Mass of Neon : = 24.21564 g
Given
1.2 moles of Neon
Required
mass of Neon
Solution
The mole is the number of particles contained in a substance
1 mol = 6.02.10²³
Moles can also be determined from the amount of substance mass and its molar mass
Mol = mass : Molar mass
so mass of Neon(MM=20,1797 g/mol) :
= mol x MM
= 1.2 x 20,1797
= 24.21564 g
eight
four
six
The answer is: four.
For example compound carbon dioxide (CO₂):
Electron configuration of carbon: ₆C 1s² 2s² 2p².
Electron configuration of oxygen: ₈O 1s² 2s² 2p⁴.
Carbon atom is sp2 hybridized, it has three sp2 orbitals and one p orbital, they form four bonds.
Oxygen has two p orbitals, they form two bonds (one sigma and one pi bond).
p orbitals from carbon and oxygen overlap and form pi bond.
(B) The equation is not balanced.
(C) The valence of the nitride ion is incorrect.
(D) The valance of the magnesium ion is incorrect.
(E) The coefficient of N₂ is incorrect.
Can someone explain this one?
b) It did not identify the distance between an electron and the nucleus.
c) It contradicted the Heisenberg uncertainty principle.
d) It stated that spectral lines of atoms are similar.
Answer: C
Explanation: Just took it
Boyle's law deals with pressure and volume.
Robert Boyle studied the relationship between the pressure p and the volume V of a confined gas held at a constant temperature.
Boyle observed that the product of the pressure and volume are observed to be nearly constant.
The product of pressure and volume is exactly a constant for an ideal gas.
PV = constant
As per Boyle’s law, any change in the volume occupied by a gas (at constant quantity and temperature) will result in a change in the pressure exerted by it. In other words, the product of the initial pressure and the initial volume of a gas is equal to the product of its final pressure and final volume (at constant temperature and number of moles).
Therefore, Boyle's law deals with pressure and volume.
