7) True. Sulfur dioxide and oxides of nitrogen are the primary pollutants responsible for acid rain.

8) False. When the base of an inversion lowers, pollutants are trapped near the ground, limiting dispersion.

9) False. The green flash phenomenon is best observed during sunset or sunrise, not around noon.

10) True. Oxides of nitrogen from automobile exhaust are a major cause of acid rain in eastern North America.

7.

True. Sulfur dioxide and oxides of nitrogen (NOx) are the primary pollutants that contribute to the formation of acid rain. When these gases are released into the atmosphere from sources like industrial processes and vehicle emissions, they can undergo chemical reactions with water vapor and other compounds to form sulfuric acid and nitric acid, respectively. These acids can then be deposited as acid rain, which has detrimental effects on the environment and ecosystems.

8.

False. When the base of an inversion lowers, it actually traps pollutants close to the ground, preventing their dispersion into a greater volume of air. Inversions occur when a layer of warm air traps cooler air beneath it, forming a stable atmospheric condition. This phenomenon is common during temperature inversions, where the air temperature increases with height instead of decreasing. Under these conditions, pollutants, including smog and other harmful substances, can become trapped near the surface and accumulate, leading to poor air quality.

9.

False. The best time of day to see the green flash phenomenon is actually during sunset or sunrise, not around noon when the sun's rays are most intense. The green flash is a rare optical phenomenon that occurs when conditions such as atmospheric refraction and dispersion cause the last glimpse of the sun to briefly appear green or blue-green at the horizon. It is most commonly observed just after the sun has set below the horizon or right before it rises.

10.

True. Oxides of nitrogen (NOx), primarily emitted from automobile exhaust, have been identified as one of the main contributors to acid rain in eastern North America. When nitrogen oxides react with other atmospheric compounds, they can form nitric acid, which contributes to the acidity of rainwater. The combustion of fossil fuels in vehicles, particularly gasoline and diesel engines, releases significant amounts of nitrogen oxides into the atmosphere, making automobile emissions a major source of these pollutants. Efforts have been made to reduce NOx emissions from vehicles to mitigate the impact of acid rain.

Answer:

m = 8.1 kg

Explanation:

Density of metal ball, d = 8.96 g/cm³

Diameter of ball, d = 12 cm

Radius of ball, r = 6 cm

Density of an object=mass/volume

The metal ball is in the shape of sphere whose volume is given by :

\(V=\dfrac{4}{3}\pi r^3\\\\V=\dfrac{4}{3}\pi (6)^3\\\\V=904.77\ cm^3\)

Now using formula,

\(m=d\times V\\\\m=8.96\ g/cm^3\times 904.77\ cm^3\\\\m=8106.73\ g\)

or

m = 8.1 kg

So, the mass of the metal ball is 8.1 kg.

Answer:

\(a = \frac{24.79078- 1.7161b}{1.310 - b}\)

\(b = 1.310 - \frac{22.5427}{a - 1.7161}\)

Explanation:

Given

\(P = 1\ atm\)

\(V = 1.310\ L\)

\(T =160\ K\)

Required

Solve for a and b

Van Der Waals equation is:

\(P = \frac{RT}{V - b} - \frac{a}{V^2}\)

Substitute values for P, V and T, we have:

\(1 = \frac{R*160}{1.310 - b} - \frac{a}{1.310^2}\)

R is a constant and the value is:

\(R = 0.0821\)

So, the equation becomes:

\(1 = \frac{0.0821*160}{1.310 - b} - \frac{a}{1.310^2}\)

Simplify the expression

\(1 = \frac{13.136}{1.310 - b} - \frac{a}{1.7161}\) ----- (a)

Solving for (a):

\(1 + \frac{13.136}{1.310 - b} = \frac{a}{1.7161}\)

Multiply both sides by 1.7161

\(a = [1 + \frac{13.136}{1.310 - b}] * 1.7161\)

Take LCM

\(a = [\frac{1.310 - b+13.136}{1.310 - b}] * 1.7161\)

Evaluate like terms

\(a = [\frac{14.446- b}{1.310 - b}] * 1.7161\)

Open bracket

\(a = [\frac{24.79078- 1.7161b}{1.310 - b}\)

Solving for (b), we have:

\(1 + \frac{13.136}{1.310 - b} = \frac{a}{1.7161}\)

Subtract 1 from both sides

\(\frac{13.136}{1.310 - b} = \frac{a}{1.7161}-1\)

Take LCM

\(\frac{13.136}{1.310 - b} = \frac{a-1.7161}{1.7161}\)

Inverse both sides

\(\frac{1.310 - b}{13.136} = \frac{1.7161}{a - 1.7161}\)

Multiply both sides by 13.136

\(1.310 - b = 13.136 * \frac{1.7161}{a - 1.7161}\)

\(1.310 - b = \frac{22.5427}{a - 1.7161}\)

Collect like terms

\(b = 1.310 - \frac{22.5427}{a - 1.7161}\)

Answer:

Geothermal provides a reliable source of energy as compared to other renewable resources such as wind and solar power. This is because the resource is always available to be tapped into, unlike with wind or solar energy.

Explanation:

Because its source is the almost unlimited amount of heat generated by the Earth's core. Even in geothermal areas dependent on a reservoir of hot water, the volume taken out can be reinjected, making it a sustainable energy source.

Answer:

A geothermal power plant gets energy from the heat deep below the surface of the earth. Shafts are drilled down, often as deep as several kilometres, one to pump water down to the hot rocks, and another nearby which will allow the heated water (or steam) to rise up. This steam is then used to spin electricity turbines to generate electricity.

Explanation:

We would need 14.52 L of gaseous hydrogen to get 1.3052g of hydrogen and 10.42 L of gaseous chlorine to have 33.50g of chlorine.

Gaseous hydrogen has a density of 0.0899 g/L at 0 ∘C, and gaseous chlorine has a density of 3.214 g/L at the same temperature. We can use the formula density = mass/volume to find the volume of each gas that we need.

For hydrogen:

0.0899 g/L = 1.3052 g / V

V = 1.3052 g / 0.0899 g/L

V = 14.52 L

So, we would need 14.52 liters of gaseous hydrogen to get 1.3052 g of hydrogen.

For chlorine:

3.214 g/L = 33.50 g / V

V = 33.50 g / 3.214 g/L

V = 10.42 L

So, we would need 10.42 liters of gaseous chlorine to get 33.50 g of chlorine.

To calculate the number of equivalents of Mg2+ in a solution, we need to divide the number of moles by 2, as each mole of Mg2+ contains 2 equivalents. In this case, the solution containing 2.50 mol of Mg2+ has 1.25 equivalents of Mg2+.

To answer this question, we need to know the definition of an equivalent. An equivalent is the amount of a substance that can combine with or replace one mole of hydrogen ions in an acid-base reaction. In the case of Mg2+, it can replace two hydrogen ions, so one equivalent of Mg2+ is equal to half a mole of Mg2+.
Given that the solution contains 2.50 mol of Mg2+, we can calculate the number of equivalents by dividing the number of moles by 2. This is because each mole of Mg2+ contains 2 equivalents, as we discussed earlier.
2.50 mol Mg2+ / 2 = 1.25 equivalents of Mg2+
Therefore, the solution that contains 2.50 mol of Mg2+ has 1.25 equivalents of Mg2+.

Answer

%Yield = 87.2%

Explanation

Given:

mass of NH3 reacted = 73 g

mass of H2O produced = 101 g

We know:

molar mass of NH3 = 17,031 g/mol

molar mass of water = 18.01528 g/mol

Required: % Yield

Solution:

The formula used to calculate the percentage yield is:

%Yield = (actual yield/theoretical yield) x 100

The actual yield of H2O produced = 101 g

Now lets calculate the theoretical yield first.

