At a pressure of 1. 00 atm and a temperature of 20°C, 1. 72 g CO2 win dissolve in 1L of water. How much CO2 will dis solve if the pressure is raised to 1. 35 atm and the temperature stays the same?

Answers

Answer 1

2.32 g of  CO2 will dissolve if the pressure is raised to 1. 35 atm and the temperature will remain the same.

The given data is:

Pressure = 1 atm

Temperature = 20 degrees =  293 K

CO2 weight = 1.72g

Water weight = 1L

Henry's law is used which defines that the amount of gas dissolved in a fluid is proportional to the partial pressure of the gas beyond the liquid.

Mathematically,

C = kH * P

C is the concentration of the gas given.

1.72 g CO2 / 44.01 g/mol = 0.039 mol CO2

C = 0.039 mol/L

kH = C/P

kH = 0.039 mol/L / 1 atm = 0.039 mol/(L*atm)

CO2 when the pressure is raised to 1.35 atm:

P' = 1.35 atm

C' = kH * P'

C' = (0.039 mol/(L*atm)) * 1.35 atm

C' = 0.0527 mol/L

The amount of CO2 dissolved in the water is

m = C' * M * V

m = 0.0527 mol/L * 44.01 g/mol * 1 L

m = 2.32 g

Therefore, a pressure of 1.35 atm is required and at a temperature of 20°C,  makes 2.32g of CO2 will dissolve.

in which case the reaction in the gas mixture will proceed nonspontaneously in the forward direction?

Answers

The reaction in the gas mixture will proceed non-spontaneously in the forward direction when the standard free energy change (∆G°) is positive or zero.

What is spontaneous reaction?

In chemical reactions, the term spontaneity refers to whether the reaction proceeds on its own or requires an input of energy to occur. When ∆G° is negative, a reaction is said to be spontaneous in the forward direction, meaning it occurs naturally without any external input of energy. When ∆G° is positive or zero, on the other hand, the reaction proceeds nonspontaneously in the forward direction.

In other words, the reaction requires energy input to proceed. The free energy change (∆G) of a reaction is related to its standard free energy change (∆G°) through the equation:

∆G = ∆G° + RT ln(Q)

where, R is the gas constant, T is the temperature in Kelvin, and Q is the reaction quotient.

If Q = 1, the reaction is at equilibrium and ∆G = ∆G°. If Q < 1, the reaction proceeds spontaneously in the forward direction (∆G < 0), and if Q > 1, the reaction proceeds spontaneously in the reverse direction (∆G > 0).

Plutonium-238 is a radioactive element used as a power source in spacecraft like Voyager and New Horizons. It has a half life of 87.7 years. Suppose we have 2 kg of plutonium-238 right now. How much plutonium will be left in 87.7 years? A) None B) 0.25 kg C) 0.5 kg D) 1.0 kg E) 2 kg

Answers

The answer is C) 0.5 kg. This is because Plutonium-238 has a half-life of 87.7 years, which means that after 87.7 years, half of the original amount of Plutonium-238 will remain. In this case, that would be 2 kg * 0.5 = 0.5 kg.

Plutonium-238 is a radioactive element used as a power source in spacecraft like Voyager and New Horizons. It has a half-life of 87.7 years. Suppose we have 2 kg of plutonium-238 right now. Radioactive decay is a random event. So, it is impossible to predict when a specific atom will decay. But we can find how much radioactive material is remaining after a specific period of time.

The half-life of a radioactive material is the time required for half of the radioactive material to decay. The formula to calculate the remaining material is:

N(t) = N0 × (1/2)^(t/t1/2)

Where N(t) is the remaining material at time t, N0 is the initial material, t1/2 is the half-life, and t is the elapsed time.

The initial material is 2 kg, half-life is 87.7 years, and the elapsed time is also 87.7 years.

N(87.7) = 2 kg × (1/2)^(87.7/87.7)= 1 kg × 0.5= 0.5 kg

Therefore, the amount of plutonium remaining after 87.7 years will be 0.5 kg. So, the answer is option C.

To determine if a data point can be ignored when calculating the average in General Chemistry, Appendix D of the lab manual recommends using the Q-test at 95% confidence. The Q-test is a statistical test that is used to determine if a data point is an outlier, or if it falls outside the expected range of values for the data set.

To use the Q-test, one must calculate the Q-value for each data point and compare it to the critical Q-value at the desired level of confidence. If the calculated Q-value is greater than the critical Q-value, then the data point is considered an outlier and can be excluded from the calculation of the average.

