a sample of br2(g) takes 14.0 min to effuse through a membrane. how long would it take the same number of moles of ar(g) to effuse through the same membrane?
A sample of [tex]Br_2[/tex](g) takes 14.0 min to diffuse out through a membrane. It would take 7 min for the same number of moles of Ar(g) to effuse through the same membrane.
According to Graham's Law of Diffusion, it is known that the rate of diffusion of a gas is proportional to the reciprocal of the square root of the molar mass of the gas. The rate of diffusion is recorded under the same pressure and temperature conditions.
It can be written as [tex]\frac{r_1}{r_2}[/tex] ∝ [tex]\sqrt\frac{m_2}{m_1}[/tex]
where [tex]r_1[/tex] is the rate of diffusion of one of the gas
[tex]r_2[/tex] is the rate of diffusion of the second gas
[tex]r_1[/tex] is the molar mass of one of the gas
[tex]m_2[/tex] is the molar mass of the second gas
According to the question,
[tex]\frac{14}{r_2}=\sqrt\frac{160}{40}\\\frac{14}{r_2}=\sqrt\frac{4}{1} \\\\r_2 = 14\sqrt{\frac{1}{4} } = 7[/tex]

It would take approximately 7.0 minutes for the same number of moles of Ar(g) to effuse through the same membrane.
Using Graham's law of effusion, we can compare the rates of effusion for Br2(g) and Ar(g). The formula for Graham's law is:
Rate₁ / Rate₂ = √(M₂ / M₁)
Here, Rate₁ and Rate₂ are the effusion rates of the two gases, and M₁ and M₂ are their molar masses. In this case, Br2(g) is gas 1 and Ar(g) is gas 2. The molar mass of Br2 is 159.8 g/mol, and the molar mass of Ar is 39.95 g/mol.
Since we know the time it takes for Br2 to effuse, we can write:
Time₁ / Time₂ = Rate₂ / Rate₁ = √(M₁ / M₂)
Plugging in the given time and molar masses:
14.0 min / Time₂ = √(159.8 g/mol / 39.95 g/mol)
Solving for Time₂:
Time₂ = 14.0 min * √(39.95 g/mol / 159.8 g/mol) ≈ 7.0 min

tamu it is frequently necessary to perform dilutions of a stock solution in the laboratory. if you were instructed to make a 1:5 dilution of a stock solution to arrive at a final volume of 13, how much stock solution would you need to pipet?
You would need to pipette 2.6 mL of stock solution to make a 1:5 dilution with a final volume of 13 mL.
To calculate this, first note that a 1:5 dilution means that for every 1 unit of stock solution, you need to add 4 units of solvent to make a total of 5 units. This can be expressed as a ratio of stock solution to solvent as 1:4. To find the amount of stock solution needed, you can use the following equation:
(volume of stock solution) / (total volume of diluted solution) = (ratio of stock solution to solvent)Plugging in the given values, we get:
(volume of stock solution) / 13 mL = 1/5Solving for the volume of stock solution, we get:

if you are performing the following reaction using 81.3 g of the starting alcohol and 48.5 g of hydrobromic acid, what is your limiting reagent?
We can see that the hydrobromic acid is the limiting reagent because it is completely consumed when 0.599 mol of it reacts with 0.599 mol of ethanol. After the reaction is complete, there will be some excess ethanol left over.
To determine the limiting reagent, we need to compare the amount of moles of each reactant used in the reaction. We can calculate the number of moles of each reactant by dividing their mass by their molar mass. Let's assume the starting alcohol is ethanol and has a molar mass of 46.07 g/mol, and hydrobromic acid has a molar mass of 80.91 g/mol. Then we have:
Moles of ethanol = 81.3 g / 46.07 g/mol = 1.765 mol
Moles of hydrobromic acid = 48.5 g / 80.91 g/mol = 0.599 mol

