Answer:

Answer: 3.45 moles Li contains 2.08 × 10 (to the power of)24 atoms . Explanation: The relationship between atoms and moles is:. 1 mole atom. =6.022

Answer:

\(\boxed {\sf 5.63 \times 10^{24} \ atoms \ Li}}\)

Explanation:

We are asked to find how many atoms are in 9.35 moles of lithium (Li)

Moles are converted to atoms using Avogadro's Number or 6.022×10²³. This is the number of particles (atoms, molecules, formula units, etc.) in 1 mole of a substance. In this case, the particles are atoms of lithium.

We convert using dimensional analysis, so we set up a conversion factor using Avogadro's Number.

\(\frac {6.022 \times 10^{23} \ atoms \ Li}{1 \ mol \ Li}\)

We are converting 9.35 moles of lithium to atoms, so we multiply the conversion factor by this value.

\(9.35 \ mol \ Li *\frac {6.022 \times 10^{23} \ atoms \ Li}{1 \ mol \ Li}\)

The units of moles of lithium cancel.

\(9.35 *\frac {6.022 \times 10^{23} \ atoms \ Li}{1 }\)

\(9.35 *{6.022 \times 10^{23} \ atoms \ Li}\)

\(5.63057\times10^{24} \ atoms \ Li\)

The original value of moles (9.35) has 3 significant figures, so our answer must have the same. For the number we found that is the hundredth place. The 0 in the thousandth place tells us to leave the 3 in the hundredth place.

\(5.63 \times 10^[24} \ atoms \ Li\)

9.35 moles of lithium contains approximately 5.63×10²⁴ atoms of lithium.

The relation between the volume and the temperature of the gas is given by Charles's law. The final temperature of the gas at 0.75 liters is -193.8°C.

Charles's law was derived from the ideal gas equation and is used to state the relationship between the temperature and the volume of the gas. With a decrease in volume the temperature decreases.

If the pressure is kept constant then with an increase in temperature the volume of the gas expands. The law is given as,

V₁ ÷ T₁ = V₂ ÷ T₂

Given,

Initial volume (V₁) = 2.80 L

Initial temperature (T₁) = 23 °C = 296.15 K

Final volume (V₂) = 0.75 L

Final temperature = T₂

Substituting the values above as:

T₂ = (V₂ × T₁) ÷ V₁

= 0.75 × 296.15 ÷ 2.80

= 79.325 K

Kelvin is converted as, 79.325K − 273.15 = -193.8°C

Therefore, the final temperature is -193.8°C.

The strongest ion-dipole interaction with water is T13+ than Cd²+ than Na+.

An ion-dipole interaction is defined as the intermolecular force of attraction present between the charged ion (anion or cation) and the molecule. It is mainly found in the solution where the ionic compounds dissolved in the polar solvents.

The strength of ion-dipole interactions is mainly dependent on the distance and the charge. Ionic charge goes on increasing moving across a period on the periodic table.

Since, charge on Ti is 3 and greater than Cd which is greater than Na.

The balloon will be filled by a gas, and as the gas is not escaping we can assume that it is at a constant pressure.

The KMT (Kinetic Molecular Theory) explains the macroscopic properties of gases. This theory states that gases are formed by particles in constant motion, and that their kinetic energy is directly proportional to the temperature of the gas.

If we leave the balloon filled with gas in the sun we assume that the temperature of the gas inside will start to rise. When the temperature starst to rise, and the pressure is constant, particles will gain kinetic energy. This will result in particles moving faster and coliding with each other and with the balloon's walls more often. As a consecuence the particles will tend to stay farther from one another and the volume of the balloon will increase.

This is an example of Charles's Law that states that at constant pressure the volume of a gas is directly proportional to its temperature. In other words, when the temperature of the gas increases the volume increases as well.

To summarize, if we fill a balloon and we leave it in the sun its volume will increase.

Answer:

the correct answer is (a) Kc > 1.

The ratio of the concentrations of the products to the reactants, with each concentration increased to the power of its stoichiometric coefficient, determines the equilibrium constant (Kc) in a chemical reaction.

It is implied that the forward reaction is preferred and moves along more quickly than the reverse reaction in the case presented when the forward reaction rate constant is larger than the reverse reaction rate constant. This implies that the concentration of the products relative to the reactants will be higher at equilibrium.

Consequently, the following is the accurate statement on the equilibrium constant (Kc): (a) Kc > 1

Since the ratio of product concentrations to reactant concentrations, which determines Kc, is favoured in this situation and the products, the equilibrium  constant will be greater than 1.

134.6 °F

Explanation

To covert degrees C to degrees F use:

(0°C × 9/5) + 32 = 32°F

(57.0°C x 9/5) + 32 = 134.6 °F

To determine the universal gas constant (R), we can use the ideal gas law equation: PV = nRT, where P is the total pressure, V is the volume of gas, n is the number of moles, R is the universal gas constant, and T is the temperature in Kelvin.

