So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward.
We see that the molar ratio of sulfur to water is:
3 : 2
We first compute the moles of water:
moles = mass / Mr
moles = 37.4 / 18
moles = 2.08
By the ratio, moles of sulfur:
3.12
Mr sulfur = 64
mass = 3.12 x 64
mass = 199.7 grams
Explanation:
Formula to calculate standard electrode potential is as follows.
= 0.535 - 1.065
= - 0.53 V
Also, it is known that relation between and K is as follows.
ln K =
Substituting the given values into the above formula as follows.
ln K =
=
ln K = -41.28
K =
=
Thus, we can conclude that the value of the equilibrium constant for the given reaction is .
