I believe this would be Avogadro's law which states ''Equal volumes of all gases, at the same temperature and pressure, have the same number of molecules regardless of their chemical nature and physical properties.''
It is an example of physical change. The molecules are not changing, so it is not chemical, and a physical property is something that a physical thing has.
Answer:
The reason that that elements in the same 'group' have similar chemical properties is because they have the same number of valence electrons. ... Iron when reacting in chemical reactions loses electrons from its 4s orbital instead of its d orbital
Answer: The value of the equilibrium constant Kc for this reaction is 0.088
Explanation:
where,
x = given mass
M = molar mass
= volume of solution in L
Equilibrium concentration of
=
Equilibrium concentration of
= 
Equilibrium concentration of
=
The given balanced equilibrium reaction is,
The expression for equilibrium constant for this reaction will be,
Now put all the given values in this expression, we get :
