5. To meet production in August, 71,000 pounds of raw materials are needed.

Since each unit of finished goods requires 5 pounds of raw materials, we can calculate the number of units needed in August as 71,000 pounds / 5 pounds per unit = 14,200 units.

The ending To determine the answers to the questions, we need to calculate the required information based on the provided data. inventory in July is 10% of the following month's raw materials production needs, which is 10% of 14,200 units = 1,420 units. Since each unit requires 5 pounds of raw materials, the total pounds of raw materials to be purchased in July is 1,420 units * 5 pounds per unit = 7,100 pounds. 6. To calculate the estimated cost of raw materials purchases for July, we need to determine the cost per pound of raw materials. Given that the raw materials cost $2.00 per pound, the estimated cost of raw materials purchases for July is 7,100 pounds * $2.00 per pound = $14,200. 7. The total estimated cash disbursements for raw materials purchases in July can be calculated by considering the payment terms. Twenty percent of raw materials purchases are paid for in the month of purchase, and 80% are paid in the following month. Given that the cost of raw material purchases in June is $93,040, the payment made in July is 20% * $93,040 = $18,608. The payment made in August would be 80% * $93,040 = $74,432. Therefore, the total estimated cash disbursements for raw materials purchases in July would be $18,608. 8. To calculate the estimated accounts payable balance at the end of July, we need to consider the payment terms. Since 80% of raw materials purchases are paid in the following month, 80% * $14,200 = $11,360 will be paid in August. Therefore, the estimated accounts payable balance at the end of July would be $14,200 - $11,360 = $2,840. 9. The estimated raw materials inventory balance at the end of July can be calculated by considering the ending raw materials inventory in July. Given that the ending raw materials inventory equals 10% of the following month's raw materials production needs, which is 10% of 14,200 units = 1,420 units. Since each unit requires 5 pounds of raw materials, the estimated raw materials inventory balance at the end of July would be 1,420 units * 5 pounds per unit = 7,100 pounds. 10. To calculate the total estimated direct labor cost for July, we need to consider the number of units produced and the direct labor wage rate. The budgeted unit sales for July are 12,000 units. Each unit of finished goods requires 2 direct labor-hours, so the total direct labor-hours for July would be 12,000 units * 2 direct labor-hours per unit = 24,000 direct labor-hours. Given that the direct labor wage rate is $13 per hour, the total estimated direct labor cost for July would be 24,000 direct labor-hours * $13 per hour = $312,000.

5) 14,200 units of finished goods will be produced in August.

6) The estimated cost of raw materials purchases for July is  $2,800.

7) The total estimated cash disbursements for raw materials purchases in July is $18,608 + $74,432 = $93,040.

8) The estimated accounts payable balance at the end of July is  $59,546.40.

9)  Raw materials inventory balance is 700 pounds.

10) Total estimated direct labor cost for July is $312,000.

Let's solve  in detail:

5. To meet production in August, 71,000 pounds of raw materials are needed. Since each unit of finished goods requires 5 pounds of raw materials, the total number of units to be produced is 71,000 pounds / 5 pounds per unit = 14,200 units. Therefore, 14,200 units of finished goods will be produced in August.

6. If 7,000 pounds of raw materials are needed to meet production in August, and each unit of finished goods requires 5 pounds of raw materials, the total number of units to be produced is 7,000 pounds / 5 pounds per unit = 1,400 units.

The estimated cost of raw materials purchases for July is 1,400 units * $2.00 per pound = $2,800.

7. To calculate the total estimated cash disbursements for raw materials purchases in July, we need to consider the payment terms.

In July, 20% of raw materials purchases are paid for in the month of purchase, and 80% is paid in the following month.

The raw materials purchased in June amount to $93,040. Assuming 20% is paid in June, the cash disbursement for June is $93,040 * 20% = $18,608.

For the remaining 80% of the June purchases, which will be paid in July, we need to calculate the amount. This is given by 80% of the June purchases - 20% of the July purchases.

