Answer: At a pressure of 15.613 atm a 5.32 mol [tex]Cl_{2}[/tex] sample occupy 5.08 L at 181.59 K.
Explanation:
Given: Moles = 5.32 mol
Volume = 5.08 L
Temperature = 181.59 K
Formula used to calculate the pressure is as follows.
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the values into above formula as follows.
[tex]PV = nRT\\P \times 5.08 L = 5.32 mol \times 0.0821 L atm/mol K \times 181.59 K\\P = \frac{5.32 mol \times 0.0821 L atm/mol K \times 181.59 K}{5.08 L}\\= 15.613 atm[/tex]
Thus, we can conclude that at a pressure of 15.613 atm a 5.32 mol [tex]Cl_{2}[/tex] sample occupy 5.08 L at 181.59 K.
A substance has a pH of 4. Is it an acid or a base?
Helpppooo give answer thanks
Answer:
625 mL
Explanation:
From the question given above, the following data were obtained:
Volume of stock solution (V₁) = 250 mL
Molarity of stock solution (M₁) = 5 M
Molarity of diluted solution (M₂) = 2 M
Volume of diluted solution (V₂) =?
The volume of the diluted solution can be obtained by using the dilution formula as illustrated below:
M₁V₁ = M₂V₂
5 × 250 = 2 × V₂
1250 = 2 × V₂
Divide both side by 2
V₂ = 1250 / 2
V₂ = 625 mL
Therefore, the volume of the diluted solution is 625 mL.

14. Simply, explain the role of both the nucleus and the ribosome in protein synthesis.
Answer:
Eukaryotic cells have a true nucleus, which means the cell's DNA is surrounded by a membrane. Therefore, the nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
Ribosomes are the sites in a cell in which protein synthesis takes place. ... Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule.
Iron ore exists as Fe2O3. In order to remove the oxygen and generate pure iron, the oxygen must be transferred to another molecule. Carbon monoxide can be mixed with iron ore and carbon dioxide is generated. Carbon monoxide is produced in the combustion of carbon with limited oxygen.

Which of the following statements explains how concentration of a solution affects the rate of a reaction? (5 points)
O a
When concentration decreases, kinetic energy increases.
Ob
When concentration increases, particles collide less often.
When concentration increases, particles collide more often.
Oc
Od
When concentration decreases, collision of particles increases.
Answer:
when concentration increases, particles colide more often
The statement "When concentration increases, particles collide more often" is correct.
What is concentration?A constituent's abundance divided by the entire volume of a combination is known as concentration. Mass concentration, molar concentration, number concentration, and volume concentration are all examples of mathematical descriptions.
There are much more reactant particles travelling together as the concentration of reacting species increases. Because there would be more collisions, the reaction rate will be faster. The rate of a reaction increases as the concentration of reactants increases.

Draw the major organic product(s) of the reaction of p-bromoaniline with HNO2, HCl.
Answer:
The major product from this reaction is 4-bromobenzene diazonium chloride.
Explanation:
The reaction of p-bromoaniline with HNO2 and HCl produces diazonium salt. When primary aromatic amines are nitrosated with nitrous acid in the presence of a strong acid such as HCl, diazonium salts are frequently formed. The diazonium salts are a crucial step in the production of halides and azo compounds. The necessary reaction mechanism is depicted in the illustration in the diagram below.

Calculate the freezing point of a solution made by dissolving 13 g potassium sulfide in 150 g H2O Kf for water = 1.86 C/m
Answer:
[tex]T_F=-4.4\°C[/tex]
Explanation:
Hello there!
In this case, according to the given information, it is possible for us to calculate the freezing point of an aqueous solution of potassium sulfide by using the following equation:
[tex]T_F=T_{solv}-i*m*Kf[/tex]
In such a way, we firstly calculate the molality of this solution according to:
[tex]m=\frac{\frac{13g}{110.262 g/mol} }{0.150kg} =0.79m[/tex]
Finally, since the Van't Hoff's factor for K2S is 3, the freezing point of the solution turns out to be:
[tex]T_F=0\°C-3*0.79m*1.86\°C/m\\\\T_F=-4.4\°C[/tex]

Sea turtles use the earths geomagnetic filed to navigate their way home. What is the reason earth has a geomagnetic filed?
Answer:
Due to the iron inside the earth.
Explanation:
Imagine a sphere of Iron, as big as two-third the size of the moon and as hot as 5700 Kelvin. That is the Earth’s core.
The iron core isn't in its liquid form even at that temperature because it is crushed under immense gravity. This core is surrounded by 2000 km of other metals like iron and nickel which are in their molten state.
The temperature is not the same at every point in this molten layer. The hotter and less dense matter rises up, and the warm denser matter sinks. This causes convectional currents in the interior of the Earth.
Because of the Earth’s spin, there is a force that is established called the Coriolis force which causes swirling whirlpools here too.
This flow of molten metals produces electric currents which generate self-sustaining magnetic fields. And as a result of the Coriolis force, all these combined effects add up to produce one big magnetic field engulfing the Earth aligned in one direction.
Bananas Foster is an example of a dessert that is flambéed. A Bananas Foster label states the accepted number of Calories to be only 300 calories, but a calorimetry experiment measured there to be 318 calories. Calculate the percent error.
Answer:
6.00%
Explanation:
Step 1: Given data
Accepted value for the number of calories in a Bananas Foster: 300 calories
Measured value for the number of calories in a Bananas Foster: 318 calories
Step 2: Calculate the percent error in the measure
We will use the following expression.
%error = |accepted value - experimental value|/ accepted value × 100%
%error = |300 cal - 318 cal|/ 300 cal × 100% = 6.00%

Answer:
I would put the final answer choice: "Scientists must first develop certain technologies before missions can be completed"
Explanation:
The first option is partially true, but we have ways around it.
The second option is straight-up false.
The third option doesn't make much sense, how can one work with technology that will be developed in the future and doesn't yet exist?

2L of hydrogen has an initial pressure of 750 mmHg, what is the final pressure in mmHg if the volume increases to 20 L with a constant temperature of 37 degrees C?
Answer: The final pressure is 75 mm Hg.
Explanation:
According to Boyle's law, at constant temperature the pressure of a gas in inversely proportional to volume.
Since, it is given that the temperature is constant. Hence, formula used is as follows.
[tex]P_{1}V_{1} = P_{2}V_{2}[/tex]
Substitute the values into above formula as follows.
[tex]P_{1}V_{1} = P_{2}V_{2}\\750 mm Hg \times 2 L = P_{2} \times 20 L\\P_{2} = \frac{750 mm Hg \times 2 L}{20 L}\\= 75 mm Hg[/tex]
Thus, we can conclude that the final pressure is 75 mm Hg.
