Milk is an example of solid emulsion. Hence, option D is correct.
<h3>What is emulsion?</h3>
An emulsion is defined as a colloid consisting of two or more non-homogenous type of liquids in which one of the liquid contains the dispersion of the different form of liquids.
Emulsion consist of a dispersion of two liquids that are immiscible with each other.
One of the liquids act as the dispersion medium and the other will act as the dispersed phase.
Emulsions are colloids in which both the dispersed phase and dispersion medium are liquids.
Types of Emulsion:
- Oil in water (O/W)
- In this type of emulsion, the oil will be the dispersed phase and water will be the dispersion medium.
- Example of o/w emulsion is milk.
2. Water in oil (W/O)
- In this type, water will be the dispersed phase and oil will be the dispersion medium.
- Margarine is an example of water in oil emulsion.
Milk is an example of solid emulsion. Hence, option D is correct.

0.58 is the molarity of 29.9 g of MgS in 911 mL of solution.
Define the molarity of a solution.
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.
Given data:
Volume of solution = 911 mL=0.911L
Given the mass of MgS = 29.9 g
Molar mass of MgS = 56.38 g/mol
Moles of MgS = 0.5303299042
Molality = 0.5821403998=0.58
Hence, 0.58 is the molarity of 29.9 g of MgS in 911 mL of solution.

Answer:
The mixture 1/ must be homogeneous where there is one or more dissolved salts; 2/ should only contain one liquid component.
Explanation:
This method drives off the liquid components from the solid components. The process typically involves heating the mixture until no more liquid remains. Prior to using this method, the mixture should only contain one liquid component, unless it is not important to isolate the liquid components. This is because all liquid components will evaporate over time. This method is suitable to separate a soluble solid from a liquid.
Note : In many parts of the world, table salt is obtained from the evaporation of sea water. The heat for the process comes from the sun.
