Answer:
Gravity helps show a cause and effect by demostarting how one object will have an effect on another object.
Explanation:
If you bounce a ball, it will fly back up, but it will fall down again because of gravity. The cause is GRAVITY and the effect is the ball FALLINg. Now, because o fgravity, when the ball bounces up again, it will only bounce 1/2 the hieght, having another cause and effect. As gravity pushes down on objects, the more an object is effected by it, the more presure it will have.

5. Predict which element would have a higher electron affinity: silicon or arsenic. Support your prediction with an explanation.
Answer:
Silicone
Explanation:
According to periodic trends, electron affinity increases as you go right and decreases as you go down. Silicone is above arsenic so I would expect it to have a higher electron affinity.

What type of weathering creates a granite Tor?
Physical or
Chemical or
Biological
Answer:
Physical
Explanation:
Physical weathering is defined as the geological process in which rocks are broken down but there is no change in their chemical composition.
Granite tor are the rock masses above the ground surface which are associated with granites
Granite Tor is an example of physical weathering as they formed by freeze–thaw weathering. Granite tor are formed when magma present in the crust cools down and form batholith. Rocks above batholith gets erodes and left the batholith to expose.
Hence, the correct answer is "Physical weathering'.

how many atoms of helium are required to equalise the
mass of a silver atom ?
The atoms of helium are required to equalize the mass of a silver atom is 8.4 x 10 ⁻⁴⁸.
What are atoms?Atoms are the minute particles that are present inside elements.
Atomic mass of silver is 107.86 g/mol
Mass of one atom of silver will be
[tex]\dfrac{ 107.86 }{6.022 \times 10^{-23}} = 1.79 \times 10^2^4[/tex]
Atomic mass of helium is 6.941
[tex]\dfrac{6.022 \times 10^{-23}}{4.0 \times 1.79 \times 10^2^4 } = 8.4 \times 10^{-48}[/tex]

Which structures join with the cell’s membrane during exocytosis?
Answer:Exocytosis is also used to integrate new proteins into the cell membrane. In this process, the new protein is formed inside the cell, and migrates to phospholipid bilayer of the vesicle. The vesicle, containing the new protein as a part of the phospholipid bilayer, fuses with the cell membrane.

How could you prepare 100 ml of a 0.40 mol/L of MgSO4 solution from a stock solution of 2.0 mol/L MgSO4. And then how would u prepare it?
Answer:
C1V1=C2V2
C1 is 2.0mol/l
V1=?
C2=.4mol/L
V2=100ml or for this 0.1L

Which statement best compares the melting points of magnesium and sodium?
a
Magnesium has a higher melting point because it contributes one additional electron per atom than sodium in the electron sea.
b
Sodium has a higher melting point because it contributes one fewer electron per atom than magnesium in the electron sea.
c
Sodium has a higher melting point because it contributes two fewer electrons per atom than magnesium in the electron sea.
d
Magnesium has a higher melting point because it contributes two additional electrons per atom than sodium in the electron sea.
A because according to electron sea theory magnesium shares two valence electrons in electron sea while sodium shares one suggesting that magnesium has stronger metallic bond than sodium so breaking metallic bond in magnesium will require more energy as compared to breaking metallic bond in sodium
The melting point of magnesium is higher than the melting point of sodium because it contributes two additional electrons per atom than sodium in the electron sea. Thus option d is correct.
What is melting point?Melting point of a substance is the temperature at which it converts from solid state to liquid state where, the two phases are in equilibrium. Melting point is affected by the bond type, molecular weight, temperature and pressure.
Melting point of elements increases along a period because the atomic size is decreasing along the period and molecular weight is increasing. Thus, the nuclear attractive pull increases resulting in higher energy needed to break the attractive force.
Magnesium is 12th element and sodium is 11th element. Thus magnesium is smaller than sodium and have one more electron than sodium. Thus magnesium have high molecular weight and high nuclear attraction leads to its higher melting point.

