Consider the following reaction, the equilibrium constant for this reaction at 298 is 0.113: 2NO2(g) = N2048) A) You have a system with 5.00 atm of NO2 and 7.00 atm of N204, is this reaction at equilibrium? Calculate Q to support your answer. 9.5 B) Which way will the reaction proceed to reach equilibrium? In C) Using the value of K, calculate the value for AGº. D) Complete an ICE diagram to find the equilibrium pressures of the two gases. E) Are the products or the reactants favored at equilibrium? Support your answer with 2 pieces of evidence from this question.
Answers
a. The reaction is not at equilibrium
b. The reaction will shift to the left to reach equilibrium.
c. The value for AGº is -22.7 kJ/mol.
d. The preasure at equilibrium are P(NO₂) = 2.96 atm
P(N₂O₄) = 8.02 atm
e. The products are favored at equilibrium.
A) To determine if the reaction is at equilibrium, we need to calculate the reaction quotient Q and compare it to the equilibrium constant K. The expression for Q is Q = (P(N₂O₄))² / P(NO₂)², where P is the partial pressure of each gas.
Plugging in the given values, we get Q = (7.00 atm)² / (5.00 atm)² = 1.96. Since Q is greater than K, the reaction is not at equilibrium.
B) Since Q is greater than K, the reaction will shift to the left (towards the reactants) to reach equilibrium.
C) The relationship between the equilibrium constant K and the standard free energy change ΔG° is given by the equation ΔG° = -RTln(K), where R is the gas constant (8.314 J/mol·K) and T is the temperature in Kelvin (298 K). Plugging in the given values, we get ΔG° = -(8.314 J/mol·K)(298 K)ln(0.113) ≈ -22.7 kJ/mol.
D) An ICE table for the reaction is:
2NO₂(g) ⇌ N₂O₄(g)
I 5.00 atm 7.00 atm
C -2x +x
E 5.00 - 2x 7.00 + x
At equilibrium, Q = K, so we can set up an equation using the expression for Q:
K = (P(N₂O₄))² / P(NO₂)²
0.113 = (7.00 + x)² / (5.00 - 2x)²
Solving for x, we get x ≈ 1.02 atm. Substituting this value into the expressions for the equilibrium pressures in the ICE table, we get:
P(NO₂) = 5.00 - 2x ≈ 2.96 atm
P(N₂O₄) = 7.00 + x ≈ 8.02 atm
E) The equilibrium constant K = 0.113 indicates that the products (N₂O₄) are favored at equilibrium. Two pieces of evidence that support this conclusion are:
The value of Q calculated in part A is greater than K, indicating that there are relatively more products than would be present at equilibrium.
In the ICE table, the equilibrium partial pressure of N₂O₄ is greater than the initial partial pressure, while the equilibrium partial pressure of NO₂ is less than the initial partial pressure. This suggests that the reaction has shifted towards the products, indicating that the products are favored at equilibrium.

The half-life of a first-order reaction is 30.0 seconds. what is the rate constant k for the reaction?
Answers
The rate constant of the first-order half-life reaction is 0.023 / sec or ln(2)/30 sec.
The formula for a first-order half-life reaction is t = (1/k) [ ln (initial concentration/final concentration)].
For determining the rate constant k, we can easily substitute the given t=30.0s to the formula. As for the initial and final concentration, we will be using 1/2 of the initial concentration as the final concentration. With this, the ratio of initial and final concentration would be equal to 1/(1/2) or 2. The exact value of the concentration is not important for this problem.
t= (1/k) * ln(2)
30.0 seconds = (1/k) * ln(2)
k = (ln (2)) / 30 seconds
k = ln (2) / 30 or 0.023/sec

Answers
The half-life of the radioactive sample is approximately 3.5 hours. To find the half-life of the radioactive sample, We can use the following steps:
1. Determine the initial and final counts per minute (CPM): initially 6320 CPM and after 10.5 hours, 382 CPM.
2. Calculate the decay ratio: final CPM / initial CPM = 382 / 6320 ≈ 0.06044.
3. Use the decay formula: \(N_{t}\)= \(N_{0}\) * \(1/2^{T/t}\), where \(N_{t}\) is the final CPM, \(N_{0}\) is the initial CPM, t is the time elapsed (10.5 hours), and T is the half-life.
4. Rearrange the formula to solve for T: T = t *㏒(1/2) / ㏒( \(N_{t}\)/ \(N_{0}\)).
5. Plug in the values: T = 10.5 * ㏒(0.5) / ㏒(0.06044) ≈ 3.5 hours.

Answers
Answer:
The percentage yield is 79.12%
Explanation:
The first thing we need to calculate here is the theoretical yield of ethyl ethanoate that can be obtained from 20g of ethanol.
Since the mole ratio is 1:1, then this is quite straightforward.
What we need to obtain at first here is the number of theoretical moles of ethanol reacting.
That would be mass of ethanol/molar mass of ethanol
Molar mass of ethanol is 46g/mol
Thus the number of moles is 20/46 = 0.4348 mole
Like it is indicated earlier, since the number of moles are equal from the balanced equation, it also means that 0.4348 mole of ethylethanoate is produced
Now, we need to know the mass of ethyl ethanoate produced
The mass can be calculated by multiplying the number of moles by the molar mass
The molar mass of ethyl ethanoate is 88g/mol
So the mass of it produced = 0.4348 * 88 = 38.2624 or let’s just say 38.26
Thus, the percentage yield will be;
Actual yield/Theoretical yield * 100%
From the question, our actual yield is 30.27g while our calculated theoretical yield is 38.26g
= 30.27/38.26 * 100% = 79.12%

