A tank has a total pressure of 285 kPa and contains Hydrogen, Oxygen, Carbon dioxide, and Neon. If Neon has a partial pressure o

f 14 kPa, carbon dioxide is 13 kPa, and Oxygen has a partial pressure of 157 kPa, what is the partial pressure of Hydrogen?

Answer:

Lets the total pressure is Pt and the individual gases are designated as pH2, pCO2, pNe, pO2.

Pt =  pCO2+ pNe+pO2+ pH2

285KPa = 13 KPa+ 14 KPa + 157 KPa +pH2

Now add the partial pressure of CO2, Ne and O2 which is equal to 184 KPa.

285 KPa = 184 KPa + pH2  

Now subtract the individual pressure of each gas from thje total pressure.

285 KPa - 184 KPa = pH2

                101 KPa = pH2

The partial pressure of hydrogen is  101 KPa.

Calculate the density of O2(g) at 415 K and 310 bar using the ideal gas and the van der Waals equations of state. Use a numerica
Lera25 [3.4K]

Answer:

Explanation:

From the given information:

The density of O₂ gas = d_{ideal} = \dfrac{P\times M}{RT}

here:

P = pressure of the O₂ gas = 310 bar

= 310 \ bar \times \dfrac{0.987 \ atm}{1 \ bar}

= 305.97 atm

The temperature T = 415 K

The rate R = 0.0821 L.atm/mol.K

molar mass of O₂  gas = 32 g/mol

∴

d_{ideal} = \dfrac{305.97 \ \times 32}{0.0821 \times 415}

d_{ideal} = 287.37 g/L

To find the density using the Van der Waal equation

Recall that:

the Van der Waal constant for O₂ is:

a = 1.382 bar. L²/mol²    &

b = 0.0319  L/mol

The initial step is to determine the volume = Vm

The Van der Waal equation can be represented as:

P =\dfrac{RT}{V-b}-\dfrac{a}{V^2}

where;

R = gas constant (in bar) = 8.314 × 10⁻² L.bar/ K.mol

Replacing our values into the above equation, we have:

310 =\dfrac{0.08314\times 415}{V-0.0319}-\dfrac{1.382}{V^2}

310 =\dfrac{34.5031}{V-0.0319}-\dfrac{1.382}{V^2}

310V^3 -44.389V^2+1.382V-0.044=0

After solving;

V = 0.1152 L

∴

d_{Van \ der \ Waal} = \dfrac{32}{0.1152}

d_{Van \ der \ Waal} = 277.77  g/L

We say that the repulsive part of the interaction potential dominates because the results showcase that the density of the Van der Waals is lesser than the density of ideal gas.

3. Why ionic bond is also known as electrovalent bond?​
Veseljchak [2.6K]

Answer:

ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
