Benzene is the simplest example of the aromatic compound
Firstly, we want to explain what is the meaning of aromaticity?
the aromaticity is called on any compound which has cyclic shape and has a resonance. Resonance is delocalization of the electrons (which form the double bond) in the molecules, in other words, the double bond moves through the compound by the movement of electrons which leads to increasing the stability of the compound by this process which called resonance. The resonance may occur in open or cyclic compounds, and if it occurs in cyclic compounds, these compounds are called aromatic compounds. So, the benzene considered to be the simplest aromatic compound where it is not only has a resonance in a cyclic ring but also it was the first aromatic compound discovered and also, the most common aromatic compounds are derivatives of it (benzene).
Answer:
The equilibrium constant Kp for this reaction is 0.0030
Explanation:
Step 1: Data given
Partial pressure at the equilibrium:
pHCl = 76.9 atm
pO2 = 66.3 atm
pCl2 = 40.7 atm
pH2O = 65.1 atm
Step 2: The balanced equation
4 HCl(g) + O2(g) → 2 Cl2(g) + 2 H2O(g)
Step 3: Calculate the equilibrium constant Kp
Kp = ((pH2O²)*(pCl2²)) /(pO2)*(pHCl^4))
Kp = (65.1²*40.7²) / (66.3*(76.9^4))
Kp = 0.0030
The equilibrium constant Kp for this reaction is 0.0030

A physical change is something that could be reverted back to its original form, while a chemical change is something that could not be reverted back when changed.
ex of physical change: ice - can be melted and then freeze to solid again
ex of chemical change: change of color, like adding food coloring in something and you cannot take out the color again
