Explanation:

This is an extension of Graham's Law of Effusion where [tex]\frac{R1}{R2} = \sqrt{\frac{M2}{M1} } = \frac{t2}{t1}[/tex]

We're only talking about molar mass and time (t) here so we'll just concentrate on [tex]\sqrt{\frac{M2}{M1} } = \frac{t2}{t1}[/tex]. Notice how the molar mass and time are on the same position, recall effusion is when gas escapes from a container through a small hole. The time it takes it to leave depends on the molar mass. If the gas is heavy, like Xe, it would take a longer time (4.83 minutes). If it was light it would leave in less time, that gives us somewhat an idea what our element could be, we know that it's atleast an element before Xenon.

Let's plug everything in and solve for M2. I chose M2 to be the unknown here because it's easier to have it basically as a whole number already.

[tex]\sqrt{\frac{M2}{131} } = \frac{2.29}{4.83}[/tex]

The square root is easier to deal with if you take it out in the first step, so let's remove it by squaring each side by 2, the opposite of square root essentially.

[tex](\sqrt{\frac{M2}{131} } )^2= (\frac{2.29}{4.83})^2[/tex]

[tex]{\frac{M2}{131} } = (0.47)^2[/tex]

[tex]{\frac{M2}{131} } = 0.22[/tex]

M2= 0.22 x 131

Answer:

The concentration of this NaCl solution is 0.0769M

Explanation:

Hello there!

In this case, since we are dealing with a solubility equilibrium in which it is desired to compute the concentration of a common-ion effect to chloride solution in the form of NaCl, we can set up the equilibrium reaction and expression:

[tex]AgCl(s)\rightleftharpoons Ag^+(aq)+Cl^-(aq)\\\\Ksp=[Ag^+][Cl^-]\\[/tex]

It is possible to insert the concentration of starting chloride ions provided by the ionization of NaCl and in terms of the molar solubility, s, equal to 2.38x10^{-9}M:

[tex]Ksp=(s)(C+s)\\\\1.83x10^{-10}=(2.38x10^{-9})(M+2.38x10^{-9})[/tex]

Thus, solving for M, we obtain:

[tex]\frac{1.83x10^{-10}}{2.38x10^{-9}} =M+2.38x10^{-9}\\\\M=\frac{1.83x10^{-10}}{2.38x10^{-9}} -2.38x10^{-9}\\\\M=0.0769M[/tex]

Thus, the concentration of this NaCl solution is 0.0769M.

Explanation:

The number of carbon atoms present in 1.25 mol of silver acetate is 1.875 × 10²³.

Avogadro's number is define as the number of atoms of any substance present in one mole of that substance, and it is equal to 6.022 × 10²³, i.e.
1 mole = 6.022 × 10²³ atoms/mol

Given moles of silver acetate = 1.25 moles

Number of atoms of silver acetate in 1.25 moles = 1.25 × 6.022 × 10²³ = 7.5×10²³

Molecular formula of silver acetate is CH₃CO₂Ag, means in this molecule total 8 atoms are present so number of carbon atom will be calculated as:

Carbon atoms = (2× 7.5 × 10²³) / 8 = 1.875 × 10²³ atoms [here we multiply by 2 because 2 atoms of carbon is present in olecule]

Hence required atoms of carbon is 1.875 × 10²³.

Answer:

It is double displacement reaction

The new volume of the neon gas as its temperature is reduced is 2.29L.

Charles's law states that "the volume occupied by a definite quantity of gas is directly proportional to its absolute temperature.

It is expressed as;

V₁/T₁ = V₂/T₂

Given the data in the question;

To determine the new volume of the neon gas, we substitute our given values into the expression above.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂ / T₁

V₂ = ( 2.5L × 298.15K ) / 325.15K

V₂ = 745.375LK / 325.15K

V₂ = 2.29L

Therefore, the new volume of the neon gas as itstemperature is reduced is 2.29L.