Explanation:
When a plate moves it shifts the earth, and it can cause an earthquake.
A fault is where two of earth's tectonic plates come together. They can slide against the other, causing earthquakes, they can push against each other causing mountains to form, and they can move apart from each other, causing valleys or trenches.

You're leaving a carnival and you're pumped because a clown just handed you a red, helium- filled balloon. But then, something tragic occurs. You hear the ice cream truck, jump with joy doing a 180 degrees in the air, and you lose grip of your beautiful balloon. Upward it flies as you stare speechless into the sky. Why did this helium balloon fly away instead of falling to the ground like a balloon filled with your breath usually does?
How many carbon atoms are there in a 12.5 kg sample of carbon?
step by step solution
Answer:
6.27 X 10^26 atoms
Explanation:
Write down the formula:
number of moles = mass/Ar (Ar is atomic mass)
Ar of carbon = 12
mass = 12.5kg or 12500g
Substitue these values into the formula:
number of moles = 12,500g / 12 = 3125/3 or 1041.6
Convert this to atoms:
1 mole = 6.022 X 10^23 atoms
So, 1041.6 moles = 6.27 X 10^26 atoms

What is an element ?A chemical element is a species of atoms, including the pure substance made entirely of that species, that have a specific number of protons in their nuclei. Chemical elements, in contrast to chemical compounds, cannot be reduced by any chemical process into simpler molecules.
They can be identified by their particular atomic number. The periodic table groups the elements according to their atomic number and draws attention to those with related qualities.
The most vital ingredient for life is carbon. Life as we know it would not exist without this element. You'll see that carbon is the main component of the chemicals required for life.

The question is incomplete, the complete question is;
Which of these best describes the relationship between the inner core, outer core, mantle, crust, asthenosphere, and lithosphere?
A: The coolest layers are farthest from the core.
B: The least dense layers are closest to the core.
C: The layers with the highest concentration of metals are closest to the crust.
D: The layers that remain in a molten state are closest to the crust.
Answer:
The coolest layers are farthest from the core.
Explanation:
When we talk about the internal structure of Earth, we mean the subdivisions of the solid Earth, that is, the concentric spherical layers that marks out the structure of the solid Earth.
The inner core is the innermost part of the earth's core and is known to have extremely high temperature. This high temperature steadily decreases as you approach the earth's surface.
Hence, the coolest layers are farthest from the core.

how many mongo seed are equal to 3.50 moles of mongo seeds?
answer:
2.107 x 10^24 mongo seeds
Answer:
50 moles of many mango seeds = 2.107.10²⁴ mango
Further explanation
A mole is a unit of many particles (atoms, molecules, ions) where 1 mole is the number of particles contained in a substance that is the same amount as many atoms in 12 gr C-12
While the number of moles can also be obtained by dividing the mass (in grams) with the molar mass of element or molecule
With Avogadro's number
N = number of gas particles
No = Avogadro number (6.02.10²³)
n = number of moles
n= N/No
3.50 moles of many mango seeds are comparable to
N mango seeds= 3.5 x 6.02.10²³
N mango seeds=2.107 x 10²⁴..
How many pounds of ice are required to absorb 4900 kJ of heat as the ice melts? The heat of fusion of water is 0.334 kJ/g.
Answer:
m = 32.34 pounds of ice.
Explanation:
In this case we need to use the following expression of heat:
q = m * ΔHf (1)
Where:
q: heat absorbed in J or kJ
m: mass of the compound in g
ΔHf: heat of fusion of the water in kJ/g
We are asked to look for the mass of ice in pounds, so after we get the grams, we need to convert the grams to pounds, using the following conversion:
1 pound --------> 453.59 g (2)
So, we have the heat and heat of fusion, from (1) let's solve for the mass, and then, using (2) the conversion to pounds:
q = m * ΔHf
m = q / ΔHf
m = 4900 / 0.334 = 14,670.66 g of ice
Now, the conversion to pounds:
m = 14,670.66 g * 1 pound/453.59 g
m = 32.34 pounds of ice.Hope this helps
