Question 2 of 30Which of the following is a heterogeneous mixture?A.Rubbing alcoholB.Gold alloyC.SaltwaterD.PaintSUBMITarrow_backPREVIOUS

To determine which of the options is a heterogeneous mixture, let's analyze each one:

1. Rubbing Alcohol: This is a homogeneous mixture of isopropyl alcohol and water, appearing uniform throughout.

2. Gold Alloy: Alloys are usually homogeneous mixtures, where metals are mixed together to form a uniform material.

3. Saltwater: This is a homogeneous mixture because the salt dissolves completely in the water, resulting in a uniform solution.

4. Paint: Paint typically does not have a uniform consistency; it can contain pigments, solvents, and additives that are not evenly distributed, making it a heterogeneous mixture.

Final Answer

D. Paint is a heterogeneous mixture.
