Answer:
The molar amount of the gas.
Explanation:
If the pressure, volume, and temperature of a gas are known than molar amount can be determine.
Formula:
PV = nRT
P = pressure
V = volume
R = general gas constant
T = temperature
n = number of moles
Example:
V = 2 L, P = 1 atm , T = 273 K , R = 0.0821 atm. L/mol.K
n = PV/RT
n = 1 atm. 2 L / 0.0821 atm. L/mol.K . 273 K
n = 2 / 22.413 /mol
n = 0.09 mol
the answer would be d!! hope this helps
Answer:
extensive hydrogen bonding
Explanation:
The high boiling points of water, hydrogen fluoride (HF) and ammonia (NH3) is an effect of the extensive hydrogen bonding between the molecules. The London dispersion force is caused by random and temporary changes in the polarity of atoms, caused by the location of the electrons in the atoms' orbitals.
Hope this helps :)
Chlorine is a halogen and is very reactive and unstable. If released in an elemental form (Cl2), it would react with other substances immediately. However, <span>chlorofluorocarbons (CFCs) which contain chlorine are unreactive and when released they eventually end up in the upper atmosphere still "intact". In the upper atmosphere, sunlight is more intense and is able to break apart CFC, releasing the highly reactive chlorine which in turns destroys ozone which is more abundant in the upper atmosphere (stratosphere). </span>