Amount to be paid in July = ($93,040 * 80%) - (Total purchases for July * 20%)

Solving for the Total purchases for July:

($93,040 * 80%) - (Total purchases for July * 20%) = Total purchases for July * 80%

Rearranging the equation:

($93,040 * 80%) = (Total purchases for July * 80% + Total purchases for July * 20%)

($93,040 * 80%) = Total purchases for July * 100%

Total purchases for July = ($93,040 * 80%) / 100%

Substituting the value of June purchases, we get:

Total purchases for July = ($93,040 * 80%) / 100% = $74,432

Therefore, the total estimated cash disbursements for raw materials purchases in July is $18,608 + $74,432 = $93,040.

8. If 7,000 pounds of raw materials are needed to meet production in August, and 80% of raw materials purchases are paid in the following month, the estimated accounts payable balance at the end of July would be 80% of the purchases for July.

Accounts payable balance = Total purchases for July * 80% = $74,432 * 80% = $59,546.40.

9. If 7,000 pounds of raw materials are needed to meet production in August, and the ending raw materials inventory equals 10% of the following month's raw materials production needs, the estimated raw materials inventory balance at the end of July would be 10% of the raw materials needed for August.

Raw materials inventory balance = 10% of the raw materials needed for August = 10% of 7,000 pounds = 700 pounds.

10. The total estimated direct labor cost for July can be calculated by multiplying the direct labor wage rate per hour by the total direct labor hours required for production in July.

Total direct labor hours for July = Number of units to be produced in July * Direct labor hours per unit = 12,000 units * 2 hours per unit = 24,000 hours.

Total estimated direct labor cost for July = Total direct labor hours for July * Direct labor wage rate = 24,000 hours * $13 per hour = $312,000.

Answer:

6 gallons of gasoline for $14.45 is the best price

Explanation:

26.29/11=2.39 $ per gallon

14.45/11=1.31 $ per gallon

Answer:

C. The electrons in each C-F bond will be more attracted to the fluorine atom.

The correct answer is B. NaHCO3 (sodium bicarbonate) is soluble in water because NaHCO3 is an ionic compound with polar characteristics, allowing it to dissolve in the polar solvent water..

Water is a polar solvent, meaning it has a partial positive and negative charge due to the uneven distribution of electrons between the hydrogen and oxygen atoms. Hexane (C6H14), on the other hand, is a nonpolar solvent, meaning it lacks any significant charge separation.
Solubility of a solute is determined by the principle "like dissolves like," which means that polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes.
The other options are incorrect because:
A. CaCl2 (calcium chloride) is soluble in water, not hexane, due to its polar nature as an ionic compound.
C. Octane (C8H18) is nonpolar and soluble in nonpolar solvents like hexane, not in polar solvents like water.
D. Mineral oil is nonpolar and soluble in nonpolar solvents, not in polar solvents like water.

Therefore, NaHCO3 (sodium bicarbonate) is soluble in water (Option b). This is because NaHCO3 is an ionic compound with polar characteristics, allowing it to dissolve in the polar solvent water.

Answer

%Yield = 87.2%

Explanation

Given:

mass of NH3 reacted = 73 g

mass of H2O produced = 101 g

We know:

molar mass of NH3 = 17,031 g/mol

molar mass of water = 18.01528 g/mol

Required: % Yield

Solution:

The formula used to calculate the percentage yield is:

%Yield = (actual yield/theoretical yield) x 100

The actual yield of H2O produced = 101 g

Now lets calculate the theoretical yield first.

