Answer:
P = 2.92 atm
Explanation:
With the three assumptions in mind, the system consists of:
- A liquid phase containing n-hexane and n-heptane, and
- A gaseous phase containing n-hexane vapor, n-heptane vapor, and nitrogen gas.
First we use PV=nRT to calculate the moles of n-hexane and n-heptane in the gaseous phase:
P = 0.199 MPa ⇒ 0.199 * 1.869 = 1.964 atm
- 1.964 atm * 648 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 365 K
P = 0.083 MPa ⇒ 0.083 * 1.869 = 0.155 atm
- 0.155 atm * 648 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 365 K
So <u>the gaseous phase consists of 42.52 moles of n-hexane, 3.358 moles of n-heptane, and 14 mol of nitrogen</u>.
For the liquid phase, we <u>calculate the remaining moles of n-hexane and n-heptane</u>. Then we<u> convert to liters</u>, using their molar volumes:
- n = 112 mol - 42.52 mol = 69.48 mol
- 69.48 mol * 0.146 L/mol = 10.14 L
- n = 155 mol - 3.358 mol = 151.642 mol
- 151.642 mol * 0.162 L/mol = 24.57 L
So the liquid phase occupies (10.14+24.57) = 34.71 L, and <u>contains 69.48 mol of n-hexane and 151.64 mol of n-heptane</u>.
Finally, to<u> calculate the pressure in the vessel</u>, we use PV=nRT:
P = ?
V = 648 - 34.71 = 613.29 L
n = 42.52 mol hexane + 3.35 mol heptane + 14 mol nitrogen = 59.87 mol
T = 365 K
- P * 613.29 L = 59.87 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 365 K
The given gives an equation <span>4NH➡ 2N² + 6H². The equation given is not correct since H is not balanced. on the right side,H is counted as only 4 while on the right side, H is 12. The compound on the right should be ammonia, NH3 in order to balance the equation.</span>
An electron should emit energy to return to its original energy level from a higher energy level.
<h3>What is an energy level?</h3>
Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found.
The electron absorbs the energy and jumps to a higher energy level. In the reverse process, emission, the electron returns to the ground state by releasing the extra energy that is absorbed.
Hence, an electron should emit energy to return to its original energy level from a higher energy level.
