Claim 1
Explanation:
I chose this claim because I believe that when the plates under the earth move or shift, that's what causes an earthquake and when everything starts to shake. If it was the other way around there wouldn't be any reason for an earthquake to start.
hope that helped :)
Answer:
Plates move, which can cause earthquakes.
Explanation:
Tectonic plates are always slowly moving, however sometimes they can "lock" together, creating pressure and build up. The release of this energy results in a Tectonic earthquake. Therefore, the movement of plates causes earthquakes.

same.
B. It shows that the mass of the products is greater than the mass of
the reactants when a reaction increases the moles of substances.
O C. It shows that the mass of the reactants is greater than the mass
of the products when gases are produced by the reaction.
O D. It shows that the number of each type of atom stays the same.

4. There are 1.9 moles of Oxygen gas at a pressure of 3.50 atm, and the temperature is 65°C. What is the
volume of the gas? Remember that R = 0.0821 L x atm/Kx mol AND that you must convert °C to K.
Fill in the variables chart:
Answers
Answer:
15.06 L
Explanation:
Using the ideal gas law equation:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information provided in this question,
P = 3.50 atm
n = 1.9 moles
V = ?
T = 65°C = 65 + 273 = 338K
Using PV = nRT
V = nRT/P
V = (1.9 × 0.0821 × 338) ÷ (3.5)
V = 52.725 ÷ 3.5
V = 15.06 L
Organize the following list of elements from highest to lowest Ionization Energy:
Phosphorus, Bismuth, Arsenic, Antimony, Nitrogen
Answers
Answer: The list of elements from highest to lowest Ionization Energy is Nitrogen > Phosphorus > Arsenic > Antimony > Bismuth.
Explanation:
The amount of energy required to remove the most loosely bound electron from an isolated gaseous atom or ion is called ionization energy.
Element with a half-filled orbital requires much more energy to remove an electron. This is because element with a half-filled electronic configuration is the most stable in nature.
More stable or tightly electrons are bound to the nucleus of an atom more will be its ionization energy. This also means that smaller is the atom higher will be its ionization energy.
When we move from top to bottom in a group the size of atom increases and the attraction between nucleus of atom and its valence electrons decreases. Hence, less will be the ionization energy.
Therefore, ionization energy decreases on moving down a group.
So, the given elements Phosphorus, Bismuth, Arsenic, Antimony, Nitrogen are all group 15 elements. Hence, decreasing order of their ionization energy is as follows.
Nitrogen > Phosphorus > Arsenic > Antimony > Bismuth
Thus, we can conclude that the list of elements from highest to lowest Ionization Energy is Nitrogen > Phosphorus > Arsenic > Antimony > Bismuth.

A) 15
B) 16
C) 17
D) 18
Answers
Answer:
16
Explanation:
Metals in group 2 form ions of the sort M^2+. If they must form ionic compounds of general formula MX, then the non metal (X) must have a valency of 2 and form the ion X^2-.
Among the options listed, only elements of group 16 form ions of the sort X^2-, hence they are able to form compounds of general formula MX with group 2 cations. Examples of such compounds include; CaS, MgS etc

Explain in terms of structure and bonding why carbon dioxide has a low boiling point and calcium carbide has a high boiling point
Answers
Answer:
See explanation
Explanation:
Let us consider the two compounds carefully. Carbon dioxide is purely a non-polar molecular compound while the bond between the C2^2- ion and Ca^2+ is ionic thereby making CaC2 an ionic compound.
Recall that ionic compounds have high melting and boiling points due to strong ionic interactions in the structure of the compound.
On the other hand, CO2 is a non-polar substance whose molecules are held together only by weak dispersion forces.
As a result of the reasons outlined above, carbon dioxide has a low boiling point and calcium carbide has a high boiling point.

