Answer:
n = 0.271 moles
Explanation:
Given that,
Volume of container, V = 14 L
Pressure of Nitrogen gas, P = 375 torr
Temperature. T = 37°C=37+273=310°C
We need to find the number of moles of nitrogen in the container. Using gas equation,
PV = nRT
R is gas constant, R = 0.082 L-atm/mol-K
Since, 1 atm=760 torr
375 torr = 0.493 atm
Now,
So, there are 0.271 moles of Nitrogen in the container.
Answer:
Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract a shared pair of electrons (or electron density) towards itself. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus.
Explanation:
HCL + NaOH —> H2O + NaCl
It’s a double replacement reaction
The intermolecular forces that are responsible for the dissolution of Ethylene glycol in water is hydrogen bonding dipole-dipole forces and dispersion forces.
Both ethylene glycol and water contains the pair of hydrogen and oxygen.
The hydrogen of one atom create a bond with the oxygen of other atom this results in the formation of intra molecular hydrogen bonding.
The electron are non uniformly distributed over the molecule or the atom which results in the fluctuation of the electron density in the atom.
So it creates are dispersion forces which is present all over the molecule this forces helps to increase the strength of the bond formed between the ethylene glycol and water because they have large masses.
Both ethylene glycol and water are polar molecules because of being polar they form dipole and the dipole of both the molecules interact with each other in order to form bond between the atoms which eventually results in the formation dissolution of ethylene glycol in water.
