So 6.02*10^22 is avogadro constant, which is the amount of atoms in one mole. If you look Xenon up in the periodic table you will find it's mass given <span>131,293, which is grams per 1 mole.

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
That would be 23.5 degrees
Answer:
B- Iodine
Explanation:
Using the periodic trends, electronegativity (electron affinity) goes down as you go down a period. This is due to the atom gaining new shells when going down each period, resulting in a weakened attraction force between the nucleus and the electrons in the cloud. In other words. as more shells are added, the weaker the atom's affinity for electrons are and the less electronegative it is. As a result, Iodine would have the weakest attraction for electrons in a bond with Calcium as it is the furthest down in the periodic table.
Answer:
A
Explanation:
The book encountered friction which turned some of the energy into heat.