Regarding the second question, the spectator ions in the reaction between aqueous perchloric acid and aqueous barium hydroxide are H+ and ClO4-.

These three options are correct for assisting crystal formation- 1. Scrape the inside of the Erlenmeyer flask with a glass rod below the surface of the solvent. 2. Nucleate the crystals with a scrap of paper. 3. Include some crystals of the compound being crystallized.

What is crystallization?

Crystallization is the process by which a solid material forms a structured arrangement of its particles, producing a highly ordered and frequently repeating pattern. The formation of solid crystals such as salt, sugar, and diamonds exemplifies this. When the molecules of a solid tend to organize themselves into a more ordered pattern, this is referred to as crystallization.

How adding a scrap of paper to nucleate the crystals will result in formation of crystals?

Seeding is the process of adding a scrap of paper to nucleate the crystals. Seeding entails placing a small crystal in a container of supersaturated solution, which serves as a nucleus for other crystals to form around. This process accelerates crystal growth and can be used to produce larger, more consistent crystals. It can also be used to make crystals of various shapes and sizes. The addition of a scrap of paper causes the solution to form around it, promoting crystal formation.

Answers

The atomic number of an atom is determined by counting the number of protons in the nucleus. This is because the atomic number is defined as the number of protons in an atom's nucleus.

What is atomic number?

The atomic number is the number of protons in an atom. The periodic table is arranged according to atomic number, which determines the chemical properties of an element. All neutral atoms of a given element have the same number of protons and electrons.

A neutral atom has an equal number of positively charged protons and negatively charged electrons, which results in no overall charge.The electron arrangement in an atom determines how it will interact with other atoms. The element's chemical properties are determined by the electron configuration of its atoms.

The number of protons in the nucleus determines the element's atomic number, which is a fundamental property of the element. The atomic number identifies the element and its position on the periodic table.

Then a statement somewhat in detail of a course to be pursued seemed fitting and proper. Now, at the expiration of four years, during which public declarations have been constantly called forth on every point and phase of the great contest which still absorbs the attention and engrosses the energies of the nation, little that is new could be presented. The progress of our arms, upon which all else chiefly depends, is as well known to the public as to myself, and it is, I trust, reasonably satisfactory and encouraging to all. With high hope for the future, no prediction in regard to it is ventured.On the occasion corresponding to this four years ago all thoughts were anxiously directed to an impending civil war. All dreaded it, all sought to avert it. While the inaugural address was being delivered from this place, devoted altogether to saving the Union without war, insurgent agents were in the city seeking to destroy it without war seeking to dissolve the Union and divide effects by negotiation. Both parties deprecated war, but one of them would make war rather than let the nation survive, and the other would accept war rather than let it perish, and the war came.One-eighth of the whole population were colored slaves, not distributed generally over the Union, but localized in the southern part of it. These slaves constituted a peculiar and powerful interest. All knew that this interest was somehow the cause of the war. To strengthen, perpetuate, and extend this interest was the object for which the insurgents would rend the Union even by war, while the Government claimed no right to do more than to restrict the territorial enlargement of it. Neither party expected for the war the magnitude or the duration which it has already attained. Neither anticipated that the cause of the conflict might cease with or even before the conflict itself should cease. Each looked for an easier triumph, and a result less fundamental and astounding. Both read the same Bible and pray to the same God, and each invokes His aid against the other. It may seem strange that any men should dare to ask a just God's assistance in wringing their bread from the sweat of other men's faces, but let us judge not, that we be not judged. The prayers of both could not be answered. That of neither has been answered fully. The Almighty has His own purposes."Woe unto the world because of offenses; for it must needs be that offenses come, but woe to that man by whom the offense cometh." If we shall suppose that American slavery is one of those offenses which, in the providence of God, must needs come, but which, having continued through His appointed time, He now wills to remove, and that He gives to both North and South this terrible war as the woe due to those by whom the offense came, shall we discern therein any departure from those divine attributes which the believers in a living God always ascribe to Him? Fondly do we hope, fervently do we pray, that this mighty scourge of war may speedily pass away. Yet, if God wills that it continue until all the wealth piled by the bondsman's two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said "the judgments of the Lord are true and righteous altogether."With malice toward none, with charity for all, with firmness in the right as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation's wounds, to care for him who shall have borne the battle and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves and with all nations.
