The elements that have an outer electron configuration of ms2nd2 are located in the d-block of the periodic table and include some of the transition metals and lanthanides.

To determine which elements in the periodic table have this outer electron configuration, you can look at the position of the d-block elements in the table. The d-block elements are located in the middle of the table and include the transition metals. These elements have partially filled d orbitals, which can accommodate up to 10 electrons.

Elements in the d-block with an atomic number of 21 through 30 (scandium through zinc) have an outer electron configuration of d10s2 and do not fit the ms2nd2 configuration. However, elements in the d-block with an atomic number of 39 through 48 (yttrium through cadmium) have an outer electron configuration of d10s2p1 and can have the ms2nd2 configuration by removing the single electron in the p orbital. Elements in the d-block with an atomic number of 57 through 80 (lanthanum through mercury) also have the possibility of having an outer electron configuration of ms2nd2.

The density of sulfur dioxide gas at a temperature of 15°C and pressure of 300 torr is 0.001022 g/cm³, or 0.001022 g/mL, or 1.022 kg/m³, or 0.01022 g/L when converted to atm.

What is density?

To calculate the density of sulfur dioxide gas at a temperature of 15°C and a pressure of 300 torr, we can use the ideal gas law:

PV = nRT

where P is the pressure in atmospheres, V is the volume in liters, n is the number of moles, R is the ideal gas constant (0.08206 L·atm/(mol·K)), and T is the temperature in Kelvin.

First, we need to convert the given temperature of 15°C to Kelvin:

T = 15°C + 273.15 = 288.15 K

Next, we can rearrange the ideal gas law to solve for the number of moles:

n = PV/RT

where we can use the given pressure of 300 torr and convert it to atm by dividing by 760 torr/atm:

P = 300 torr / 760 torr/atm = 0.3947 atm

Substituting the values into the equation, we get:

n = (0.3947 atm) V / (0.08206 L·atm/(mol·K) × 288.15 K)

Now, we can use the molar mass of sulfur dioxide, which is 64.06 g/mol, to convert the number of moles to mass:

mass = n × molar mass

Finally, we can calculate the density of sulfur dioxide gas using the mass and volume:

density = mass / V

To convert the density from g/L to g/cm³, we divide by 1000.

Putting it all together, we get:

n = (0.3947 atm) V / (0.08206 L·atm/(mol·K) × 288.15 K)

n = 0.01595 V

mass = n × molar mass = 0.01595 V * 64.06 g/mol = 1.022 gV

density = mass / V = 1.022 gV / V = 1.022 g/L = 0.001022 g/cm³

Therefore, the density of sulfur dioxide gas at a temperature of 15°C and pressure of 300 torr is 0.001022 g/cm³, or 0.001022 g/mL, or 1.022 kg/m³, or 0.01022 g/L when converted to atm.

The Ammonium Chloride solution at 0.25 M has a pH of 2.67.

As a result, the weak basic (Chlorine) in the solution is overpowered by the conjugate acid (Ammonium cation), making the solution mildly acidic. According to the equation pH =log[Hydrogen ion], an acidic solution has a pH lower than 7. Aqueous ammonium chloride solution has a pH that is less than 7.

Ammonium cation + Water ⇌ Nitrogen trihydride + Hydronium ion

Kb = [Nitrogen trihydride][Hydronium ion] / [Ammonium cation]

[Nitrogen trihydride] = [Hydronium ion] = x

[Ammonium cation] = 0.25 - x

Kb = [Nitrogen trihydride][Hydronium ion] / [Ammonium cation]

1.8 × 10–5 = x² / (0.25 - x)

1.8 × 10–5 = x² / 0.25

x² = 4.5 × 10–6

x = 2.12 × 10–3

The final temperature is -160°C

We can use the combined gas law, which relates the pressure, volume, and temperature of a gas:

(P₁V₁)/T₁ = (P₂V₂)/T₂

Where

In this case, we can assume that the pressure of the gas is constant, since it is not given in the problem statement. So we can simplify the equation to:

(V₁/T₁) = (V₂/T₂)

Where

We are given that the initial volume (V₁) is 80 L and the final volume (V₂) is twice that, or 160 L. We are also given that the initial temperature (T₁) is -40°C. To find the final temperature (T₂), we can plug these values into the equation:

(V₁/T₁) = (V₂/T₂)

(80 L)/(-40°C) = (160 L)/T₂

Simplifying:

-2 L/°C = (160 L)/T₂

Multiplying both sides by -1°C/2 L (the reciprocal of -2 L/°C):

1/2 = (T₂)/(160 L) x (-1°C/2 L)

1/2 = -T₂/320

Multiplying both sides by -1 to isolate T₂:

-1/2 = T₂/320

T₂ = -160°C

Therefore, the final temperature is -160°C.

