Answer:
a) 8×10²³ molecules of N2
Explanation:
Let us consider the same temperature and pressure of both sample are standard temperature and pressure.
Standard temperature = 273.15 K
Standard pressure = 1 atm
Number of moles of CO₂ = 0.107 mol
Volume of CO₂ = ?
Solution:
PV = nRT
R = general gas constant = 0.0821 atm.L /mol.K
1 atm × V = 0.107 mol × 0.0821 atm.L /mol.K × 273.15 K
1 atm × V = 2.4 atm.L
V = 2.4 atm.L/1 atm
V = 2.4 L
Volume of N₂:
Number of moles of N₂:
1 mole = 6.022 ×10²³ molecules
8×10²³ molecules × 1 mol / 6.022 ×10²³ molecules
1.33 mol
PV = nRT
R = general gas constant = 0.0821 atm.L /mol.K
1 atm × V = 1.33 mol × 0.0821 atm.L /mol.K × 273.15 K
1 atm × V = 29.83 atm.L
V = 29.83 atm.L/1 atm
V = 29.83 L
Answer:
An atom bonds to have eight valence electrons to become stable. ... The third shell would be empty so that the eight electrons in the second level would be outermost after the atom loses one electron.
Explanation:
Answer:
The correct answer is - option C. Law of superposition.
Explanation:
According to the law of superposition states that within a sequence of layers of natural sedimentary rock without any disturbance, the oldest layer is lies under the younger layers with ascending order in the sequence.
If a sedimentary rock has 4 layers as a, b, c and d where the younger layer d would be on top and the oldest layer a would be at the bottoms.
Thus, the correct answer is - option C.
