Answer: 1.56 ATM
Explanation: if we assume temperature is constant, gas obeys
Boyles law pV= constant. Then p1·V1= p2·V2. And V1 = p2V2/p1
= 3.0 atm·0,52 l / 1.0 atm
The initial or original volume of the gas with pressure increased to the given value is 1.56L.
Boyle's lawBoyle's law states that "the volume V of a given quantity of gas is inversely proportional to its pressure P as long as temperature remains constant.
It is expressed as;
P₁V₁ = P₂V₂
Given the data in the question;
Initial pressure P₁ = 1.0atmFinal pressure P₂ = 3.0atmFinal volume V₂ = 0.52LInitial Volume V₁ = ?To determine the initial volume of the gas, we substitute our given values into the expression above.
P₁V₁ = P₂V₂
V₁ = P₂V₂ / P₁
V₁ = ( 3.0atm × 0.52L ) / 1.0atm
V₁ = 1.56Latm / 1.0atm
V₁ = 1.56L
Therefore, the initial or original volume of the gas with pressure increased to the given value is 1.56L.

How many liters of hydrogen gas is produced at 298 K and 0.940 atm if 4.00 moles of hydrochloric acid react with an excess of magnesium metal?
O 26.0 liters
O 52.1 liters
82.3 liters
104 liters
Answer:
74.04 liters of hydrogen gas are produced.
Explanation: According to reaction, 2 mol of HCl gas gives 1 mole of hydrogen gas, then 6 moles of HCl gas will give: moles of hydrogen gas that is 3 moles.
The pressure of the hydrogen gas at 298 K = 0.990 atm
The volume occupied by the hydrogen gas = V
Number of hydrogen has moles = 3 moles
PV=nRT
V = 74.04 L
74.04 liters of hydrogen gas are produced.
Answer:
38.2 liters Is the answer

4.2 L of a gas has a pressure of 560mmHg at 72⁰F. What is the temperature at760mmHg if the volume is still 4.2 L? (5 pts)
Answer:
The temperature at 760mmHg if the volume is still 4.2 L is 400.862 K
Explanation:
Gay Lussac's law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. This law can be expressed mathematically as follows:
[tex]\frac{P}{T} =k[/tex]
Having an initial state 1 and a final state 2, the following is true:
[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]
In this case:
P1= 560 mmHgT1= 72 F= 295.372 K (being 32 F= 273.15 K)P2= 760 mmHgT2= ?Replacing:
[tex]\frac{560 mmHg}{295.372 K} =\frac{760 mmHg}{T2}[/tex]
Solving:
[tex]T2= 760 mmHg*\frac{295.372 K}{560 mmHg}[/tex]
T2= 400.862 K

1) The ionic compound below is soluble in water. Complete the following:
-Draw the interaction of the ionic compound and water in the proper orientation. 3pts
-On the line below discuss the strength of the interaction within the compound compared to the strength of interaction
between the compound and water.
Answer:
The hydrogens of the water molecules around the bromide ion will need to be faced toward it, whereas the oxygens of the water molecules around the potassium ion will need to be faced toward it.
The strength of the interaction within the compound will supersede that of the interaction between the compound and water.
Explanation:
To answer this question, you need to be aware of the structure of a water molecule and its components. A water molecule has the chemical formula of H2O, and oxygen is inherently electronegative, meaning that it attracts electrons very strongly. As a result, when it is in H2O, it pulls the valence electrons of the H atoms very strongly, which results in the H atoms being partially positively charged and the O atom being partially negatively charged. Therefore, the O atom is going to be attracted to the potassium ion, whereas the H atom is going to be attracted to the bromide ion.
The answer to the second part of the question is as written above because ionic bonds are stronger than ion-dipole bonds; that's just the way it is.

Explain why silk was not the ideal material for hot air balloons.
Answer:
Cost of silk was too high
Explanation:
The major reason of not using silk as a fabric in the hot air balloons was high cost of silk. Due to its high cost, silk became unaffordable for use in modern balloon.
If cost is neglected, then silk is the perfect material for hot air balloon as it is light in weight

Identify at least three control variables that could be used with this investigation: What temperature allows for bacterial growth to occur quickly?
Answer:
Time allowed for incubation, size of the dish, the amount of light, amount of agar, the type of agar…etc
Explanation:
We define a control variable as any variable that has to be held constant during a study.
If i wish to study what temperature allows for bacterial growth to occur quickly, i will have to subject different bacterial cultures to different temperatures.
The variables that must remain the same across all these cultures at different temperatures is what we call the control variables. They ensure that the results of the study are reliable.

When chlorine reacts with potassium bromide, chlorine displaces bromine.
Cl2 + 2 KBr → Bra + 2 KCI
Explain why chlorine is more reactive than bromine.
Answer:
Chlorine is more reactive than bromine because the chlorine atom has fewer shells and the electronic bonding is much stronger. The electrons are closer to the nucleus, therefore it is easier for chlorine to attract and hold electrons in its outer shell forming stronger bonds with other atoms.
(As you go down Group 7/the Halogens - they get less reactive)
Chlorine has two stable isotopes, C1 and C If Cl has a mass of approximately 34.97 and Cl has a mass of approximately 3697 what percent abundances are each found in?
Answer:
%C₁ = %C₂ = 50%
Explanation:
Set up simultaneous equations to solve for two unknowns,
let f₁ and f₂ = fractional abundances of C₁ and C₂ respectively.
Then f₁ + f₂ = 1.00 and
34.97f₁ + 36.97f₂ = Wt. Avg. Atomic Mass (amu) = (34.97 + 36.97)/2 = 35.97amu
Solve equation 1 for f₂ = 1 - f₁ and substitute into equation 2
=> 34.97f₁ + 36.97(1 - f₁) = 35.97
=> 34.97f₁ + 36.97 - 36.97f₁ = 35.97
=> 2f₁ = 1
=> f₁ = 1/2 = 0.50 => 50% abundance for C₁
=> f₂ = 1 - 0.50 = 0.50 => 50% abundance for C₂
Arrange these atoms and ions in order of decreasing radius:
K+ Ar Cl-
Answer:
Cl- > Ar > K+
Explanation:
Due to the fact that they have different nuclear charges, it means their radius will be different.
Now, the positive charge (cation) with the greater charge value will possess a smaller radius due to the fact that its electrons will have greater attraction to its nucleus.
So, the lesser the value of the charge, the larger the radius.
In the question, K+ has the highest value of charge and thus the smallest radius while Cl- has the lowest value of charge and thus the largest radius. So the correct order in decreasing size is;
Cl- > Ar > K+

Explanation:
What volume will 1,27 moles of helium gas occupy at 63°C and 75.2 kPa?
Answer:
47.34L
Explanation:
Using the general gas equation as follows:
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,
V = ?
P = 75.2 kPa = 75.2 × 0.00987 = 0.74atm
T = 63°C = 63 + 273 = 336K
n = 1.27mol
Using PV = nRT
V = nRT/P
V = 1.27 × 0.0821 × 336 ÷ 0.74
V = 35.034 ÷ 0.74
V = 47.34L

2. What evidence is there that mass extinction events occurred?
Answer: Although the best-known cause of a mass extinction is the asteroid impact that killed off the non-avian dinosaurs, in fact, volcanic activity seems to have wreaked much more havoc on Earth's biota. Volcanic activity is implicated in at least four mass extinctions, while an asteroid is a suspect in just one. Examples, of mass extinctions are Permian extinction of marine species, and Cretaceous extinction of various species, including dinosaurs.
