explanation:
Given that a closed tank contains pure nitrogen gas at a pressure of 855 mmHg and a temperature of 26.3ºC, to determine what the pressure would be if the tank were heated to 1253 ° C the following calculation must be performed:
26.3 = 855
1.253 = X
(1,253 x 855) / 26.3 = X
1,071,315 / 26.3 = X
40,734.41 = X
Therefore, if the tank were heated to 1253ºC, the pressure of the tank would be 40,734.41 mmHg.
Sep Obtain Information What are the Limitations to Making Progress with Engineering Better Batteries ? What progress have Battery Engineers Made?
Answers
Limitations in making progress with Engineering Better Batteries is that electric vehicles are being prevented to make progress in terms of size and range , progress which is made is solid state batteries.
What are solid state batteries?
A solid-state battery is a battery technology that uses solid electrodes and a solid electrolyte, instead of the liquid or polymer gel electrolytes which are found in lithium-ion or lithium polymer batteries.
While solid electrolytes were first discovered in the 19th century, several drawbacks have prevented it's widespread application. Developments in the late 20th and early 21st century have caused renewed interest in solid-state battery technologies, especially in the context of electric vehicles, starting in the 2010s.
Solid-state batteries can provide potential solutions for many problems of liquid Li-ion batteries, such as flammability, limited voltage, unstable solid-electrolyte interphase formation, poor cycling performance and strength.
