Answer:
Electronegativity is a measure of how strongly atoms attract bonding electrons to themselves.
Its symbol is the Greek letter chi: χ
The higher the electronegativity, the greater an atom's attraction for electrons.
Below is a periodic table of electronegativity: the lighter the shade of green, the higher the electronegativity. Gray means no value is known. (Click image for larger view that shows electronegativity values.)

Explanation:
The original calculation to find the number of moles which is 
can be rearranged to give the equation 
. Therefore the amount of molecules can be found by 
(multiplying by Avogadro's Number)
Answer:
600k
Explanation:
In this problem, we need to use a gas law that relates temperature to volume. The gas law to use here is the Charles’ law.
The Charles’ law posits that temperature and volume are directly proportional, provided that the pressure is kept constant.
Mathematically:
V1/T1 = V2/T2
We are looking at getting V2, hence we can write the mathematical equation as:
T2 = V2T1/V1
Asides the fact that we know that the gas is monoatomic, we do not know its volume. Let its initial volume be v. Since it expanded adiabatically, this means that its new volume is 2v
Hence: V1 = v , V2 = 2v , T1 = 300k and T2 is ?
Substituting these values, we have the following:
T2 = (2v * 300)/v
T2 = 600k
For AlCl3 to be a Lewis acid, it would have to react in such a way that it accepted a lone pair from some other atom or molecule from a Lewis base.AlCl3 has an electron-deficient aluminum atom. It has only six electrons in its valence shell. It readily accepts electrons from other atoms, in an attempt to get a full valence shell of eight electrons.
