Answer:

30 g/mol

Explanation:

Step 1: Given data

Step 2: Calculate the moles corresponding to 11.2 L of gas

At normal temperature and pressure (1 atm, 293.15 K), 1 mol of a gas has a volume of 24.05 L.

11.2 L × 1 mol/24.05 L = 0.466 mol

Step 3: Calculate the molecular mass of the gas

0.466 moles of the gas weigh 14 g. The molecular mass is:

M = 14 g/0.466 mol = 30 g/mol

Answer:

vapor pressure of methanol at 12.0C = 75.09 torr

Explanation:

Using Clausius Clapeyron equation

, we have that

ln (P2/P1)= (ΔHvap /R) (1/T1 - 1/T2)

Given

At Normal boiling point,

Temperature T1= 64.6°C = 64.6 + 273 = 337.6 K, Pressure,P1 = 1 atm

Heat of vaporization  = 35.2 kJ/mol

Changing to  J/mol

=35.2 x 1000= 35200 J/mol

Temperature , T2 = 12.0oC = 12 + 273 = 285 K

Using gas constant, R = 8.314 J/mol.K

ln (P2/P1)= -(ΔHvap /R) (1/T1 - 1/T2)

ln (P2/ 1 atm) = (35200 J/mol/ (8.314 J/mol.K) X( 1/337.6 - 1/285)

ln (P2/ 1 atm) =4,233.822 X (0.00296-0.003508)

ln (P2/ 1 atm)  = 4,233.822468  x-0.0005466866

ln (P2/ 1 atm)=  -2.31457

P2 = e^⁻2.31457 x 1 atm

P2=0.098808atm

= 0.098808atm  x760 = 75.09 torr

Answer:

You are right, it is the Engineer

Explanation:

Answer:

ΔH°rxn = -780kJ

Explanation:

It is possible to find enthalpy change of a reaction by the sum of analogue reactions (Hess's law).

Using the reactions:

1. 2Al(s) + 3/2O2(g) → Al2O3(s)  ΔH°rxn = −1601 kJ/mol

2. 2Fe(s) + 3/2O2(g) → Fe2O3(s)  ΔH°rxn = −821 kJ/mol

1 - 2:

2Al(s) + Fe2O3(s) → Al2O3(s) + 2Fe(s)

ΔH°rxn = ΔH°rxn(1) - ΔH°rxn(2)

ΔH°rxn = −1601 kJ/mol - (-821 kJ/mol)

ΔH°rxn = -780kJ

Considering the Hess's Law, the enthalpy change for the reaction is -780 kJ.

Hess's Law indicates that the enthalpy change in a chemical reaction will be the same whether it occurs in a single stage or in several stages. That is, the sum of the ∆H of each stage of the reaction will give us a value equal to the ∆H of the reaction when it occurs in a single stage.

In this case you want to calculate the enthalpy change of:

2 Al(s) + Fe₂O₃(s) → 2 Fe(s) + Al₂O₃(s)

which occurs in two stages.

You know the following reactions, with their corresponding enthalpies:

Equation 1:  2 Al(s) + [tex]\frac{3}{2}[/tex] O₂(g) → Al₂O₃(s)      ΔH = −1601 kJ/mol  

Equation 2:  2 Fe(s) + [tex]\frac{3}{2}[/tex] O₂(g) → Fe₂O₃(s)      ΔH = −821 kJ/mol

Because of the way formation reactions are defined, any chemical reaction can be written as a combination of formation reactions, some going forward and some going back.

To obtain the enthalpy of the desired chemical reaction you need 2 moles of Al(s) on reactant side and it is present in first equation so let's write this as such.

Now, 1 mole of Fe₂O₃(s)   must be a reactant and is present in the second equation. Since this equation has 1 mole of Fe₂O₃(s)   on the product side, it is necessary to locate the Fe₂O₃(s)  on the reactant side (invert it). When an equation is inverted, the sign of ΔH also changes.

You know that two equations with their corresponding enthalpies are:

Equation 1:  2 Al(s) + [tex]\frac{3}{2}[/tex] O₂(g) → Al₂O₃(s)      ΔH = −1601 kJ/mol  

Equation 2:  Fe₂O₃(s)  → 2 Fe(s) + [tex]\frac{3}{2}[/tex] O₂(g)   ΔH = 821 kJ/mol

Adding or canceling the reactants and products as appropriate, and adding the enthalpies algebraically, you obtain:

2 Al(s) + Fe₂O₃(s) → 2 Fe(s) + Al₂O₃(s)     ΔH= -780 kJ

Finally, the enthalpy change for the reaction is -780 kJ.

The mass of a single bromine molecule, Br₂ is 2.654 x 10⁻²² g.

Bromine is a diatomic element. It has a symbol Br and the atomic number is 35. Bromine is a naturally occurring element which is liquid at room temperature.

Molar mass of Br₂ is 159.808 g/mol. The molar mass of bromine is 79.904 g/mol. In Br₂, there are two bromine atoms.

To calculate the mass of a single bromine molecule -

In 1 mole of Br₂, there is Avogadro's number of molecules.

Avogadro's number = 6.022 x 10²³

Therefore, 1 mole = 6.022 x 10²³

1 mole of bromine has mass of 79.9 g/mol

So, it gives us -

1/6.022 x 10²³ = 1.66 x 10²³/79.9 = 2.654 x 10⁻²²g

For the mass of a single bromine molecule, Br₂ = 2.654 x 10⁻²² g

Answer:

λ = 0.029×10² m

f = 0.57×10¹⁷ s⁻¹

Explanation:

Given data:

Wavelength of wave = ?

Frequency of wave = 102.7×10⁶ s⁻¹

Solution:

Formula:

Speed of wave = Wavelength  × Frequency

speed of wave = 3×10⁸ m/s

by putting values,

3×10⁸ m/s = λ × 102.7×10⁶ s⁻¹

λ = 3×10⁸ m/s /  102.7×10⁶ s⁻¹

λ = 0.029×10² m

2nd)

Given data:

Wavelength of wave = 5.267 nm (5.267×10⁻⁹ m)

Frequency of wave =  ?

Solution:

Formula:

Speed of wave = Wavelength  × Frequency

speed of wave = 3×10⁸ m/s

by putting values,

3×10⁸ m/s = 5.267×10⁻⁹ m × f

f = 3×10⁸ m/s /  5.267×10⁻⁹ m

f = 0.57×10¹⁷ s⁻¹
