Answer:
It has to be weak vander waal's forces of attraction.
Answer:
The tail and the rings are held together by the force of gravity.
How do the force factors compare to the products of the masses?
Answer:
The force factors are equal to the first numbers of the products of the masses in scientific notation.
Explanation:
Ex. 1.0 x 10^5 kg^2 then the force factor would be 1.
ex. 3.0 x 10^12 kg^2 then the force factor would be 3.
To solve this we must be knowing each and every concept related to scientific notation and its calculations. Therefore, in scientific notation, the force factors seem to be equivalent to the first digits of the masses' products.
What is scientific notation?Mathematics is a way of representing numbers using a decimal number ranging from one to 10, but not 10 multiplied by a factor of 10. The most common type of mathematical notation is All numbers in scientific notation are expressed in the generic form N 10m.
In scientific notation, the force factors seem to be equivalent to the first digits of the masses' products.
Example1 1.0 x 10⁵ kg² , force factor is 1.
Example2 3.0 x 10¹² kg² ,force factor is 3.
Therefore, in scientific notation, the force factors seem to be equivalent to the first digits of the masses' products.

For your 13th answer in #4, what is the other name for this particle?
Answer:
The First layer is the troposphere. The troposphere is what we live in. It creates weather for us. Second layer is the Stratosphere. You will find the ozone layer in it. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Life as we know it wouldn't be possible without this layer of protection. Third layer is Mesosphere. The Mesosphere is very important for earth's protection. The mesosphere burns up most meteors and asteroids before they are able to reach the earth's surface. Fourth layer is Thermosphere. The Thermosphere absorbs the sun radiation making it very hot.
Explanation: I don't know if you include this one but the fifth layer is the Exosphere. Although the exosphere is the most distance layer of earth's atmosphere it is the layer that is the planet's first line of defense against the sun's rays. It is also the first layer to come into contact and protect the earth from meteors, asteroids, and cosmic rays.
Answer:
Explanation:
The really interesting characteristic of the atmosphere is that each layer has a different temperature range. That is truly incredible when you list them.
The first layer is the troposphere. It is the layer closest to the earth's surface. It is 12 km high and goes from 15oC to - 56oC
The next layer is the Stratosphere. It is 38 km above the Troposphere and the temperature goes from -56 to -2.5
The third layer is Mesosphere. It is 40 km above the Stratosphere and the temperature goes from -2.5 to -86.5
The next layer is the Thermosphere. It is 710 km above the Mesosphere. It goes from - 86.5 to 1200o C So this goes from - 100 roughly to + 1200. That is a massive distance. It speaks wonders of how balanced this planet really is.
The final layer is the Exosphere. It goes up to 3000 km. The temperature is consistently at 1200oC
What I don't understand is how you get the layers from a 13 answer of something. What is the first name of the particle? That would seem to have nothing to do with this answer. Please explain because this was a good deal of work that might be for nothing. Mind you the answer is very interesting.

In which material would the particles be closest together?
O Syrup
O Brick
O Air
O Water
Answer:
Brick
Explanation:
The distance between particles is best determined by density. So, to find which material has the most compacted particles, we need to find which material has the highest density. Solids will always have the highest densities, so Brick would have the particles that are closest together.