The correct answer to your question is option 2, which states that a dissolution process is exothermic if the amount of energy released in bringing about solute-solute interactions is greater than the sum of the amounts of energy absorbed in overcoming crystal lattice and solvent-solvent interactions.
To understand this concept better, we need to understand what happens during the dissolution process. When a solute dissolves in a solvent, the solute particles break away from their crystal lattice structure and mix with the solvent particles. This process involves overcoming the attractive forces between the solute particles (solute-solute interactions) and the attractive forces between the solvent particles (solvent-solvent interactions). At the same time, energy is released when the solute particles interact with the solvent particles (solvent-solute interactions).
In an exothermic dissolution process, the energy released due to solvent-solute interactions is greater than the energy required to overcome the crystal lattice and solvent-solvent interactions. This means that more energy is released than absorbed, resulting in a net release of heat. This is because the attractive forces between the solute and solvent particles are stronger than the forces holding the solute particles in their crystal lattice structure.
Overall, the exothermic nature of a dissolution process depends on the balance between the energy released and absorbed during the process. By understanding the interactions between solute and solvent particles, we can predict whether a dissolution process will be exothermic or endothermic.

if the size of the zinc electrode were doubled, does the cell voltage increase, decrease or stay the same? justify your answer.
In changing the size of the zinc electrode would not impact the voltage of the cell.
If the size of the zinc electrode were doubled, the cell voltage would stay the same. This is because the voltage of a cell is dependent on the difference in potential between the two electrodes, not their size.
Doubling the size of the zinc electrode would not change the potential difference between the zinc and copper electrodes, therefore the cell voltage would remain constant.

as lactic acid accumulates, which compensatory mechanism is initially triggered to maintain acid-base balance?
When lactic acid accumulates, the compensatory mechanism initially triggered to maintain acid-base balance is the respiratory system. It increases the rate and depth of breathing to eliminate more carbon dioxide, which helps reduce acidity and restore pH balance in the body.
As lactic acid accumulates, the compensatory mechanism that is initially triggered to maintain acid-base balance is increased ventilation or hyperventilation. This is because the increased ventilation leads to a decrease in carbon dioxide (CO2) levels in the blood, which helps to offset the acidic effects of lactic acid accumulation. This is a temporary compensatory mechanism, however, as the body will eventually need to eliminate the excess lactic acid through other means such as metabolism and excretion.

The rate of the reaction is directly proportional to the stability of the carbocation intermediate, and any changes in the solvent will affect the rate of the reaction.
In an SN1 reaction, the rate-determining step is the formation of a carbocation intermediate. The stability of the carbocation intermediate affects the rate of the reaction.
In this case, if 2-propanol (isopropanol) was used instead of 2-methyl-2-propanol (t-butanol), the rate of the reaction would decrease. This is because the carbocation intermediate formed in 2-propanol is less stable compared to the one formed in t-butanol.

Yes, half the C2H2 (acetylene) can react with the given amount of O2 (oxygen) in the reactor and 7.0 mol of CO2 would be produced after half the C2H2 is used up.
To determine how many moles of CO2 (carbon dioxide) would be produced after half the C2H2 is used up, we need to first write the balanced chemical equation:
2 C2H2 + 5 O2 → 4 CO2 + 2 H2O
Given 7.0 mol of C2H2 and 1.0 mol of O2, let's find out how much C2H2 can react:
(1.0 mol O2) * (2 mol C2H2 / 5 mol O2) = 0.4 mol C2H2
Since 0.4 mol is less than half of the initial 7.0 mol of C2H2 (which is 3.5 mol), half the C2H2 can react.
Now, we'll calculate the moles of CO2 produced after half the C2H2 is used up:
(3.5 mol C2H2) * (4 mol CO2 / 2 mol C2H2) = 7.0 mol CO2
Thus, 7.0 mol of CO2 would be produced after half the C2H2 is used up, rounded to the nearest 0.1 mol.