First find the number of moles of NH3, and use stoichiometry to find the theoretical mass of water.

n = m/M n is the moles, m is the mass and M is the molar mass.

n = 73/17,031 g/mol

n = 4.29 mol

Using the stoichiometry, there molar ratio between NH3 and H2O is 4:6

Therefore the moles of H2O = 4.29 x (6/4)

n of H2O = 6.43 mol

The theoretical mass can then be calculated:

m = n x M

m = 6.43 mol x 18.01528 g/mol

m = 115.83 g

%Yield = (101 g/115.83)*100

%Yield = 87.2%

To calculate the pressure of butane vapor in equilibrium with butane liquid at 298 K, we need to use the following equation:

∆G° = -RTln(K)

where:
- ∆G° = standard Gibbs free energy change of vaporization (-2.125 kJ/mol in this case)
- R = gas constant (8.314 J/mol*K)
- T = temperature (298 K)
- K = equilibrium constant for the vaporization reaction

The equilibrium constant can be expressed as the ratio of the partial pressure of the vapor to the vapor pressure of the liquid:

K = P_vapor / P_liquid

At equilibrium, the two pressures are equal, so we can simplify the equation to:

K = P / P_liquid

where P is the pressure of the butane vapor in atm.

To solve for P, we need to rearrange the equation and substitute the known values:

∆G° = -RTln(K)
-2.125 kJ/mol = -(8.314 J/mol*K)(298 K) ln(P / P_liquid)

Simplifying and converting units:

-2125 J/mol = -(2490 J/K) ln(P / 1 atm)
0.854 = ln(P / 1 atm)
P / 1 atm = e^0.854
P = 2.35 atm

Therefore, the pressure of butane vapor in equilibrium with butane liquid at 298 K is 2.35 atm.

The refrigerator would use 180 kilowatt-hours (kWh) of electric energy over the course of 30 days, assuming it runs for 12 hours each day.

To calculate the kilowatt-hours (kWh) of electric energy used by the refrigerator in 30 days, we need to multiply the power rating by the total running time.

Given:

Power rating of the refrigerator = 500 W

Running time per day = 12 hours

Number of days = 30

First, we need to convert the power rating from watts to kilowatts:

Power rating = 500 W / 1000 = 0.5 kW

Next, we calculate the total energy used in kilowatt-hours (kWh) over the 30-day period:

Energy used = Power rating × Running time × Number of days

Energy used = 0.5 kW × 12 hours/day × 30 days

Energy used = 180 kWh

The amount of concentrated solution needed is (0.286 M)(65 mL) / C M, and the amount of water needed is 65 mL minus the volume of the concentrated solution.

To calculate the molarity of Kool Aid desired, we need to determine the number of moles of Kool Aid powder and sugar in the package. Since the molecular formula for sugar is C12H22O11, we can calculate its molar mass as follows:

Molar mass of C12H22O11 = (12 * 12.01) + (22 * 1.01) + (11 * 16.00)

= 144.12 + 22.22 + 176.00

= 342.34 g/mol

Given that the package contains 4.25 grams of Kool Aid powder, we can calculate the number of moles of Kool Aid powder using its molar mass:

Number of moles of Kool Aid powder = Mass / Molar mass

= 4.25 g / 342.34 g/mol

≈ 0.0124 mol

Similarly, for the sugar, which has a molar mass of 342.34 g/mol, we can calculate the number of moles of sugar using its mass:

Number of moles of sugar = Mass / Molar mass

= 192.00 g / 342.34 g/mol

≈ 0.5612 mol

Now, to calculate the molarity of the desired Kool Aid solution, we need to determine the volume of water. Given that 1.06 quarts is equal to 1 liter, and we have 2.00 quarts of water, we can convert it to liters as follows:

Volume of water = 2.00 quarts * (1.06 liters / 1 quart)

= 2.12 liters

To find the molarity, we use the formula:

Molarity (M) = Number of moles / Volume (in liters)

Molarity of Kool Aid desired = (0.0124 mol + 0.5612 mol) / 2.12 L

≈ 0.286 M

To prepare 65 mL of the desired molarity, we can use dilution calculations. We need to determine the volume of concentrated solution and the volume of water needed.

Let's assume the concentration of the concentrated Kool Aid solution is C M. Using the dilution formula:

(C1)(V1) = (C2)(V2)where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.

Given that C1 = C M and V1 = V mL, and we want to prepare a final volume of 65 mL (V2 = 65 mL) with a final concentration of 0.286 M (C2 = 0.286 M), we can rearrange the formula to solve for the volume of the concentrated solution:

(C M)(V mL) = (0.286 M)(65 mL)

V mL = (0.286 M)(65 mL) / C M

So, the amount of concentrated solution needed is (0.286 M)(65 mL) / C M, and the amount of water needed is 65 mL minus the volume of the concentrated solution.