Barometric pressure of the room: To find the barometric pressure in atm, we convert 766.86 mmHg to atm by dividing it by 760 mmHg/atm, giving us 1.0089 atm.Vapor pressure of water at room temperature (PH2O).The vapor pressure of water at 23.0°C is 0.0313 atm.

Mass difference of butane lighter:The mass difference is calculated by subtracting the initial mass (54.24 g) from the final mass (54.01 g), resulting in a difference of 0.23 g.

Moles of butane gas collected:To find the moles of butane gas, we can use the equation n = m/M, where n is the number of moles, m is the mass, and M is the molar mass of butane (58.12 g/mol). Thus, n = 0.23 g / 58.12 g/mol = 0.003959 mol.

Partial pressure of butane gas:The partial pressure of butane gas is calculated by multiplying the moles of butane gas (0.003959 mol) by the ideal gas constant (R) and the converted temperature (23.0°C + 273.15 K). Let's assume the converted temperature is 296.15 K.

Converted volume of gas collected:The volume of gas collected is given as 100.0 mL, which needs to be converted to liters by dividing it by 1000, resulting in 0.1 L.

Experimental value of R:The experimental value of R can be determined by rearranging the ideal gas law equation to solve for R: R = (P - PH2O) * V / (n * T).

Accepted value of R:The accepted value of R is 0.0821 Latm/molK.

The percent error can be calculated using the formula: (|Experimental value - Accepted value| / Accepted value) * 100.

Factors contributing to percent error could include experimental error in mass measurements, inaccurate temperature measurements, and loss of gas during collection or transfer.

If the gas had not been corrected for the partial pressure of water, the value of R would be lower because the partial pressure of water would contribute to the total pressure, resulting in a smaller value for P in the ideal gas law equation.

To increase accuracy and decrease percent error, the experiment could be repeated multiple times to obtain an average value, use more precise measuring instruments, conduct the experiment in a controlled environment, and ensure accurate calibration of equipment.

The quantity of the top product is approximately 1483.4 kg/h, and the quantity of the bottom product is approximately 1116.7 kg/h.

We solve using the concept of material balances.

Given:

F = Feed rate of the solution (benzene + toluene) = 1500 kg/h

Fb = Feed rate of benzene in the feed = 0.75 * F = 1125 kg/h

Ft = Feed rate of toluene in the feed = F - Fb = 375 kg/h

Benzene Balance:

Fb = Bt + Bb

where Bt is the flow rate of benzene in the top product and Bb is the flow rate of benzene in the bottom product.

1125 kg/h = Bt + Bb

Toluene Balance:

The mass balance equation for toluene can be written as:

Ft = Tt + Tb

where Tt is the flow rate of toluene in the top product and Tb is the flow rate of toluene in the bottom product.

375 kg/h = Tt + Tb

The reflux ratio is given as 2.5 kg reflux per kg of product

The total product flow rate (Pt) will be:

Pt = Bt + Tt = Bb + Tb

Therefore, the reflux flow rate (R) is:

R = 2.5 * Pt

Solving the equations, we find:

Bt = 1116.7 kg/h

Tb = 8.3 kg/h

Top Product Flow Rate = Bt + Tt = Bt + (Ft - Tb) = Bt + (375 - 8.3) = 1116.7 + 366.7 = 1483.4 kg/h

Explanation:

We'll begin by converting 250 tonnes to grams (g). This can be obtained as follow:

1 tonne = 1×10⁶ g

Therefore,

250 tonne = 250 × 1×10⁶

250 tonne = 2.5×10⁸ g

Next, the balanced equation for the reaction.

CaCO₃ —> CaO + CO₂

Next, we shall determine the mass of CaCO₃ that decomposed and the mass CaO produced from the balanced equation. This can be obtained as follow:

Molar mass of CaCO₃ = 40 + 12 + (16×3)

= 40 + 12 + 48

= 100 g/mol

Mass of CaCO₃ from the balanced equation = 1 × 100 = 100 g

Molar mass of CaO = 40 + 16

= 56 g/mol

Mass of CaO from the balanced equation = 1 × 56 = 56 g

SUMMARY:

From the balanced equation above,

100 g of CaCO₃ decomposed to produce 56 g of CaO.

Finally, we shall determine the mass of CaO produced by the decomposition of 250 tonnes (i.e 2.5×10⁸ g) of CaCO₃. This can be obtained as follow:

Answer: when concentrations of acid and base are same, pH = pKa

PH = 12.38 pOH = 1.62

Explanation: pKa= -log(Ka)= 12.38. PH + pOH = 14.00

The pH of the solution is 12.38 and the pOH of the solution is  1.62.

