The distribution of electrons among orbitals in a many-electron atom is known as its electron configuration.

The electron configuration describes how electrons are distributed in the various energy levels and orbitals around the nucleus of an atom. It is represented using a series of numbers and letters that indicate the principal energy level (n), the type of orbital (s, p, d, f), and the number of electrons in each orbital.

For example, the electron configuration for carbon (C) is 1s^2 2s^2 2p^2, which shows that carbon has two electrons in the 1s orbital, two electrons in the 2s orbital, and two electrons in the 2p orbital.

The electron configuration provides important information about the arrangement and organization of electrons within an atom, which in turn affects the atom's chemical properties and reactivity.

C is the answer

a. AlCl₃ ⇒ limiting reactant(smaller ratio)

Cu ⇒ excess reactant

b. the mass of leftover reactant : 7.207 g

Given

25 g Cu

25 g AlCl3

Required

a. the excess and limiting reactants

b.  the mass of leftover reactant

Solution

Reaction

3Cu + 2AlCl₃ ⇒ 3CuCl₂ + 2Al

mol Cu(Ar = 63.5 g/mol) :

mol = mass : Mw

mol = 25 : 63.5

mol = 0.394

mol AlCl3(MW=133,34 g/mol) :

mol = 25 : 133,34 g/mol

mol = 0.187

mol ratio to reaction coefficient Cu : AlCl₃ =

\(\tt \dfrac{0.394}{3}\div \dfrac{0.187}{2}=0.131\div 0.093\)

AlCl₃ ⇒ limiting reactant(smaller ratio)

Cu ⇒ excess reactant

b. the mass of leftover reactant :

mol Cu = 3/2 x 0.187 = 0.2805

mol left = 0.394 - 0.2805 = 0.1135

mass = 0.1135 x 63.5 = 7.207 g

Answer :  The acid ionization constant (Ka) for the given acid HA is 1.1 x 10^(-5), rounded to two significant figures.

To calculate the acid ionization constant (Ka) for the given acid HA, we must first find its pH using the given concentration of the solution. Then, we can use the pH to find the concentration of H+ ions in the solution. Finally, we can plug these values into the expression for Ka to solve for the acid ionization constant.

The pH of the 0.120 M solution of HA is given to be 3.28. This means that [H+] = 10^(-pH) = 10^(-3.28) = 5.01 x 10^(-4) M.
Now, we can use the expression for Ka: Ka = [H+][A-]/[HA],  Since HA is a weak acid, we can assume that it dissociates as follows: HA + H2O ⇌ H3O+ + A- This means that [A-] = [H3O+], and [HA] = initial concentration of the acid (0.120 M) - [H3O+].

Substituting these values, we get: Ka = (5.01 x 10^(-4) M)^2 / (0.120 M - 5.01 x 10^(-4) M) = 1.1 x 10^(-5). Therefore, the acid ionization constant (Ka) for the given acid HA is 1.1 x 10^(-5), rounded to two significant figures.

Explanation:

To answer your question, we need to first understand what mole fraction is. Mole fraction is the ratio of the number of moles of one component in a mixture to the total number of moles in the mixture. The mole fraction of acetone in the resulting mixture is 0.236.

In this case, we are dealing with a binary mixture of water and acetone, with equal masses of both substances.
To find the mole fraction of acetone in the mixture, we first need to determine the number of moles of each substance. We can do this by using the formula:
Number of moles = Mass / Molar mass
The molar mass of water is 18 g/mol, and the molar mass of acetone is 58 g/mol. If we assume that we have 100 grams of each substance, we can calculate the number of moles of each as follows:
Number of moles of water = 100 g / 18 g/mol = 5.56 moles
Number of moles of acetone = 100 g / 58 g/mol = 1.72 moles
The total number of moles in the mixture is simply the sum of these two values:
Total number of moles = 5.56 moles + 1.72 moles = 7.28 moles
To find the mole fraction of acetone, we divide the number of moles of acetone by the total number of moles:
Mole fraction of acetone = Number of moles of acetone / Total number of moles = 1.72 moles / 7.28 moles = 0.236
Therefore, the mole fraction of acetone in the resulting mixture is 0.236.

The hydrogen atom before the ionization happened was in its ground state. The energy required to remove an electron from a hydrogen atom is known as ionization energy.

In this case, the ionization energy was measured to be 0.850 electron volts (eV). When an electron is in the ground state of the hydrogen atom, it has the lowest energy possible.

The ground state electron is located in the lowest energy level or orbital, which is the 1s orbital. If an electron in the ground state absorbs energy equal to or greater than the ionization energy, it will become ionized and leave the atom.

Therefore, the hydrogen atom must have been in its ground state before the ionization occurred since ionization energy is the energy required to remove an electron from the ground state of an atom.

Among the given options, SO2, SO3, and SO32- can exhibit delocalized bonding.

Delocalized bonding is a type of bonding where the electrons are not localized between two atoms but rather are shared among multiple atoms in a molecule. This type of bonding is characterized by the presence of resonance structures and is commonly observed in molecules that contain pi bonds.

