4. A 14.5-L balloon is in the air where it is 20.0 C at 0.980-atm. A wind passes over and the balloon's pressure becomes 740.0-mmHg and its size adjusts to 14.3-L. What Celsius temperature was the wind?
The temperature of the wind as that decreases the volume and the pressure of the balloon to the given values is 14.09°C.
What is Combined gas law?Combined gas law put together both Boyle's Law, Charles's Law, and Gay-Lussac's Law. It states that "the ratio of the product of volume and pressure and the absolute temperature of a gas is equal to a constant.
It is expressed as;
P₁V₁/T₁ = P₂V₂/T₂
Given the data in the question;
Initial volume V₁ = 14.5LInitial pressure P₁ = 0.980atmInitial temperature T₁ = 20.0°C = 293.15KFinal volume V₂ = 14.3LFinal pressure P₂ = 740.mmHg = 0.973684atmFinal temperature T₂ = ?We substitute our given values into the expression above.
P₁V₁/T₁ = P₂V₂/T₂
( 0.980atm × 14.5L )/293.15K = ( 0.973684atm × 14.3L )/T₂
14.21Latm / 293.15K = 13.92368Latm / T₂
14.21Latm × T₂ = 13.92368Latm × 293.15K
14.21Latm × T₂ = 4081.72679LatmK
T₂ = 4081.72679LatmK / 14.21Latm
T₂ = 287.24K
T₂ = 14.09°C
Therefore, the temperature of the wind as that decreases the volume and the pressure of the balloon to the given values is 14.09°C.

If we accelerate a radioactive isotope of an element in a particle accelerator to a speed close to that of light, what would its observed mass be compared to its mass at rest
When the speed of the particle is close to that of light, it's observed mass would be infinitely large.
To answer the question, we need to know what observed mass is.
What is observed mass in relativity?This is the mass the body of an object in relativistic motion appears to have.
So, observed mass, m' = m/√(1 - β²) where
m = rest mass and β = relative velocity of isotope to light.Now, since the speed of the particle is close to that of light, β ≅ 1.
So, m' = m/√(1 - β²)
m' = m/√(1 - 1²)
m' = m/√(1 - 1)
m' = m/√0
m' = m/0
m' = ∞
So, when the speed of the particle is close to that of light, it's observed mass would be infinitely large.

Answer:
#4: 0.89 mol/L #5: 0.36 mol
Explanation:
#4: Morality is Moles/ Liters
So take 3.2 mols ÷ 3.6 L = 0.8888... since there are 2 sig figs in the question the answer would round to 0.89 mol/L
#5: to find the number of moles needed, you take the mol/L and multiply that by the volume.
0.89 mol/L ×0.400L = 0.356 mols. the liters cancel out. Since 0.89 has the least number of sig figs your final answer should have 2. which it 0.36 mols.

How many grams of He are necessary to fill a balloon having a volume of 4.50 × 10^{3} mL to a pressure of 1.14 × 10^{3} torr at 25.0ºC?
The mass in grams of He are necessary to fill a balloon having a volume of 4.50×10³ mL to a pressure of 1.14×10³ torr at 25.0ºC is 1.104 grams.
How do we calculate the grams from moles?Mass (W) in grams from moles (n) will be calculated by using the below equation:
n = W/M, where
M = molar mass
Moles of helium gas will be calculated by using the ideal gas equation:
PV = nRT, where
R = universal gas constant = 62.363 L.torr / K.mol
P = pressure of gas = 1.14×10³ torr
V = volume of gas = 4.50×10³ mL = 4.50 L
n = moles of gas = ?
T = temperature = 25.0ºC = 298 K
On putting these values on the ideal gas equation, we get
n = (1140)(4.5) / (62.363)(298) = 5130 / 18584
n = 0.276 moles
Now we convert this moles into mass by using the first equation as:
W = (0.276mol)(4g/mol) = 1.104 g
Hence required mass of helium gas is 1.104 grams.

Briefly explain the source, harmful effects and physical properties of oxides of
nitrogen.
Answer:
Nitrogen reacts with oxygen to form a number of nitrogen oxides. It exhibits different oxidation states in its oxides, ranging from +1 to +5. Oxides of nitrogen having nitrogen in the higher oxidation state are more acidic than that in lower oxidation state. Nitrogen oxides are critical components of photochemical smog. They produce the yellowish-brown colour of the smog. In poorly ventilated situations, indoor domestic appliances such as gas stoves and gas or wood heaters can be significant sources of nitrogen oxides.
Following are the harmful effects caused by the oxides of nitrogen
Nitrogen oxides causes irritation in mucous membrane.
Large concentrations of Nitrogen oxide causes lungs problems in humans
It causes injuries to vegetation by damaging leaves.
Nitrogen oxide oxidizes Hydrocarbons in the presence of sunlight, which causes eye irritation, asthama attacks, nasal and throat infections.

