Question

which of the following is a heterogeneous mixture? *
air
steel
water with dissolved salt
soil
which of the following is a homogeneous mixture? *
salt dissolved in water
beef stew
sand and water
soil

Explanation:

A heterogeneous mixture has visibly different parts and non - uniform composition. Soil contains various components like rocks, organic matter, and minerals that are not evenly distributed. A homogeneous mixture has a uniform composition throughout. Salt dissolved in water forms a solution where the salt is evenly dispersed at a molecular level. Air is a homogeneous mixture of gases, steel is a homogeneous alloy, and water with dissolved salt is a solution (homogeneous). Beef stew, sand and water, and soil are heterogeneous.

Answer:

First question: soil
Second question: salt dissolved in water