Here's a more detailed step-by-step calculation for the theoretical yield and percent yield of chromium (Cr) in the given reaction:

Given: Mass of chromium(III) oxide (Cr2O3) = 80.0 g Mass of carbon (C) = 8.00 g Actual yield of Cr = 21.7 g

Step 1: Calculate the molar mass of Cr2O3 and C. Molar mass of Cr2O3 = 2 x (51.996 g/mol) + 3 x (15.999 g/mol) = 151.996 g/mol Molar mass of C = 12.011 g/mol

Step 2: Convert the masses of Cr2O3 and C to moles. Moles of Cr2O3 = Mass of Cr2O3 / Molar mass of Cr2O3 = 80.0 g / 151.996 g/mol = 0.527 mol (rounded to three decimal places)

Moles of C = Mass of C / Molar mass of C = 8.00 g / 12.011 g/mol = 0.666 mol (rounded to three decimal places)

Step 3: Determine the limiting reactant. The limiting reactant is the one that is completely consumed and determines the maximum amount of product that can be formed. In this case, we compare the moles of Cr2O3 and C to see which one is limiting.

From the balanced equation: Cr2O3 + 3C -> 2Cr + 3CO

We can see that 1 mol of Cr2O3 requires 3 moles of C to react completely and produce 2 moles of Cr. Therefore, the limiting reactant is C, as we have 0.666 mol of C, which is less than the 0.527 mol of Cr2O3.

Step 4: Calculate the theoretical yield of Cr. The theoretical yield of Cr is the maximum amount of Cr that can be obtained based on the limiting reactant.

Moles of limiting reactant (C) = 0.666 mol Molar mass of Cr = 51.996 g/mol

Theoretical yield of Cr = Moles of limiting reactant (C) x Molar mass of Cr = 0.666 mol x 51.996 g/mol = 34.65 g (rounded to two decimal places)

Step 5: Calculate the percent yield of Cr. The percent yield is a measure of how much of the theoretical yield was actually obtained.

Actual yield of Cr = 21.7 g Theoretical yield of Cr = 34.65 g

Percent yield = (Actual yield / Theoretical yield) x 100% = (21.7 g / 34.65 g) x 100% = 62.7% (rounded to three significant figures)

Therefore, the percent yield for the reaction is approximately 62.7%.

NaOH (sodium hydroxide) is considered a strong base. A strong base is a base that dissociates completely in water to form hydroxide ions (OH-) and cations. NaOH is highly soluble in water and, when added to water, it completely dissociates into Na+ and OH- ions, which makes it a strong base.

The strength of a base depends on the extent of its dissociation in water. Strong bases dissociate completely in water, while weak bases dissociate only partially. The dissociation of a base is usually represented by its base dissociation constant (Kb), which is the equilibrium constant for the reaction of the base with water to form hydroxide ions.

a. The conjugate base of aspirin (acetylsalicylic acid) is formed when the acidic proton (H+) is removed from the carboxylic acid group (-COOH) in the molecule.

b. The percentage of aspirin available for absorption depends on the degree of ionization of the molecule, which is related to the pH of the surrounding medium. At pH values below the pKa (2.97), most of the molecules exist in the protonated form (HA), while at pH values above the pKa, most of the molecules exist in the deprotonated form (A-).

Using the Henderson-Hasselbalch equation:

pH = pKa + log([A-]/[HA])

We can calculate the ratio of deprotonated (A-) to protonated (HA) forms at different pH values. At pH 2.0, the ratio is:

2.0 = 2.97 + log([A-]/[HA])

log([A-]/[HA]) = -0.97

[A-]/[HA] = 0.12

So, at pH 2.0, only 12% of the aspirin molecules are in the deprotonated form and available for absorption.

At pH 4.5, the ratio is:

4.5 = 2.97 + log([A-]/[HA])

log([A-]/[HA]) = 1.53

[A-]/[HA] = 31.6

So, at pH 4.5, 97% of the aspirin molecules are in the deprotonated form and available for absorption.

