How many moles of gas does it take to occupy 120 L at a pressure of 233 kPa and a temperature of 340 K?
2 answers:
Answer:
The correct answer is option D.
Explanation:
Using ideal gas equation:
PV = nRT
where,
P = Pressure of gas = 233 kPa
1 atm = 101.325 kPa
V = Volume of gas = 120 L
n = number of moles of gas = ?
R = Gas constant = 0.0821 L.atm/mol.K
T = Temperature of gas = 340 K
Putting values in above equation, we get:

The relation between the shielding and effective nuclear charge is given as
where s denote shielding
z_{eff} denote effective nuclear charge
Z - atomic number
Explanation:
shielding is referred to as the repulsion of an outermost electron to the pull of electron from valence shell. Higher the electron in valence shell higher will be the shielding effects.
Effective nuclear charge is the amount of net positive charge that valence electron has.
