Answer:
69.86 slugs
Explanation:
From the ideal gas equation
PV = nRT
n (number of moles) = PV/RT
P is pressure of the gas = 30 atm = 30×101325 = 3,039,750 Pa
V is volume of the gas = 1000 ft^3 = 1000/3.2808^3 = 28.32 m^3
R is gas constant = 8.314 J/mol.K
T is the temperature of the gas = 530 R = 5/9 × 530 = 294.44 K
n = 3,039,750×28.32/8.314×294.44 = 35166.11 mol
mass = n× MW
MW of air = 29 g/mol
mass = 35166.11 × 29 = 1019817.19 g × 0.0685 slug/1000 g = 69.86 slugs
Answer:
The electrons in oxygen are paired while in nitrogen, they are not.
Explanation:
To analyse this we start with writing out the ground state electronic configurations for both elements.
Oxygen: 1s²2s²2p4 meaning the p subshell has the following arrangement of electrons ↑↓ ↑ ↑
Nitrogen : 1s²2s²2p³ meaning the p subshell has the following arrangement of electrons ↑ ↑ ↑
Clearly the paired electron in oxygen will be experiencing repulsion from the electron it shares an orbital with causing it to be removed easily. The electrons in nitrogen are unpaired, each orbital is singly occupied
Answer:
Although the Earth has a lesser mass than the Sun, it is far closer to you, allowing for a stronger pull.