Therefore, more aspirin will be available for absorption in the duodenum (97%) compared to the stomach (12%).

Answer: C)Deposition (gas to solid)

Explanation: According to the phase diagram, at room temperature (25°C) and 1 atm, the sample is in the gas phase.  As the temperature decreases to 80 K, it falls below the sublimation curve. T he sublimation curve represents the conditions at which a substance can change directly from a solid to a gas or from a gas to a solid without passing through the liquid phase.

Since the sample is in the gas phase at room temperature, cooling it to 80 K would cause it to go through the process of deposition, where the gas particles directly transform into a solid without first becoming a liquid.  This is indicated by the section of the phase diagram below the sublimation curve.

The order for reactant A is 2 and the order for reactant B is 1. For the first reaction, the overall order of the reaction is 3 and for the second reaction, the overall order of the reaction is 5.

The order of a reaction is the sum of the exponents in the rate law expression that relates the rate of a chemical reaction to the concentrations of the reactants.

To determine the order of each reactant, we need to compare the initial rates of reaction at different concentrations while keeping the concentration of the other reactant constant.

For reactant A:

Exp#1 (0.100 M A, 0.100 M B): initial rate = k(0.100)^2(0.100) = 0.001 k

Exp#2 (0.200 M A, 0.100 M B): initial rate = k(0.200)^2(0.100) = 0.004 k

Exp#3 (0.100 M A, 0.200 M B): initial rate = k(0.100)^2(0.200) = 0.002 k

We can see that when the concentration of A doubles (Exp#1 to Exp#2), the initial rate quadruples, which indicates that A is second order. When the concentration of B doubles (Exp#1 to Exp#3), the initial rate doubles, which indicates that B is first order.

Therefore, the order for reactant A is 2 and the order for reactant B is 1.

To determine the overall order of the reaction, we add the orders of the reactants:

Overall order = 2 (order of A) + 1 (order of B) = 3

Therefore, the overall order of the reaction is 3.

For the second reaction, we can see that the rate depends on the concentration of both reactants, and we cannot determine their individual orders without further information or experiments. However, we can determine the overall order of the reaction by adding the exponents of the concentration terms in the rate law:

Overall order = 1 + 4 = 5

Therefore, the overall order of the reaction is 5.

If we assume that the larger circle represents the Earth, then the diameter of the Earth would be 30 times the diameter of the smaller circle representing the moon. Let's say that the diameter of the smaller circle is x. Then the diameter of the larger circle (Earth) would be 30 times x or 30x.

To find the correct distance from Earth to the moon at this scale, we need to know the actual distance from Earth to the moon, which is approximately 238,855 miles or 384,400 kilometers. If we divide this distance by the scale factor of 30, we get:

This is an exercise in specific heat and thermal conductivity which are two important physical properties that describe how materials interact with heat. Specific heat refers to the amount of energy required to raise the temperature of a material by a given amount, while thermal conductivity refers to a material's ability to transfer heat through itself.

The formula for specific heat is Q = mcΔT, where Q is the amount of heat transferred, m is the mass of the material, c is the specific heat, and ΔT is the change in temperature. The unit of measure for specific heat is J/(g*°C).

On the other hand, thermal conductivity is measured in terms of the amount of heat that is transferred through a material per unit time and area, given a temperature difference. It is expressed as the amount of heat transferred per second, per square meter, per meter of material thickness, when the temperature difference between the extremes is one Kelvin. Its formula is Q/t = -kA(∆T/∆x), where Q/t is the heat transfer rate, k is the thermal conductivity, A is the cross-sectional area, ∆T is the temperature difference, and ∆ x is the thickness of the material.

These properties are useful for understanding how materials interact with heat in a variety of situations, from building design to heating and cooling equipment manufacturing.

Now to calculate the temperature rise of 485 g of liquid water when 14.5 kJ of heat is added to it, we can use the formula:

Q = mcΔT

We must know that it has a quantity of heat of 14.5 Kj, with a mass of 485 g. The specific heat capacity of water is 4.18 J/(g °C).

First, we need to convert the heat added to joules:

Q = 14.5 KJ × (1000 J/1 KJ)

Q = 14500 J

We can then solve for ΔT. We clear the formula.