SO2 has a bent structure with a lone pair of electrons on the sulfur atom. The double bond between sulfur and oxygen involves the overlap of a p orbital on sulfur and a p orbital on one of the oxygen atoms. This results in a pi bond and a sigma bond. The pi electrons are delocalized between the sulfur and oxygen atoms, and resonance structures can be drawn to show the delocalization.

SO3 has a trigonal planar structure with all three sulfur-oxygen bonds being identical. The sulfur atom in SO3 uses its three 3p orbitals to form three sigma bonds with the three oxygen atoms. The remaining 3p orbital on sulfur overlaps with the p orbitals on the three oxygen atoms to form three pi bonds. The pi electrons are delocalized over all three sulfur-oxygen bonds.

SO32- has a resonance structure in which the negative charge is delocalized over the sulfur and two oxygen atoms. The two sulfur-oxygen double bonds can be described as a combination of one strong sigma bond and one weaker pi bond, resulting in the delocalization of electrons over the sulfur-oxygen bonds.

In summary, SO2, SO3, and SO32- can exhibit delocalized bonding due to the presence of pi bonds and the ability to form resonance structures.

Answer:

Salt is any neutral chemical compound made of cations (positive ions) attached to anions (negative ions). The main kind of salt is sodium chloride with the chemical formula NaCl. It is formed when hydrochloric acid is added in sodium hydroxide.

To achieve the final pH, you need to add 13.3 mL of a 6.0 M HCl solution to the 800.0 mL of a 0.10 M NaAc solution.


1. Calculate the moles of NaAc in the solution
2. Use the Henderson-Hasselbalch equation to find the moles of HCl needed
3. Calculate the volume of the 6.0 M HCl solution needed


1. Moles of NaAc: M = n/V => n = M * V => n = 0.10 mol/L * 0.800 L = 0.080 mol
2. Henderson-Hasselbalch equation: pH = pKa + log([A-]/[HA]).

Sodium acetate (NaAc) is the conjugate base of acetic acid, and the pKa of acetic acid is 4.76. We need to find the ratio of [A-]/[HA] that gives the desired pH, assuming the final pH equals the pKa (4.76) because it is the optimal buffering capacity: 4.76 = 4.76 + log([A-]/[HA]) => log([A-]/[HA]) = 0 => [A-]/[HA] = 1. This means that we need an equal amount of moles of HCl (which will convert NaAc to its conjugate acid, HA) to achieve the desired pH: 0.080 mol HCl.
3. Volume of 6.0 M HCl solution: M = n/V => V = n/M => V = 0.080 mol / 6.0 mol/L = 0.0133 L or 13.3 mL

The volume of hydrogen gas produced in the reaction is approximately 0.67 m³. None of the given option is correct.

To determine the volume of hydrogen gas produced in the reaction, we need to calculate the number of moles of hydrogen gas first. Then, we can use the ideal gas law to convert the number of moles to volume at room temperature and pressure.

From the balanced chemical equation:

Zn + 2HCl -> ZnCl₂ + H₂

We can see that 1 mole of zinc reacts with 2 moles of hydrochloric acid to produce 1 mole of hydrogen gas.

Given:

Mass of zinc (Zn) = 4.55 g

Molar mass of zinc (Zn) = 65.38 g/mol

Concentration of hydrochloric acid (HCl) = 2.25 mol/dm³

Volume of hydrochloric acid (HCl) = 50 cm³ = 50 × 10⁻³ dm³

First, we calculate the number of moles of zinc:

Number of moles of zinc (Zn) = Mass / Molar mass = 4.55 g / 65.38 g/mol

Since the ratio between zinc and hydrogen gas is 1:1, the number of moles of hydrogen gas produced is also equal to the number of moles of zinc.

Now, we can convert the number of moles of hydrogen gas to volume using the ideal gas law:

PV = nRT

Assuming room temperature (around 298 K) and pressure (around 1 atm), we can rearrange the equation to solve for volume (V):

V = nRT / P

Plugging in the values:

V = (Number of moles of hydrogen gas) × (Ideal gas constant) × (Temperature) / (Pressure)

Calculating the volume of hydrogen gas:

V = (4.55 g / 65.38 g/mol) × (0.0821 dm³·atm/mol·K) × (298 K) / (1 atm)

V ≈ 0.67 dm³

Converting to the desired units:

V ≈ 0.67 × 10³ cm³ = 0.67 × 10³ × 10⁻³ m³ = 0.67 m³

None of the given answer options match the calculated volume, so it seems there might be an error in the provided options.

To determine the enthalpy change (ΔH) for the reaction, we can use the given standard molar enthalpies of formation (∆Hf) for the reactants and products involved.

The equation for the reaction is:

∆Hf(CH3OCH3) = ∆Hf(C2H5OH) - ∆Hf(H2O) - ∆Hf(CO2)

Substituting the given values:

∆Hf(CH3OCH3) = -1460.4 kJ/mol - (-276 kJ/mol -285.83 kJ/mol -393.52 kJ/mol)

Simplifying:

∆Hf(CH3OCH3) = -1460.4 kJ/mol + 955.35 kJ/mol

∆Hf(CH3OCH3) = -505.05 kJ/mol
