Answer:
pls keep the question clear.
Answer:
Molality, Solvent, Solute, Mole fraction, Molarity.
Explanation:
The expression of concentration that provides the moles of solute per kilograms of solvent is Molality. This in the only expression referred to the solvent.
A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the Solvent is water. When water is present, it is usually considered the solvent.
A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the Solute is sodium chloride. There can be 1 or more solutes in a solution.
If you place 5 moles of sodium chloride and 4 moles of sucrose into 11 moles of water, the Mole fraction of sodium chloride would be 0.25. The mole fraction is equal to the moles of a substance divided by the total number of moles.
A way to express concentration that provides the moles of solute per liter of solution is Molarity.
Br₂ + FeBr₃----->Br-Br-FeBr₃
In this reaction, FeBr₃, is a electron-deficient species that is it act as a lewis acid.
While Br₂, donates its electron to FeBr₃.
Br₂, act as a electrophile while FeBr₃ is a lewis acid.
Futher if Br₂, undergoes a reaction an aromatic ring , then that ring will attack Br₂, and it acts as a electrophile.
