Pentanone, because it will boil at around 100 to 102 degree C, about the same as water, while propane boils at about -42 degree C, a temperature way below both pentanone and water's freezing point.

Cost of production reports can also be used to compare the materials output quantity to the a.administrative staff input quantit
valentinak56 [21]

Answer:

b.materials input quantity

Explanation:

A cost of production report shows the following:

  • total and unit costs transferred from preceding department
  • materials, labor , factory Overhead added by the department
  • unit costs added by the department
  • total and unit costs accumulated to the end of operations
  • the cost of beginning and ending work in process inventories
  • the cost transferred to the next department

A cost of production report determines periodic total and unit costs.

Either in the cost of production report or in the supporting schedule each item of material used is listed, every labor operation is shown separately,factory overhead components are noted individually, and a unit cost is derived for each item.

A Quantity Schedule Of Cost of Production report  shows the following

  • units started in process
  • units transferred to next department
  • units still in process
  • units lost in process

jenyasd209 [6]

The question is incomplete, the complete question is;

A 8.00 L tank at 2.64 °C is filled with 9.82 g of chlorine pentafluoride gas and 10.1 g of dinitrogen difluoride gas. You can assume both gases behave as ideal gases under these conditions. Calculate the mole fraction and partial pressure of each gas, and the total pressure in the tank. Be sure your answers have the correct number of significant digits.

Answer:

See explanation for details

Explanation:

Number of moles of N2F2 = mass/ molar mass

Molar mass of N2F2 = 66 g/mol

Number of moles = 10.1 g/66 = 0.15 moles

Number of moles of ClF5 = 9.82 g/130 g/mol= 0.08 moles

Molar mass of ClF5= 130g/mol

Total number of moles = 0.15 moles + 0.08 moles = 0.23 moles

Given that;

T= 2.64 °C + 273 = 275.64 K

n= 0.23 moles

R= 0.082 Latmmol-1K-1

V= 8.00 L

P= ??

From;

PV =nRT

P= nRT/V

P= 0.23 ×0.082 × 275.64/8.00

P= 0.65 atm

Mole fraction of N2F2= 0.15/0.23 = 0.65

Partial pressure = mole fraction × total pressure = 0.65 × 0.65 = 0.42 atm

Mole fraction of ClF5 = 0.08/0.23 = 0.35

Partial pressure of ClF5 = mole fraction × total pressure = 0.35 × 0.65 = 0.22 atm

Why couple should use a method of birth control
Tresset [83]

Answer:

because it will control the birth of a child which can happen alot being overpopulated in the country or world.