B. The gas molecules possess kinetic energy.
C. The gas molecules interact with one another.
D. The gas molecules exert pressure on a container.

Answer: the gas molecules interact with one another
Explanation:
According to the forces of attraction, the gas molecules interacting with one another makes a gas non - ideal.
What are forces of attraction?Forces of attraction is a force by which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.

Why can you calculate the total pressure of a mixture of gases by adding together the partial pres-
sures of the component gases?
Answer:
Dalton's law of partial pressure
Explanation:
In Dalton's law of partial pressure is states that the total pressure of a gas mixture is equal to the sum of the partial pressures of the component gasses.
This is the equation: [tex]P_{total} =P_{gas 1} +P_{gas2} + P_{gas3}[/tex].. so on and so forth.
basically what Dalton is saying partial pressures are just fractions of the total pressure, think of it as if you cut 12 slices of pizza and 12 people grabbed a slice of the pizza. Each person has 1/12 of that pizza, 1/12 x 12 = 1.
let's say there is a container filled with nitrogen gas (N) , hydrogen gas (H), and ammonia gas (NH₃).
N= 40 atm
H=20 atm
NH₃= 10 atm
you would plug this information into this equation: [tex]P_{total} =P_{gas 1} +P_{gas2} + P_{gas3}[/tex]
[tex]P_{N} + P_{H} + P_{NH{3}} = P_{total}[/tex]
[tex]P_{40} + P_{20} + P_{10} = 70[/tex]
N is 40/70 of the gaseous mixture.
H is 20/70 of the gaseous mixture.
NH₃ is 10/70 of the gaseous mixture.
if you add these fractions up:
[tex]\frac{40}{70} +\frac{20}{70} +\frac{10}{70} =\frac{1}{1} =1[/tex]

Answer:
-65 kJ
Explanation:
To use Hess's Law, you need to combine the equations in a way that results in the desired equation. To add reactants/products, just add the equations and their subsequent heat of reactions. Subtracting reactants/products involves flipping the signs of enthalpies, duplicating reactants/products involves multiplying the coefficients and enthalpies by a desired number.
A + 2B --> C + D
+ B --> 2C + D
------------------------------------
A + 3B --> 3C + 3D
In this case, you only need to add the equations together to get the desired equation. Because you just add the equations, combine each equations' heat of reaction.
(-20 kJ) + (-45 kJ) = -65 kJ
The overall heat of reaction of the desired reaction is -65 kJ.

23.7 g/mol
44.0 g/mol
58.5 g/mol
82.3 g/mol
Answer: 44.0 g/mol
Explanation:
[tex]M=m.RT/PV[/tex]
M=1.211*0.082*296/ 0.987*0.677
M= 44 g/mol
A gas collected from a reaction has a mass of 1.211 g and occupies a volume of 0.677 L. The temperature in the laboratory is 296 K, and the air pressure is 0.987 atm the molar mass of the gas 23.7 g/mol. option A is correct.
What is gas law?The universal gas law given by Boyle, Charles , Avogadro and Gauss known as combined gas law with respect to temperature, volume and pressure using universal gas constant and number of moles.
According to universal gas equation or combined gas equation
P V = n R T
where , P = pressure
V = volume
n = number of moles
R = universal gas constant = 8.313
T = temperature
n = W / M.M
W = weight
M.M = molar mass
substituting the value in the equation
0.987 × 0.677 = 1.211 / M.M × 8.313 × 296
M.M = 23.7 g/mol
Therefore, gas collected from a reaction has a mass of 1.211 g and occupies a volume of 0.677 L. The temperature in the laboratory is 296 K, and the air pressure is 0.987 atm the molar mass of the gas 23.7 g/mol. option A is correct.

If 40.0 grams of HCI were dissolved in enough water to make a solution with a total volume of 3.0 liters, what would be the molarity of the solution?
Answer: 0.37 M
Explanation:
HCl has a gram-formula mass of 36.46 g/mol, so 40.0 g is about 40.0/36.46=1.10 mol.
This means that since molarity = (moles of solute)/(liters of solution), the answer is 1.10/3.0 = 0.37 M