Answer:

D 8.8

Explanation:

To solve this question you must know that, using the kw equation:

Kw = 1x10⁻¹⁴ = [H⁺] [OH⁻]

-log 1x10⁻¹⁴ = -log ([H⁺] [OH⁻])

14= -log [H⁺] + -log [OH⁻]

As pH = -log[H⁺] and pOH = -log [OH⁻]

we can obtain the equation:

pH = 14 - pOH

As the pOH of the solution is 5.2:

pH = 14 - 5.2

There are two types of nuclear reactions. Nuclear fission and nuclear fusion.

Nuclear reactions are classified into two types: fission and fusion. Nuclear fusion is the collision of two or more light nuclei to produce a heavier nucleus. Nuclear fusion happens in low-atomic-number elements such as hydrogen. Nuclear fusion is the inverse of nuclear fission, in which heavy atoms scatter and lighter elements are produced. Nuclear fusion and fission both provide massive quantities of energy.

A nuclear process in which low-atomic-number atomic nuclei fuse to form a heavier nucleus, releasing energy.

Every star in the universe, including the sun, is alive because of nuclear fusion. As a result of this activity, they create enormous amounts of heat.

Fission is a nuclear phenomenon in which a heavy nucleus spontaneously fractures or collides with another particle, releasing energy. Nuclear fission happens when an atom's nucleus splits into lighter nuclei as a result of a nuclear process. This decay can occur naturally due to radioactive decay, or it can be mimicked in a laboratory by creating the necessary conditions (bombarding with neutrinos). The overall mass of the resulting fragments is less than that of the original. The missing mass is converted into nuclear energy in the preceding step.

Hence option D is correct.

Answer:

The pressure of the gas at 23 C is 179.92 kPa.

Explanation:

Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.

In short, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.

Gay-Lussac's law can be expressed mathematically as follows:

[tex]\frac{P}{T} =k[/tex]

Studying two states, one initial 1 and the other final 2, it is satisfied:

[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{310 kPa}{510 K} =\frac{P2}{296 K}[/tex]

Solving:

[tex]P2=296 K*\frac{310 kPa}{510 K}[/tex]

P2= 179.92 kPa

The pressure of the gas at 23 C is 179.92 kPa.

The particles in the nucleus are changed, and one element is transformed into another element when particles in the nucleus are gained or lost.

Nuclear reactions are processes in which one or more nuclides are produced from the collisions between two atomic nuclei or one atomic nucleus and a subatomic particle.

This was the first observation of an induced nuclear reaction, that is, a reaction in which particles from one decay are used to transform another atomic nucleus.

The most notable man-controlled nuclear reaction is the fission reaction which occurs in nuclear reactors. A target nucleus are within the range of nuclear forces for the time allowing for a large number of interactions between nucleons.

  CH₂OH

Fischer projection is a two-dimensional representation of a three-dimensional molecule. In Fischer projection, the carbon atoms are drawn as vertical lines, and the hydrogen atoms and hydroxyl groups are drawn on the right-hand side or left-hand side of the carbon atoms. The carbonyl group is always drawn at the top of the Fischer projection.

The L-configuration is a type of configuration that is assigned to organic molecules based on the orientation of the hydroxyl group on the penultimate carbon atom. If the hydroxyl group is on the left-hand side of the Fischer projection, the molecule is assigned the L-configuration. If the hydroxyl group is on the right-hand side of the Fischer projection, the molecule is assigned the D-configuration.

In the Fischer projection of L-ketononose, the hydroxyl group on the penultimate carbon atom is on the left-hand side, so the molecule is assigned the L-configuration.

Answer:

THE MOLARITY IS 2.22 MOL/DM3

Explanation:

The solution formed was as a result of dissolving 37.5 g of Na2S in 217 g of water

Relative molecular mass of Na2S = ( 23* 2 + 32) = 78 g/mol

Molarity in g/dm3 is the amount of the substance dissolved in 1000 g or 1 L of the solvent. So we have;

37.5 g of Na2S = 217 g of water

( 37.5 * 1000 / 217 ) g = 1000 g of water

So, 172.81 g/dm3 of the solution

So therefore, molarity in mol/dm3 = mol in g/dm3 / molar mass

Molarity = 172.81 g/dm3 / 78 g/mol

Molarity = 2.22 mol/dm3

The molarity of the solution is 2.22 mol/dm3
