1. Saltwater: A mixture of salt and water is a homogeneous mixture. The salt dissolves in the water and becomes evenly distributed throughout the solution, so that the composition of the mixture is the same throughout.

2. Air: Air is a homogeneous mixture of several gases, including nitrogen, oxygen, and argon. The gases are evenly distributed throughout the atmosphere, so that the composition of air is the same everywhere.

3. Brass: Brass is a homogeneous mixture of copper and zinc. The copper and zinc atoms are evenly distributed throughout the alloy, so that the composition of brass is the same throughout.

4. Gasoline: Gasoline is a homogeneous mixture of hydrocarbons. The hydrocarbons are evenly distributed throughout the fuel, so that the composition of gasoline is the same throughout.

5. Milk: Milk is a homogeneous mixture of water, proteins, fats, and carbohydrates. The components of milk are evenly distributed throughout the liquid, so that the composition of milk is the same throughout.