The saturation point for a solution is 250 grams of solute per 500 grams of solvent. If you pour 500 grams of
solute into 800. grams of solvent, how many grams of solute are in solution? 3-digit answer only
Answers
Answer: 400 g of solute is present in the solution
Explanation:
A solution consists of solute and solvent. A solute is defined as the component that is present in a smaller proportion and solvent is defined as the component that is present in a larger proportion.
Saturation point of a solution is defined as the point after which the solution becomes saturated. This simply means no more solute can be added to the solution.
Mass of solvent = 800 g
At saturation point, 500 g of solvent can dissolve 250 g of solute
Applying unitary method:
800 g of solvent will dissolve = [tex]\frac{250g}{500g}\times 800g=400g[/tex] of solute
Hence, 400 g of solute is present in the solution.

If you have 3 moles of gas at a pressure of 2.5 atmospheres and a volume of 8 liters, what is the temperature? Pay attention to the unit of pressure used.
Answers
Answer:
-191.7°C
Explanation:
P . V = n . R . T
That's the Ideal Gases Law. It can be useful to solve the question.
We replace data:
2.5 atm . 8 L = 3 mol . 0.082 L.atm/mol.K . T°
(2.5 atm . 8 L) / (3 mol . 0.082 L.atm/mol.K) = T°
T° = 81.3 K
We convert T° from K to C°
81.3K - 273 = -191.7°C
Answer:
The temperature is 81.3 K.
Explanation:
An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
The pressure, P, the temperature, T, and the volume, V, of an ideal gas, are related by a simple formula called the ideal gas law:
P*V = n*R*T
where P is the gas pressure, V is the volume that occupies, T is its temperature, R is the ideal gas constant, and n is the number of moles of the gas. The universal constant of ideal gases R has the same value for all gaseous substances.
In this case:
P= 2.5 atmV= 8 Ln=3 molesR= 0.082 [tex]\frac{atm*L}{mol*K}[/tex]T= ?Replacing:
2.5 atm* 8 L= 3 moles* 0.082 [tex]\frac{atm*L}{mol*K}[/tex] *T
Solving:
[tex]T=\frac{2.5 atm* 8 L}{3 moles* 0.082\frac{atm*L}{mol*K}}[/tex]
T= 81.3 K
The temperature is 81.3 K.
At a particular temperature and [A]0 = 2.00 x 10-2 Molar, concentration versus time data were collected for this reaction and a plot of ln[A]t versus time resulted in a straight line with a slope value of -2.97 x 10-2 min-1.

If aluminum carbide is the limiting reactant, how many moles of the excess reactant are left over
a
37.3 mol
b
4.68 mol
c
7.33 mol
d
131.94 mol
Answers
Answer: 4.999 moles of excess reactant will be left over.
Explanation:
Limiting reagent is defined as the reagent which is completely consumed in the reaction and limits the formation of the product.
Excess reagent is defined as the reagent which is left behind after the completion of the reaction.
The number of moles is defined as the ratio of the mass of a substance to its molar mass.
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex] .....(1)
Given mass of aluminium carbide = 112 g
Molar mass of aluminium carbide = 143.96 g/mol
Putting values in equation 1:
[tex]\text{Moles of aluminium carbide}=\frac{112g}{143.96g/mol}=0.778mol[/tex]
For the given chemical reaction:
[tex]2Al_4C_3(s)+12H_2O(l)\rightarrow 3CH_4(g)+4Al(OH)_3(s)[/tex]
By the stoichiometry of the reaction:
2 moles of aluminium carbide reacts with 12 moles of water
So, 0.778 moles of aluminium carbide will react with = [tex]\frac{12}{2}\times 0.778=4.668 mol[/tex] of water
Given mass of water = 174 g
Molar mass of water = 18 g/mol
Putting values in equation 1:
[tex]\text{Moles of water}=\frac{174g}{18g/mol}=9.667mol[/tex]
Moles of excess reactant (water) left = 9.667 - 4.668 = 4.999 moles
Hence, 4.999 moles of excess reactant will be left over.
