At what celcius temperature does 0.750 mol of an ideal gas occupy a volume of 35.9 L at 114 kPa

382.75 is the temperature of the 0.750 mol of an ideal gas occupy a volume of 35.9 L at 114 kPa.

Explanation:

Given:

number of moles (n) = 0.750

volume of the gas = 35.9 litres

pressure on the ideal gas  = 114 kPa or 1.125 atm

R (gas constant) = 0.0821J/Kmole

Absolute temperature of gas in celcius =?

the equation for the ideal gas is

PV = nRT

putting the values in the above equation:

T = \frac{PV}{RT}

  = \frac{1.125 X 35.9}{0.75 X 0.0821}

   = 655.907

655.9 kelvin is the temperature of the ideal gas.

To convert this unit of kelvin into degree celcius:

K-273.15 = C

655.9 - 273.15

= 382.75 degrees

382.75  degrees celcius is the temperature of the ideal gas.

How many moles of sodium carbonate contain 1.773 × 1017 carbon atoms?
vesna_86 [32]

Answer:

  • 2.941 × 10⁻¹⁷ mol

Explanation:

1) Chemical formula of sodium carbonate: <em>Na₂CO₃</em>

2) Ratio of carbon atoms:

  • The number of atoms of C in the unit formula Na₂CO₃ is the subscript for the atom, which is 1 (since it is not written).

Hence, the ratio is 1 C atom / 1 Na₂CO₃ unit formula.

This is, there is 1 atom of carbon per each unit formula of sodium carbonate.

3) Calculate the number of moles in 1.773 × 10⁷ carbon atoms

  • Divide by Avogadro's number: 6.022 × 10²³ atoms / mol

  • number C moles  = 1.773 × 10⁷ atoms / (6.022 × 10²³ atoms/mol)

  • number C moles = 2.941 × 10⁻¹⁷ mol

Since, the ratio is 1: 1, the number of moles of sodium carbonate is the same number of moles of carbon atoms.

HELP ME PLEASE!!!

Answer:

A bonding that occurs between high electronegative atoms such are N, F, O and H atoms, is called a hydrogen bond. Hydrogen bond is a very strong bond. (C)

If hydrogen bonds are not formed between H atoms and N, F, O atom, then the atoms interact through dispersion forces (also known as london dispersion forces). Dispersion forces are weak and they are temporary forces formed by overlapping of orbitals. (B)

Which of the following is a heterogeneous mixture? [1] Cola [2] Brass Air Coffee with sugar stirred in [5] [3] Soil
Readme [11.4K]

Answer:

Soil is heterogeneous mixture of sand particles of different sizes, shape and of different compositions.

Explanation:

Homogeneous mixtures are defined as the mixtures in which components are evenly spread throughout the solution. The size and shape of the particles are similar in these mixtures.

For example : alloys, salt solution.

Heterogeneous mixtures are defined as the mixtures in which component are unevenly spread throughout the solution. The size and shape of the particles differ in these mixtures.

For example : sand in a water, soil etc.

Brass is an alloy homogeneous mixture of metals.

Air is a homogeneous mixture of gases.

Coffee with sugar stirred in is also homogeneous mixture.

Soil is a heterogeneous mixture of sand particles of different sizes, shape and of different compositions.
