a. The concentration of a solution is the amount of solute present per unit volume or per unit mass of the solution/solvent.
b. The particles of a suspension are called the dispersed phase.
c. On heating of two elements in a mixture strongly we get a compound, which has totally different properties as compared to the combining elements.

1.Only a
2.Only b

Answer 2

5.All of these is correct option.

1. The concentration of solution can be calculated in terms of molarity and molality.
2. Molarity is the amount of solute present per unit volume of solution and molality is amount of solute per unit mass of the solvent.
3. Dispersed phase refers to solute particles while dispersion medium contains dispersed solute.
4. The compound formed can not be seperated by physical means but only by chemical reaction.