Answer:
C
Explanation:
There is a mixture of three gases. We know the total pressure is 2.50 atmosphere and the pressure of the oxygen and the nitrogen in the mixture are 0.52 atmosphere and 0.84 atmosphere. The jar containing the gases has a volume of 25.0 liters and is at a temperature of 32 degrees Celsius. What are the pressure and the number of moles of carbon dioxide in the container?
Answer:
1.14 atm and 1.139 mol
Explanation:
The total pressure of the container is equal to the sum of the partial pressure of the three gasses:
P = Poxygen + Pnitrogen + Pcarbon dioxide2.50 atm = 0.52 + 0.84 + Pcarbon dioxideNow we solve for the pressure of carbon dioxide:
Pcarbon dioxide = 1.14 atmTo calculate the number of CO₂ moles we use PV=nRT:
P = 1.14 atmV = 25.0 Ln = ?R = 0.082 atm·L·mol⁻¹·K⁻¹T = 32 °C ⇒ 32 + 273.16 = 305.16 K1.14 atm * 25.0 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 305.16 K
n = 1.139 molWhen calculating the amount of product formed during alcohol fermentation, one mole of ethanol is chemically equivalent to what volume of CO2 (g) measured at 1 atm and 273 K
Answer:
44.8 dm^3
Explanation:
The equation for the fermentation of glucose is;
C6H12O6 -----> 2C2H5OH + 2CO2
This means that two moles of ethanol carbon dioxide are produced.
If 1 mole of gas at STP occupies 22.4 dm^3, then two moles occupies; 22.4 dm^3 × 3 = 44.8 dm^3

In a molecule of calcium sulfide, calcium has two valence electron bonds, and a sulfur atom has six valence electrons. How many lone pairs of electrons are present in the Lewis structure of calcium sulfide?
A. one
B. two
C. three
D. four
E. none
Also, state why.
There are none
Further explanationGiven
a molecule of calcium sulfide
two valence electron of Calcium(Ca)
six valence electrons of Sulfur(S)
Required
number of lone pairs of electrons
Solution
Lewis structure shows the form of bonds that occur in the valence electrons of an element or compound
Valence electrons are electrons used in a chemical bond
To achieve stability, the element S needs 2 more electrons which are obtained from 2 electrons from the Ca element,
A lone pair electron means refers to an unshared pair of electrons(not bonding to the other atoms)
This condition usually occurs in covalent bonds
As we know, the bond between Ca, which is a group 2 (metal) with Sulfur in group 16, is an ionic bond because it occurs between metal and non-metal ions, so there is no sharing of electrons, but there is a release of electrons from Ca ions to S ions to form an octet. , so all the valence electrons in S are paired

Explanation:
An object is located 360 millimeters from a converging lens. The image formed is 150 millimeters high, at a distance of 90 millimeters from the lens. What’s the height of the object?
The height of the object : 600 mm
Further explanationGiven
d object=360 mm(object distance)
d image=90 mm(image distance)
Required
h object
Solution
focal length = f :
[tex]\tt \dfrac{1}{f}=\dfrac{1}{d_o}+\dfrac{1}{d_i}\\\\\dfrac{1}{f}=\dfrac{1}{360}+\dfrac{1}{90}\rightarrow f=72~mm[/tex]
The magnification :
[tex]\tt M=\dfrac{d_i}{d_o}=\dfrac{90}{360}=0.25[/tex]
[tex]\tt M=\dfrac{h_i}{h_o}\\\\0.25=\dfrac{150}{h_o}\rightarrow h_o=600~mm[/tex]

calculate the molar mass of cacl2
Answer:
[tex]\boxed {\boxed {\sf 110.98 \ g/mol}}[/tex]
Explanation:
The molar mass is the mass of a substance in grams per mole.
To find it, add the mass of each element in the compound. These masses can be found on the Periodic Table.
The compound given is:
[tex]CaCl_2[/tex]
The compound has 1 Ca (calcium) and 2 Cl (chlorine).
Mass of Calcium
The molar mass of calcium is 40.08 g/mol There is only one atom of Calcium in CaCl₂, so the number above is what we will use.Mass of Chlorine
The molar mass of chlorine is 35.45 g/mol There are two atoms of chlorine in CaCl₂, therefore we need to multiply the molar mass by 2. 35.45 * 2= 70.9 g/molMolar Mass of CaCl₂
Now, to find the molar mass, add the molar mass of 1 calcium and 2 chlorine. 40.08 g/mol + 70.9 g/mol =110.98 g/molThe molar mass of CaCl₂ is 110.98 grams per mole.
