You don't have to worry about converting to moles and back to liters. You need to know about Gay-Lussac's law of combining volumes. Coupled with Avogadro's law which says that the moles of gas are proportional to the volume, all we have to do is:
2H2(g) + O2(g) -> 2H2O(g)
2L ..........1L ..........2L
7.25L .....3.63L .....7.25L
The only work is dividing 7.25 by 2.
Answer:
the ability of a compound to dissolve
Explanation:
salt dissolves in water so it would be soluble.
oil does not dissolve in water so it is not soluble
Solution :
<u>Explanation 1 </u>:
Spontaneity of the reaction is based on two factors :
-- the tendency to acquire a state of minimum energy
-- the energy of a system to acquire a maximum randomness.
Now, since there isn't much difference in the bond enthalpies of B-F and B-Cl. So, we can say the major driving factor is tendency to acquire a state of maximum randomness.
<u>Explanation 2 </u>:
A system containing the 
B halides has a 
than a system of 
and 
.
It has the same number of 
, but more distinguishable kinds of 
, hence, more microstates and higher entropy.
Because they could have an explosive reaction and could possibly hurt you
I wanna say false, but I’m sorry if I’m wrong :(