ΔT = Q / (m × c)

We substitute our data in the formula and solve the temperature change:

ΔT = Q / (m × c)

ΔT = (14500 J)/(485 g × 4.18 J/(g·°C))

ΔT ≈ 7.15 °C

The water would increase its temperature by approximately 7.15°C if 14.5 kJ of heat were added.

The percent yield of copper(I) sulfide in this experiment is 31.83%.

What is percent yield?

To calculate the percent yield, we need to compare the actual yield (the amount of product that was obtained in the experiment) with the theoretical yield (the amount of product that should have been obtained if the reaction had gone to completion).

The balanced chemical equation for the reaction between copper and sulfur to form copper(I) sulfide is:

Cu + S →  [tex]Cu_{2}S[/tex]

The molar mass of Cu is 63.55 g/mol, and the molar mass of S is 32.06 g/mol. The molar mass of  [tex]Cu_{2}S[/tex]  is 159.17 g/mol.

First, we need to calculate the theoretical yield of copper(I) sulfide using the amount of copper used in the experiment:

5 g Cu × (1 mol Cu / 63.55 g Cu) × (1 mol [tex]Cu_{2}S[/tex] / 1 mol Cu) × (159.17 g  [tex]Cu_{2}S[/tex] / 1 mol [tex]Cu_{2}S[/tex] ) = 12.57 g  [tex]Cu_{2}S[/tex]

So the theoretical yield of copper(I) sulfide is 12.57 g.

The actual yield obtained in the experiment is 4 g.

The percent yield is then:

percent yield = (actual yield / theoretical yield) × 100%

percent yield = (4 g / 12.57 g) × 100%

percent yield = 31.83%

Therefore, the percent yield of copper(I) sulfide in this experiment is 31.83%.

What is theoretical yield ?

The theoretical yield is the amount of product that would be obtained in a chemical reaction if it went to completion, meaning that all the limiting reactant was used up and no product was lost. It is calculated using stoichiometry, which involves balancing the chemical equation for the reaction and using the coefficients to determine the mole ratio between the reactants and products.

Theoretical yield is often used as a reference value to compare with the actual yield obtained in an experiment, which is the amount of product actually obtained from the reaction. The percent yield can then be calculated by dividing the actual yield by the theoretical yield and multiplying by 100%.

The above is about the movement of lithospheric plates. See explanation and attached image for details.

The movement of lithospheric plates is driven by convection currents in the Earth's mantle, which are caused by heat generated from the Earth's core. These currents cause the lithospheric plates to move, and the motion can result in a variety of geological phenomena, including earthquakes, volcanic activity, and the formation of mountain ranges and oceanic trenches.

There are three main types of plate boundaries, and each one results in a different type of movement of lithospheric plates:

Divergent Boundaries: At divergent boundaries, lithospheric plates move away from each other. This movement is caused by the upwelling of hot material from the mantle, which pushes the plates apart. As the plates move away from each other, magma rises up to fill the gap between them, creating new crust. Divergent boundaries are where new oceanic crust is formed.

Convergent Boundaries: At convergent boundaries, lithospheric plates move towards each other. There are three types of convergent boundaries: oceanic-oceanic, oceanic-continental, and continental-continental. At oceanic-oceanic and oceanic-continental convergent boundaries, one plate is forced beneath the other, creating a subduction zone. This movement is caused by the sinking of a denser plate beneath a less dense plate. As the denser plate sinks, it melts and can trigger volcanic activity. At continental-continental convergent boundaries, the plates are too buoyant to subduct, so they instead buckle and push up, forming mountain ranges.

Transform Boundaries: At transform boundaries, lithospheric plates move past each other. This movement is caused by the lateral movement of the convection currents in the mantle. Transform boundaries can create large faults, which can lead to earthquakes.

Overall, the movement of lithospheric plates is a complex and dynamic process, driven by the movement of material within the Earth's mantle.

System entropy = -80.8 J/K Surrounding entropy = 253.7 J/K The universe's entropy is 172.9 J/K. The reaction is unplanned. The procedure is a natural one.

Entropy is a measure of energy quality in the way that as lower the entropy, the more desirable the energy. Energy stored in a well-organized manner (the efficient library has a lower entropy. The entropy of energy contained in a chaotic manner (the random-pile library) is high.

Entropy is a gauge of a system's randomness or disorder. Entropy is greater in gases than in liquids, and greater in liquids than in solids. Order and disorder are important concepts in physical systems also known as randomness.
