A liquid is placed in an evacuated, sealed flask. When will this closed system reach dynamic equilibrium?

Answers

Answer 1

Answer:

The liquid that is placed in an evacuated sealed flask will reach in dynamic equilibrium if the amount of liquid inside the flask will stop converting into vapor. This process is to balanced the amount of substance of both phases inside the flask.

in a second experiment, the total pressure is observed to be 58 atm. what is the partial pressure of the water vapor produced?

Answers

The partial pressure exerted by a gas in a mixture, depends on the mole

fraction of the gas and the pressure exerted by the mixture.

The partial pressure of H₂O is 20 atm.

Reasons:

Given parameters are;

Explosion equation is 4C₃H₅N₃O₉ → 12CO₂(g) + O₂(g) + 6N₂(g) + 10H₂O(g)

Amount of nitroglycerine = 227 g

Molar mass of nitroglycerine = 227 g/mol

Required:

Partial pressure of the water vapor

Solution:

Number of moles of nitroglycerine in the reaction = 1 mole

Therefore;

Number of moles of CO₂ = 12/4 = 3 moles

Number of moles of O₂ = 0.25 moles

Number of nitrogen, N = 1.5 moles

Number of moles of H₂O = 2.5 moles

$Mole \ fraction \ of \ H_2O, \ X_(H_2O) = (2.5)/(2.5 + 1.5 + 0.25 + 3) = (10)/(29)$

According to Raoults law, we have;

The partial pressure of H₂O = $X_(H_2O) * P_$

Therefore, partial pressure of H₂O = $(10)/(29) * 58$ = 20 atm.

This is an incomplete question, here is a complete question.

Nitroglycerine (C₃H₅N₃O₉) explodes with tremendous force due to the numerous gaseous products. The equation for the explosion of Nitroglycerine is:

$4C_3H_5N_3O_9(l)\rightarrow 12CO_2(g)+O_2(g)+6N_2(g)+10H_2O(g)$

A scientist conducts an experiment to characterize a bomb containing nitroglycerine. She uses a steel, ridge container for the test.

Volume of rigid steel container: 1.00 L

Molar mass of Nitroglycerine: 227 g/mol

Temperature: 300 K

Amount of Nitroglycerine tested: 227 g

Value for ideal gas constant, R: 0.0821 L.atm/mol.K

In a second experiment, the total pressure is observed to be 58 atm. what is the partial pressure of the water vapor produced?

Answer : The partial pressure of the water vapor is, 20.01 atm

Explanation :

First we have to calculate the moles of $C_3H_5N_3O_9$

$\text{Moles of }C_3H_5N_3O_9=\frac{\text{Given mass }C_3H_5N_3O_9}{\text{Molar mass }C_3H_5N_3O_9}=(227g)/(227g/mol)=1mol$

Now we have to calculate the moles of $CO_2,O_2,N_2\text{ and }H_2O$

The balanced chemical reaction is:

$4C_3H_5N_3O_9(l)\rightarrow 12CO_2(g)+O_2(g)+6N_2(g)+10H_2O(g)$

From the balanced chemical reaction we conclude that,

As, 4 moles of $C_3H_5N_3O_9$ react to give 12 moles of $CO_2$

So, 1 moles of $C_3H_5N_3O_9$ react to give $(12)/(4)=3$ moles of $CO_2$

and,

As, 4 moles of $C_3H_5N_3O_9$ react to give 1 moles of $O_2$

So, 1 moles of $C_3H_5N_3O_9$ react to give $(1)/(4)=0.25$ moles of $O_2$

and,

As, 4 moles of $C_3H_5N_3O_9$ react to give 6 moles of $N_2$

So, 1 moles of $C_3H_5N_3O_9$ react to give $(6)/(4)=1.5$ moles of $N_2$

and,

As, 4 moles of $C_3H_5N_3O_9$ react to give 10 moles of $H_2O$

So, 1 moles of $C_3H_5N_3O_9$ react to give $(10)/(4)=2.5$ moles of $H_2O$

Now we have to calculate the mole fraction of water.

$\text{Mole fraction of }H_2O=\frac{\text{Moles of }H_2O}{\text{Moles of }H_2O+\text{Moles of }CO_2+\text{Moles of }O_2+\text{Moles of }N_2}$

$\text{Mole fraction of }H_2O=(2.5)/(2.5+3+0.25+1.5)=0.345$

Now we have to calculate the partial pressure of the water vapor.

According to the Raoult's law,

$p_(H_2O)=X_(H_2O)* p_T$

where,

$p_(H_2O)$ = partial pressure of water vapor gas = ?

$p_T$ = total pressure of gas = 58 atm

$X_(H_2O)$ = mole fraction of water vapor gas = 0.345

Now put all the given values in the above formula, we get:

$p_(H_2O)=X_(H_2O)* p_T$

$p_(H_2O)=0.345* 58atm=20.01atm$

Therefore, the partial pressure of the water vapor is, 20.01 atm

A group of students were discussing the lonization energies of Selenium and Flourine. Which student is correct for the reason why their element has the highest lonization energy? O A Student C says F because the larger the atom, the stronger the attraction between protons and valence electrons. The stronger the attraction the more energy is needed to remove a valence electron. B. Student B says Se because the smaller the atom, the stronger the attraction between protons and valence electrons. The stronger the attraction, the more energy is needed to remove a valence electron. C. Student D says F because the smaller the atom, the stronger the attraction between protons and valence electrons. The stronger the attraction, the more energy is needed to remove a valence electron. OD. Student A says Se because the larger the atom, the stronger the attraction between protons and valence electrons. The stronger the attraction the more energy is needed to remove a valence electron.

Answers

The correct student is Student D, who says that Fluorine (F) has the highest ionization energy because the smaller the atom, the stronger the attraction between protons and valence electrons.

The stronger the attraction, the more energy is needed to remove a valence electron.

Ionization energy refers to the energy required to remove an electron from an atom. Smaller atoms have a stronger attraction between the positively charged protons in the nucleus and the negatively charged electrons in the outermost energy level. As a result, it takes more energy to remove an electron from a smaller atom like fluorine. This is because the electrons are held more tightly due to the stronger attraction.

So, the reasoning provided by Student D correctly explains why Fluorine has the highest ionization energy among Selenium (Se) and Fluorine (F).

I think the Answer is C because Flourine is stronger in electron attraction and is smaller so it has a stronger electronic pull. Hope this helps :)

Which of the following best describes what happens when molecular compounds melt? A.) Molecules separate into their component atoms. B.)Molecules move more slowly. C.) Molecules arranged in an irregular pattern change to a regular pattern. D.) Molecules arranged in a regular pattern change to an irregular patter.

I think the correct answer from the choices listed above is option D. When a molecular compound melts, they undergo the process of phase change from solid to liquid therefore molecules arranged in a regular pattern change to an irregular pattern. Hope this answers the question.

Name four non-metal that could take the electron that the lithium loses when forming bonds

Answers

The elements that accept the electron of Lithium are Fluorine, Chlorine, Bromine, and Iodine.

Metals and nonmetals are the elements in the periodic table that gains and lose electrons to form chemical bonds.

The metals are a compound that loses electrons and nonmetals gains electrons to form a chemical bond.

Elements bonding with Lithium

Lithium has been a group 1 element with 1 valence electron. It has been bonding with the nonmetals that accept the electrons and form the bond. The elements complete their octet and become stable.

The nonmetals that require an electron to complete their octet are halogens. Thus, the elements that accept the electron of Lithium are Fluorine, Chlorine, Bromine, and Iodine.
