The concentration of HI at equilibrium is 0.138 M. The correct answer is option A.

To find the concentration of HI at equilibrium, we need to use the equilibrium constant expression and the stoichiometry of the reaction.

The equilibrium constant expression is:

Kc = [H2][I2]/[HI]^2

We are given that Kc = 0.0156, and we can assume that the reaction is at equilibrium, which means that the concentrations of H2, I2, and HI are not changing anymore.

Let x be the concentration of H2 and I2 at equilibrium (since they have the same concentration), and let y be the concentration of HI at equilibrium.

Then, from the stoichiometry of the reaction, we can write:

[H2] = x
[I2] = x
[HI] = 0.550 - y

Substituting these values into the equilibrium constant expression, we get:

0.0156 = x^2/(0.550 - y)^2

Taking the square root of both sides and solving for x, we get:

x = 0.0700 M

Substituting this value back into the expressions for [H2] and [I2], we get:

[H2] = [I2] = 0.0700 M

Finally, substituting these values and the value of [HI] into the equation for the total volume of the reaction vessel, we get:

2.00 L = (0.0700 M + 0.0700 M + 0.550 - y)V

Solving for y, we get:

y = 0.138 M

Therefore, 0.138 M is the concentration of HI at equilibrium, which corresponds to answer choice A.

c. Carbon dioxide is not a criteria pollutant. The criteria pollutants are a group of six common air pollutants that are regulated by the United States Environmental Protection Agency (EPA) because of their potential harm to human health and the environment.

The six criteria pollutants are: Carbon monoxide (CO)

Sulfur dioxide (SO2)

Nitrogen oxides (NOx)

Ozone (O3)

Particulate matter (PM)

Lead (Pb)

Carbon dioxide (CO2) is not considered a criteria pollutant because it is not directly harmful to human health at typical ambient concentrations. However, CO2 is a greenhouse gas and contributes to climate change, which is a significant environmental concern. The EPA regulates CO2 emissions from certain sources, such as power plants and vehicles, but it is not considered a criteria pollutant.

The six criteria pollutants were identified by the EPA as being common in outdoor air and having the potential to harm human health and the environment. Here is a brief description of each of the criteria pollutants:

Carbon monoxide (CO): This is a colorless, odorless gas that is produced by the incomplete combustion of fuels such as gasoline, oil, and wood. High levels of CO can be harmful to human health, causing headaches, dizziness, nausea, and even death.

Sulfur dioxide (SO2): This is a gas that is produced by the burning of fossil fuels that contain sulfur, such as coal and oil. SO2 can cause respiratory problems in humans, particularly in people with asthma or other lung conditions. It can also harm plants and animals, and contribute to acid rain.

Nitrogen oxides (NOx): These are gases that are produced by combustion, particularly in vehicles and power plants. NOx can cause respiratory problems and contribute to the formation of ground-level ozone (smog), which can harm human health and the environment.

Ozone (O3): This is a gas that is formed when NOx and volatile organic compounds (VOCs) react in the presence of sunlight. Ozone can cause respiratory problems, particularly in people with asthma or other lung conditions. It can also harm plants and animals, and contribute to acid rain.

Particulate matter (PM): This refers to tiny particles that are suspended in the air, such as dust, dirt, and soot. PM can cause respiratory problems, particularly in people with asthma or other lung conditions. It can also harm the cardiovascular system and contribute to premature death.

Lead (Pb): This is a toxic metal that was once widely used in gasoline and other products. Lead can harm the nervous system and cause developmental problems, particularly in children.

The EPA regulates emissions of these pollutants from a variety of sources, such as power plants, vehicles, and industrial facilities. The goal is to reduce levels of these pollutants in the air to protect human health and the environment. The EPA sets National Ambient Air Quality Standards (NAAQS) for each of the criteria pollutants, which are the maximum allowable concentrations in the air. States are responsible for implementing plans to meet these standards.

To calculate the Ecell value at 298K for the given cell, we need to use the Nernst equation,

Ecell = E°cell - (RT/nF) ln(Q), Ecell is the cell potential Ecell, he standard cell potential E°cell, gas constant (8.314 J/mol·K) is R, temperature in Kelvin (298 K) is T, number of electrons transferred in the reaction (2 in this case) is n, Faraday constant (96,485 C/mol) is F and reaction quotient is Q.

First, let's find the value of Q. The reaction quotient for this cell is,

Q = [Cu²⁺][Ag]² / [Ag⁺]²

Substituting the given concentrations,

Q = (0.000900)(0.00475)² / (0.00475)²

Q = 0.000900

Next, let's find the standard cell potential, E°cell. We can look this up in a table of standard reduction potentials. The half-reactions for this cell are,

Cu²⁺(aq) + 2e⁻ → Cu(s) E°red = +0.34 V

Ag⁺(aq) + e⁻ → Ag(s) E°red = +0.80 V

To get the overall reaction, we need to reverse the first half-reaction and multiply it by 2,

Cu(s) → Cu²⁺(aq) + 2e⁻ E°red = -0.34 V

2Ag⁺(aq) + 2e⁻ → 2Ag(s) E°red = +0.80 V

Adding these two half-reactions gives the overall reaction,

Cu(s) + 2Ag⁺(aq) → Cu²⁺(aq) + 2Ag(s) E°cell = +0.46 V

Now we can use the Nernst equation to calculate the cell potential at 298K,

Ecell = E°cell - (RT/nF) ln(Q)

Ecell = 0.46 - (8.314 × 298 / (2 × 96,485)) ln(0.000900)

Ecell = 0.46 - (0.0257) ln(0.000900)

Ecell = 0.46 - (-0.0349)

Ecell = 0.495 V

The two conditions that can cause water or liquids to backflow into a water system are back siphonage and back pressure. Option (d) is the correct answer.

Back siphonage occurs when there is a sudden decrease in water pressure in the water supply system, causing the water to flow in the opposite direction, leading to backflow. This can happen when there is a break in the main water supply line, or when there is a sudden high demand for water, such as during firefighting activities. Backpressure, on the other hand, occurs when the pressure in the downstream water system is higher than the pressure in the upstream water system.

This can happen when a pump is connected directly to a potable water system without proper backflow prevention devices or when a boiler or other heating device is connected to a water system without proper safety valves.

Explanation:

We can use the Ideal Gas Law to solve for the number of moles of gas present:

PV = nRT

where:

P = pressure (in atm)

V = volume (in L)

n = number of moles

R = ideal gas constant (0.08206 L·atm/mol·K)

T = temperature (in Kelvin)

First, we need to convert the temperature from Celsius to Kelvin:

T = 25ºC + 273.15 = 298.15K