Using the Henderson Hasselbalch equation;

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

Where;

pKa = - log Ka = -log[ 4.2x10-13] = 12.38

[A-] = [PO43–] = 0.285 M

[HA] = [HPO42-] = 0.285 M

Substituting values;

pH =  12.38 + [ 0.285 M]/[ 0.285 M]

pH = 12.38

\(\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}\) ......(1)

Given mass of glucose = 46.8 g

Molar mass of glucose = 180 g/mol

Plugging values in equation 1:

\(\text{Moles of glucose}=\frac{46.8g}{180g/mol}=0.26 mol\)

Given mass of methanol = 117 g

Molar mass of methanol = 32 g/mol

Plugging values in equation 1:

\(\text{Moles of methanol}=\frac{117g}{32g/mol}=3.66 mol\)

Mole fraction is defined as the moles of a component present in the total moles of a solution. It is given by the equation:

\(\chi_A=\frac{n_A}{n_A+n_B}\) .....(2)

where n is the number of moles

Putting values in equation 2:

\(\chi_{methanol}=\frac{3.66}{0.26+3.66}=0.934\)

Raoult's law is the law used to calculate the partial pressure of the individual gases present in the mixture. The equation for Raoult's law follows:

\(p_A=\chi_A\times p_T\) .....(3)

where \(p_A\) is the partial pressure of component A in the mixture and \(p_T\) is the total partial pressure of the mixture

We are given:

\(p_{methanol}=122.7torr\\\chi_{methanol}=0.934\)

Putting values in equation 3, we get:

\(122.7torr=0.066\times p_T\\\\p_T=\frac{122.7torr}{0.934}=131.37torr\)

Hence, the total partial pressure of the solution is 131.37 torr.

Where:

Q = heat energy absorbed or released

m = mass of the substance

c = specific heat capacity of the substance

ΔT = change in temperature

In this case, 800 J of heat is absorbed by 120 g of water at 25 °C. We need to find the final temperature at equilibrium.

Using the equation for water:

Q_water = m_water * c_water * ΔT_water

Rearranging the equation, we can solve for the change in temperature (ΔT_water):

ΔT_water = Q_water / (m_water * c_water)

Substituting the given values:

ΔT_water = 800 J / (120 g * 4.18 J/g°C)

Calculating:

ΔT_water ≈ 1.525 °C

To find the final temperature at equilibrium, we add the change in temperature to the initial temperature:

Final temperature = 25 °C + 1.525 °C

Final temperature ≈ 26.525 °C

Therefore, the final temperature at equilibrium will be approximately 26.525 °C.

NiCl₂ and NaOH are both electrolytes, which means that they dissociate in water to form ions, which are charged particles that can conduct electricity.

When NiCl₂ is dissolved in water, it dissociates into Ni²⁺ ions and Cl⁻ ions. The conductivity of a dilute solution of NiCl₂ is relatively low because there are fewer ions present in the solution, and thus fewer ions available to conduct electricity.

When the concentration of NiCl₂ is increased, the conductivity of the solution also increases. This is because as the concentration of the solution increases, there are more ions present in the solution, which results in a greater ability to conduct electricity.

Similarly, when NaOH is dissolved in water, it dissociates into Na⁺ ions and OH⁻ ions. As with NiCl₂, the conductivity of a dilute solution of NaOH is relatively low because there are fewer ions present in the solution. As the concentration of NaOH is increased, the conductivity of the solution increases because there are more ions present in the solution.

In summary, the conductivity of dilute solutions of NiCl₂ and NaOH is low because there are fewer ions present in the solution. As the concentration of these solutions increases, the conductivity increases because there are more ions present in the solution.

The law of conservation of mass states that in a chemical reaction, the total mass of the reactants is equal to the total mass of the products. To provide evidence for this law, we can perform an experiment in which calcium carbonate (\(CaCO_3\)) is decomposed to produce calcium oxide (CaO) and carbon dioxide (\(CO_2\) ), and then measure the masses of the reactants and products.

Method:

Weigh a sample of \(CaCO_3\) using a balance.

Heat the \(CaCO_3\) in a crucible until it decomposes to CaO and \(CO_2\). The \(CO_2\) gas will escape, leaving only CaO in the crucible.

Allow the crucible to cool and then weigh it again to determine the mass of the CaO produced.

Collect the \(CO_2\) gas that is released during the reaction in a gas syringe or other collection device. Measure the volume of \(CO_2\) gas produced, and calculate its mass using its molecular weight.

Which measurements should be taken:

The following measurements should be taken:

The mass of the \(CaCO_3\) used as a reactant.

The mass of the CaO produced as a product.

The volume of \(CO_2\) gas produced during the reaction.

The temperature and pressure of the \(CO_2\) gas to allow for the calculation of its mass.

How the student could show evidence for the conservation of mass:

To show evidence for the law of conservation of mass, the student can compare the mass of the \(CaCO_3\) used as a reactant to the total mass of the products, which includes the mass of CaO produced and the mass of \(CO_2\) gas released.

The sum of the masses of CaO and \(CO_2\) should be equal to the mass of the \(CaCO_3\) used as a reactant, within experimental error. This will provide evidence that the mass of the reactants is conserved and equals the mass of the products, as required by the law of conservation of mass.

Additionally, the student could calculate the theoretical yield of CaO and CO2 based on the balanced equation for the reaction, and compare this to the actual yield obtained from the experiment. Any difference between the theoretical and actual yields could be due to experimental error, but the comparison can still provide additional evidence for the conservation of mass.
