Question

Which of the following is a homogeneous mixture?

(a) a bronze sword from ancient Greece;
(b) sweat;
(c) Nile River water;
(d) gasoline;
(e) compressed air in a scuba tank.

Answer 1

Compressed air in a scuba tank is a homogeneous mixture.

Step-by-step explanation:

The correct answer is option (e) compressed air in a scuba tank. Compressed air in a scuba tank is a homogeneous mixture. A homogeneous mixture, also known as a solution, is a mixture where the different components are uniformly distributed and cannot be easily distinguished. In the case of compressed air in a scuba tank, the oxygen, nitrogen, and other gases that make up the air are evenly mixed throughout the tank, resulting in a homogeneous mixture.
