Assuming that the gas acts like an ideal gas, we can
calculate for the final volume using the ideal gas law:
PV = nRT
Where P = pressure, V = volume, n = number of moles, R = gas
constant, and T = temperature
Assuming that P, n, and R are constant throughout the
process, we can define another constant K:
V / T = K where
K = nR / P
Equating the initial and final states:
Vi / Ti = Vf / Tf
Substituting the given values:
11.5 cm^3 / 415 K = Vf / 200 K
Vf = 5.54 cm^3
Gas. Molecules in gas are able to move and vibrate around each other more freely than the molecules in liquids and/or solids due to the great amount of space in between them. Hope this helps! :)
Answer:N

-----> N
H
3
Let us balance this equation by counting the number of atoms on both sides of the arrow.
N
2
+
H
2
-----> N
H
3
N=2 , H=2 N=1, H=3
To balance the number of N atom on Right Hand Side (RHS) , I will add one molecule of N
H
3
on RHS
N
2
+
H
2
-----> 2N
H
3
N=2 , H=2 N=2 , H= 6
To balance the number of H atoms on Left Hand Side (LHS) , I will add two molecules of
H
2
on LHS
N
2
+ 3
H
2
-----> 2N
H
