Potassium sulfide, also
known as dipotassium monosulfide, consists of two potassium ions bonded to a
sulfide atom, rendering the chemical formula K2S.<span>Rarely
found in nature due to its high reactivity with water, potassium sulfide is
refined from the more common potassium sulfate (K2SO4) and is used in many
industries</span>
The concentration of the acid decreases
Answer:
Intermolecular forces are much weaker than the strong covalent bonds within the molecules. ... Very little energy is needed to overcome the intermolecular forces, so simple molecular substances usually have low melting and boiling points. They are often liquids or gases at room temperature
Complete Question

Answer:
The concentration of high-pressure side is
Explanation:
From the question we are told that
The thickness of the polyethylene is
The temperature is
The flux is
The concentration on the low-pressure side is
The initial diffusivity is
The activation energy for diffusion is
Generally the diffusivity of the oxygen at 600 K can be mathematically evaluated as
substituting values
Generally the flux is mathematically represented as
Where is the concentration of oxygen at the higher side
So
substituting values
