Cotton is opaque. Opaque objects do not let light pass through. You can't see through the objects that are opaque.
Answer:
Kd = [Ag⁺] × [NH₃]² / [Ag(NH₃)₂⁺]
Explanation:
Let's consider the dissociation reaction of the complex ion Ag(NH₃)₂⁺.
Ag(NH₃)₂⁺(aq) ⇄ Ag⁺(aq) + 2 NH₃(aq)
The dissociation constant, Kd, is the equilibrium constant for the dissociation of the complex ion, that is, it is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients.
The dissociation constant for this reaction is:
Kd = [Ag⁺] × [NH₃]² / [Ag(NH₃)₂⁺]
Answer:
I think the answer is 2..
Explanation:
As it is known that non-electrolytes do not dissociate. Therefore, molarity of such a solution is equal to the osmolarity of solution.
As, molar mass of ethanol = 46.07 g/mol
Therefore, no. of moles of ethanol will be calculated as follows.
No. of moles = 
=
=
mol
As, molarity is moles of solute in liter of solution. Hence, molarity of ethanol is as follows.
Molarity = 
= 
=
mol/L
Since, for the given solution Molarity = osmolarity
Thus, we can conclude that osmolarity of .00001 grams (0.1 mg%) of ethanol in 1 L is
osmol/L.