Yes, half of the 7.0 mol of C₂H₂ can react, leaving 3.5 mol of C₂H₂ unreacted. The balanced chemical equation for the reaction is
C₂H₂ + 2.5 O₂ -> 2 CO₂ + H₂O
From the equation, we can see that 1 mol of C₂H₂ reacts with 2.5 mol of O₂ to produce 2 mol of CO₂ So, to determine how many moles of CO₂are produced when half of the C₂H₂ is used up, we need to calculate how many moles of O2 are required to react with 3.5 mol of C₂H₂.
3.5 mol C₂H₂ × (2.5 mol O / 1 mol C₂H₂) = 8.75 mol O₂
So, to react with 3.5 mol of C2H2, we need 8.75 mol of O2. Since we only have 1.0 mol of O2, we can only react with 0.4 mol of C2H2. Therefore, half of the 7.0 mol of C₂H₂, which is 3.5 mol, can react with 1.0 mol of O₂.

what might be the result if you had 6 m acetic acid rather than glacial acetic acid in the first step of the friedel-crafts reaction? there would be no effect, acetic acid is just the solvent. more product would likely have formed. less product would likely have formed. more t-butanol would have reacted.
If you had 6 M acetic acid rather than glacial acetic acid in the first step of the Friedel-Crafts reaction, less product would likely have formed.
The Friedel-Crafts reaction requires a strong Lewis acid catalyst, such as aluminum chloride (AlCl3), which reacts with the acylating agent to form a reactive electrophile. In this case, the acylating agent is acetic anhydride, which reacts with AlCl3 to form an acylium ion that can then react with the aromatic ring. However, the reaction is sensitive to the amount of water present, and the presence of excess water (which would be more likely in the case of dilute acetic acid) can lead to hydrolysis of the acylium ion and a decrease in the yield of the desired product.

Calculate the amount of copper obtained by the reaction. Was it the amount you expected? Explain.
The amount of copper obtained by the reaction depends on the amount of copper chloride reacted and the limiting reagent in the reaction.
Without information on the amounts of reactants used, it is not possible to calculate the amount of copper obtained by the reaction or compare it to the expected amount. However, if the reaction was carried out under controlled conditions and all reactants were used in the stoichiometric ratio, the amount of copper obtained should be the expected amount calculated based on the balanced chemical equation.
In order to calculate the expected amount of copper obtained, the amount of copper chloride reacted should be known, and the limiting reagent should be identified. The amount of copper obtained will be determined by the limiting reagent.

How can we separate porridge from cooked rice
We separate porridge from cooked rice using a strainer or a sieve.
Porridge and cooked rice are both similar in texture and appearance, making it difficult to separate them. One way to do it is to use a strainer or a colander with small holes. Pour the mixture of porridge and rice into the strainer or colander and let the liquid portion drain out. You can also use a cheesecloth or a muslin cloth to squeeze out the liquid while retaining the rice grains.
Another method is to use a spoon to scoop out the rice from the top, leaving the porridge at the bottom. However, this method may not be as effective as the others. Regardless of the method you choose, it is important to be gentle and patient to avoid breaking the rice grains and mixing them with the porridge.

Lila is a track and field athlete. She must complete four laps around a circular track. The track itself measures 400 meters from start to finish and the race took her 6 minutes to complete.
Which best describes her speed and velocity?
Her speed is 4. 4 m/s, and her velocity is 0 m/s.
Her speed is 1. 1 m/s, and her velocity is 0 m/s.
Her speed is 0 m/s, and her velocity is 2400 m/s.
Her speed is 4. 4 m/s, and her velocity is 4. 4 m/s
The best describes her speed and velocity is; Her speed is 4. 4 m/s, and her velocity will be 0 m/s. Option A is correct.
Lila's speed will be calculated by dividing the total distance she covered by time it took her to complete the race;
Speed = Total distance/Time
In this case, Lila will covered 4 laps, which is a total distance of 4 x 400 = 1600 meters. She completed the race in 6 minutes, which is 6 x 60 = 360 seconds. Therefore, her speed is;
Speed = 1600 meters / 360 seconds
Speed = 4.44 m/s (rounded to two decimal places)
Velocity, on the other hand, is a vector quantity that takes into account both speed and direction. Since Lila ran four laps around a circular track, she ended up at the same position where she started. However, her displacement (change in position) is zero, which means her velocity is also zero.
Hence, A. is the correct option.
