A tank at is filled with of dinitrogen monoxide gas and of dinitrogen difluoride gas. you can assume both gases behave as ideal gases under these conditions. calculate the partial pressure of each gas in the tank. round each of your answers to significant digits

Answers

Answer 1

Partial Pressure for dinitrogen monoxide gas is 187 kPa

Partial Pressure for sulfur tetrafluoride gas is 33.4 kPa.

To calculate partial pressure first we need to calculate number of moles (n).

Mole (n) = mass/molar mass

Number of moles of dinitrogen monoxide gas= 17.7/44 gram per mole = 0.4023.

n=0.4023

Number of moles of sulfur tetrafluoride= 7.77/108.1 = 0.07188 moles.

Pressure × volume = number of moles × gas constant, R × temperature.

Pressure = n × R × T/ V.

For dinitrogen monoxide gas -

Partial Pressure = 0.4023 × 8.314 × 280.03 / 5 × 10^-3 = 187 kPa.

Partial pressure of dinitrogen monoxide gas = 187kPa.

For sulfur tetrafluoride gas-

Partial Pressure = 0.07188 × 8.314 ( × 280.03 / 5 × 10^-3) = 33.4 kPa.

Partial pressure of sulfur tetrafluoride = 33.4kPa.

So, Partial pressure of dinitrogen monoxide gas = 187kPa.

Partial pressure of sulfur tetrafluoride = 33.4kPa.

Which statement best compares the melting points of magnesium and sodium?

a
Magnesium has a higher melting point because it contributes one additional electron per atom than sodium in the electron sea.
b
Sodium has a higher melting point because it contributes one fewer electron per atom than magnesium in the electron sea.
c
Sodium has a higher melting point because it contributes two fewer electrons per atom than magnesium in the electron sea.
d
Magnesium has a higher melting point because it contributes two additional electrons per atom than sodium in the electron sea.

Answers

A because according to electron sea theory magnesium shares two valence electrons in electron sea while sodium shares one suggesting that magnesium has stronger metallic bond than sodium so breaking metallic bond in magnesium will require more energy as compared to breaking metallic bond in sodium

The melting point of magnesium is higher than the melting point of sodium because it contributes two additional electrons per atom than sodium in the electron sea. Thus option d is correct.

What is melting point?

Melting point of a substance is the temperature at which it converts from solid state to liquid state where, the two phases are in equilibrium. Melting point is affected by the bond type, molecular weight, temperature and pressure.

Melting point of elements increases along a period because the atomic size is decreasing along the period and molecular weight is increasing. Thus, the nuclear attractive pull increases resulting in higher energy needed to break the attractive force.

Magnesium is 12th element and sodium is 11th element. Thus magnesium is smaller than sodium and have one more electron than sodium. Thus magnesium have high molecular weight and high nuclear attraction leads to its higher melting point.

A gas has a volume of 500cm3 when a pressure of 100,00N is exacted on it what will be it's volume if the pressure is changed to 150mm mecury at same temperature

Answers

Answer:

See explanation below

Explanation:

At first sight, it seems that the innitial pressure of 100,00 N would be 100,00 N/m² because pressure does not have units of newton alone. If this is true, then the calculations are the following (If it's not, but it's actually mm Hg, then skip the part of the conversion, and just do the procedure of solving for the volume).

The innitial pressure is 100 N/m² or simply 100 Pa. As the second pressure is in mm Hg, let's convert the Pascal units to mm Hg:

1 Pa -----> 0.007501 mm Hg

100 ---------> X

X = 100 * 0.007501 / 1 = 0.7501 mmHg

Now that we have the innitial pressure in mm Hg, and the temperature remains constant, we use the Boyle's law to solve for this:

P₁V₁ = P₂V₂

V₂ = P₁V₁ / P₂  

Using this expression, let's solve for V₂:

V₂ = 0.7501 *¨500 / 150

V₂ = 2.5 cm³

Now, it's the innitial pressure is 100 mm Hg then the volume:

V₂ = 100 * 500 / 150

V₂ = 333.33 cm³

Check the units of the innitial pressure, one of these results should be the correct answer. If it's not, then please post again the question with the correct units.

how many atoms of alumminum are in 3.9 mol of aluminum​

Answers

Answer:

2.35 x 10²⁴ atoms Al

Explanation:

Given 3.9 moles of aluminum (Al), determine number of aluminum atoms in that quantity of substance.

By definition a mole is the mass of substance containing one Avogadro's Number (N₀) of particles. That is, 1 mole = 1 N₀ = 6.023 x 10²³ particles*.

So, if 1 mole aluminum contains 6.023 x 10²³ atoms of aluminum then

3.9 moles Al = 3.9 moles Al  x  6.023 x 10²³ atoms Al/mole Al = 2.35 x 10²⁴ atoms Al.

________________

*The complete equivalent relationship is ...

1 mole (atoms or compounds) = 6.023 x 10²³ atoms or molecules = 1 formula weight of the substance = 22.4 Liters (if in gas phase at STP conditions (0°C and 1atm pressure).

calculate the volume occupied by 10g of propane gas, under normal conditions of temperature and pressure

Answers

Answer:

5.5 L

Explanation:

First we convert 10 g of propane gas (C₃H₈) to moles, using its molar mass:

10 g ÷ 44 g/mol = 0.23 mol

Then we use the PV=nRT formula, where:

P = 1 atm & T = 293 K (This are normal conditions of T and P)n = 0.23 molR = 0.082 atm·L·mol⁻¹·K⁻¹V = ?

1 atm * V = 0.23 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 293 K

V = 5.5 L

Which of these best describes the relationship between the inner core, outer core, mantle, crust, asthenosphere, and lithosphere?

A: The coolest layers are farthest from the core.

B: The least dense layers are closest to the core.

C: The layers with the highest concentration of metals are closest to the crust.

D: The layers that remain in a molten state are closest to the crust.

Answer:

The coolest layers are farthest from the core.

Explanation:

When we talk about the internal structure of Earth, we mean the subdivisions of the solid Earth, that is, the concentric spherical layers that marks out the structure of the solid Earth.

The inner core is the innermost part of the earth's core and is known to have extremely high temperature. This high temperature steadily decreases as you approach the earth's surface.

Hence, the coolest layers are farthest from the core.
