Answer:
m = 190. g MgCl2
Explanation:
Use a molar ratio to get the # of moles MgCl2 produced from 4.00 mol of HCl:
4.00 mol HCl × (1 mol MgCl2/2 mol HCl) = 2.00 mil MgCl2
So 2.00 moles of MgCl2 will be produced. To find the mass in grams, use the molar mass of MgCl2:
2.00 mol MgCl2 × (95.211 g MgCl2/1 mol MgCl2)
= 190. g MgCl2
Answer:
No
Explanation:
The stronger the intermolecular forces the molecules tend to stay in the liquid phase. Compounds with weak intermolecular forces are more volatile and more molecules overcome those forces to pass to the gas phase.
Explanation:
It is given that possible number of ways the Cl and Br can be absorbed initially are 100.
S, possible number of ways by which Br can be desorbed is as follows.

Now, we will calculate the change in entropy as follows.

where,
= Boltzmann constant = 
= change in entropy
Therefore, we will calculate the change in entropy as follows.

= 
= 
= 
Thus, we can conclude that the change in entropy is
.