Entrenched poverty and the lack of development are persistent characteristics of the globaleconomy.Which theoretical perspective provides the most compelling reasons for these issues and what should be done to address these issues?
Answers
The structuralism perspective provides the most compelling reasons for entrenched poverty and lack of development in the global economy. According to structuralism, these issues are deeply rooted in the structural inequalities and power imbalances inherent in the global economic system.
Structuralists argue that the global economy is characterized by unequal distribution of resources, unequal access to markets, and asymmetrical power relations between developed and developing countries. These structural barriers perpetuate poverty and hinder development by limiting the ability of less developed countries to participate fully and benefit from the global economic system.
To address these issues, structuralists advocate for structural changes in the global economic system, including:
Addressing Trade Inequalities:

A sample of Zn(s) is reacted with HCl(aq) to form hydrogen gas. The H2 gas bubbles out of aqueous solution and is collected in a 660 mL container at 411 Torr and 25. 0 C. How many grams of zinc reacted?
Answers
The mass of zinc that reacted is 0.480 g.
To determine the mass of zinc that reacted, we need to use the ideal gas law to calculate the number of moles of hydrogen gas produced in the reaction. We can then use the stoichiometry of the balanced chemical equation to find the number of moles of zinc that reacted, and convert that to grams using the molar mass of zinc.
The balanced chemical equation for the reaction of zinc with hydrochloric acid is:
Zn(s) + 2HCl(aq) → \(ZnCl_2(aq) + H_2(g)\)
From the equation, we can see that one mole of zinc reacts with two moles of hydrochloric acid to produce one mole of hydrogen gas.
First, we need to calculate the number of moles of hydrogen gas that was produced. We can use the ideal gas law to do this:
PV = nRT
where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature.
We need to convert the pressure and volume to units that are consistent with the gas constant R, which has units of L·atm/mol·K. The given pressure of 411 Torr is equivalent to 0.541 atm, and the volume of the container is 660 mL, or 0.66 L. The temperature is given as 25.0°C, or 298.2 K.
Plugging in the values, we get:
(0.541 atm) (0.66 L) = n (0.0821 L·atm/mol·K) (298.2 K)
Solving for n, we get:
n = 0.0147 mol \(H_2\)
Since the stoichiometry of the balanced chemical equation tells us that one mole of zinc reacts with one-half mole of hydrogen gas, the number of moles of zinc that reacted is half of the number of moles of hydrogen gas:
n(Zn) = 0.5 × n(\(H_2\)) = 0.00735 mol Zn
Finally, we can convert the moles of zinc to grams using the molar mass of zinc, which is 65.38 g/mol:
m(Zn) = n(Zn) × M(Zn) = 0.00735 mol × 65.38 g/mol = 0.480 g Zn
Therefore, the mass of zinc that reacted is 0.480 g.

The amount by which substance gets heated up is directly proportional to the current passing through it. As more current is passed through the battery it gets heated more.
During heating, the iron present in the steel wool reacts with oxygen to form iron oxide with iron present in the+3 oxidation state.When the heat exceeds a certain point the steel wool catches fire due to the heat generated.

Draw the product of the aldol-dehydration reaction with diethylketone and p-tolualdehyde. (one
Answers
The aldol reaction involves the condensation of an enolizable aldehyde or ketone with an electrophile. In the presence of a base, the electrophile attacks the carbonyl carbon, forming an alkoxide intermediate.
The alkoxide ion then abstracts a proton from an alpha-carbon, forming an enolate ion. The enolate ion is a nucleophile and can attack an electrophile, resulting in a new carbon-carbon bond.
In the case of the aldol-dehydration reaction, the product of the aldol reaction is further dehydrated to form an α,β-unsaturated carbonyl compound. This is achieved by removing a molecule of water from the aldol product. The removal of water is often facilitated by heating the reaction mixture, which drives off the water as a gas.
In the specific case of the reaction of diethylketone and p-tolualdehyde, the aldol reaction leads to the formation of a β-hydroxy ketone intermediate. This intermediate then undergoes dehydration to give a product that contains an α,β-unsaturated ketone.
In conclusion, the aldol-dehydration reaction is a powerful tool for the formation of new carbon-carbon bonds. By carefully selecting the starting materials and reaction conditions, a wide variety of α,β-unsaturated carbonyl compounds can be synthesized.

Energy in the amount of 420 J is added to a 35 g sample of water at a temperature of 10°C. What is the final temperature of the water?
Answers
The final temperature of the water, T2 = 38.57°C
Temperature can be defined as a measure of the degree of hotness or coldness of a physical object (body). Thus, it is measured with a thermometer and its units are degree Celsius (°C), Fahrenheit (°F) and Kelvin (°K).
A calorie refers to the amount of heat required to raise the temperature of a gram of water by one (1) degree Celsius (1°C).
Given the following data:
Quantity of energy = 420JMass = 35 gramsInitial temperature, T1 = 10°CThe specific heat capacity of water is 4.2 J/g°C.
To find the final temperature of the water (T2):
Mathematically, the quantity of energy (heat capacity) is given by the formula;
\(Q = mcdt\)
Where;
Q represents the heat capacity or quantity of heat.M represents the mass of an object.C represents the specific heat capacity of water.dt represents the change in temperature.Substituting the values into the formula, we have;
\(420 = 3.5 \; * \; 4.2 \; * \; dt\)
\(420 = 14.7 \; * \; dt\\\\dt = \frac{420}{14.7}\)
Change in temperature, dt = 28.57°C
Next, we would solve for the final temperature by using this formula;
\(dt = T2 - T1\)
\(28.57 = T_{2} - 10\\\\T_{2} = 28.57 \; + \; 10\\\\T_{2} = 38.57\)
Final temperature, T2 = 38.57°C
Therefore, the final temperature of the water, T2 is equal to 38.57°C