First find the number of moles of NH3, and use stoichiometry to find the theoretical mass of water.

n = m/M n is the moles, m is the mass and M is the molar mass.

n = 73/17,031 g/mol

n = 4.29 mol

Using the stoichiometry, there molar ratio between NH3 and H2O is 4:6

Therefore the moles of H2O = 4.29 x (6/4)

n of H2O = 6.43 mol

The theoretical mass can then be calculated:

m = n x M

m = 6.43 mol x 18.01528 g/mol

m = 115.83 g

%Yield = (101 g/115.83)*100

%Yield = 87.2%

Answer:

10.28 mol

Explanation:

S + 2O = SO2

(atm x L) ÷ (0.0821 x K)

(3.45 x 45.6) ÷ (0.0821 x 373)

=5.13726

Then round it to significant figures

=5.14

5.14 mol SO2 x (2 mol O ÷ 1 mol SO2)

=10.28 mol O

The number of moles of oxygen atoms in 5.14 moles of SO₂ gas is equal to 10.28 mol.

The ideal gas law is used to describe an equation of the state of an ideal gas. The ideal gas equation can be defined as the product of the volume (V) and the pressure (P) of 1-mole ideal gas is equal to the product of the universal gas constant (R) and absolute temperature.

The ideal gas equation can be expressed in the mathematical form as follows:

PV = nRT

Where n is the moles of a gas, P is the pressure,  V is the volume of the gas,  and R is the universal gas constant.

Given, the volume of sulfur dioxide, V = 45.6 L

The temperature of SO₂ gas, T = 373 K

The universal gas constant, R =0.082 atmL /K mol

The pressure of the SO₂ gas, P = 3.45 atm

Substituting the values R, V, P, and T in the gas law equation, we get:

The number of moles of sulphur dioxide, n = PV/RT

n = 3.45 ×45.6/(0.082 × 373)

n = 5.14 mol

The number of moles SO₂ gas = 5.14

Moles of oxygen atoms in 5.14 moles of SO₂ = 2 × 5.14 = 10.28 mol

Answer:

Explanation:

The estimated enthalpy of triple bonds between nitrogen in a nitrogen molecule is -315kJ/mole.

To estimate the enthalpy of the triple bond between nitrogen atoms in an N2 molecule, we can use the enthalpies of formation of N2 and the individual nitrogen atoms, which are listed in Appendix C.

The enthalpy of formation (ΔHf) of a substance is the change in enthalpy when one mole of the substance is formed from its constituent elements in their standard states (usually at 25°C and 1 atm). For example, the enthalpy of formation of N2(g) is defined as:

N2(g) → 2N(g) ΔHf = 946 kJ/mol

This means that it takes 946 kJ of energy to form one mole of N2 from its constituent nitrogen atoms.

On the other hand, the enthalpy change for breaking the N2 molecule into two nitrogen atoms is equal in magnitude but opposite in sign to the enthalpy of formation of N2, because breaking a bond requires energy input.

Therefore, we have: N2(g) → 2N(g) ΔHf = -946 kJ/mol

To estimate the enthalpy of the triple bond, D(N‚N), we can assume that breaking the N2 molecule into two nitrogen atoms requires breaking three equivalent bonds, each with the same bond energy. Therefore:

D(N‚N) = ΔHf/N2 ÷ 3

Substituting the values, we get:

D(N‚N) = (-946 kJ/mol)/3

D(N‚N) = -315 kJ/mol

Therefore, the estimated enthalpy of the triple bond between nitrogen atoms in an N2 molecule is -315 kJ/mol. This means that breaking the N2 molecule into two nitrogen atoms requires an input of 315 kJ of energy per mole of N2. Conversely, forming an N2 molecule from two nitrogen atoms releases 315 kJ of energy per mole of N2.

The rate at which the nitrogen dioxide, NO₂ will effuse is 64 mL/s

This states that the rate of diffusion of a gas is inversely proportional to the square root of the molar mass i.e

R ∝ 1/ √M

R₁/R₂ = √(M₂/M₁)

Where

Applying the Graham's law of diffusion equation, we have:

R₁/R₂ = √(M₂/M₁)

82 / R₂ = √(46 / 28)

Cross multiply

82 = R₂√(46 / 28)
