The pressure exerted by 0.400 moles of carbon dioxide in a 5.00 Liter container at 25 °C would be 1.9563 atm or 1486.788 mm Hg.
<h3>The ideal gas law</h3>
According to the ideal gas law, the product of the pressure and volume of a gas is a constant.
This can be mathematically expressed as:
pv = nRT
Where:
p = pressure of the gas
v = volume
n = number of moles
R = Rydberg constant (0.08206 L•atm•mol-1K)
T = temperature.
In this case:
p is what we are looking for.
v = 5.00 L
n = 0.400 moles
T = 25 + 273
= 298 K
Now, let's make p the subject of the formula of the equation.
p = nRT/v
= 0.400 x 0.08206 x 298/5
= 1.9563 atm
Recall that: 1 atm = 760 mm Hg
Thus:
1.9563 atm = 1.9563 x 760 mm Hg
= 1486.788 mm Hg
In other words, the pressure exerted by the gas in atm is 1.9563 atm and in mm HG is 1486.788 mm Hg.

The balanced chemical equation for the Haber-Bosch process is N₂(g) + 3H₂(g) → 2NH₃(g). The Haber-Bosch process played a significant role in boosting agriculture back in the day. It paved the way for the industrial production of ammonia which is used in the manufacture of fertilizers. The process involves reacting atmospheric N₂ with H₂ using a metal catalyst under high temperature and pressure.
Answer:
(a) Three translational degrees of freedom, 2 rotational degrees. 5 total
Cv = 5/2 R; Cp = 7/2 R
(b) and (c) 6 total degrees of freedom ( 3 translational, 3 rotational)
Cv = 3 R ; Cp = 4R
Explanation:
(a) O₂
Oxygen being a diatomic molecule has three translational degrees of freedom and two rotational degrees of freedom since it can move in the three axis and can rotate around two.
(b) H₂O
This is a polyatomic molecule and it has three translational and three rotational degrees of freedom.
(c) Same as water it has three translational degrees of freedom and three rotational degrees of freedom
To calculate the heat capacities we have to make use of the equipartition theorem which tell us that for each degree of freedom imparts 1/2 R to the heat capacity at constant volume.
(a)
5 total degrees of freedom ⇒ Cv = 5/2 R
Cp ( heat capacity at constant pressure) is determined from the relation
Cp - Cv = R
Cp = 7/2 R for O2 molecule
(b) and (c)
Total degrees of freedom 6
Cv = 3 R
Cp = 4 R
Here we are ignoring any contribution of the vibrational modes to the contribution of the heat capacities
The reagent in the chemical reaction which oxidizes other reactants but itself reduces are called oxidizing agent.
