Question

which choice is a mixture?
water
sugar
salad
potassium

Explanation:

A mixture is a combination of two or more substances that retain their individual properties. Water (\(H_2O\)) is a compound, sugar (e.g., \(C_{12}H_{22}O_{11}\)) is a compound, and potassium (\(K\)) is an element. Salad, however, is made up of different ingredients (like vegetables, dressings, etc.) that are not chemically bonded, so it is a mixture.

Answer:

salad
