Q119P - Chemistry: Molecular Nature Of Matter And Change

Question

Classify each of the following as a compound, a homogeneous mixture, or a heterogeneous mixture: (a) distilled water; (b) gasoline; (c) beach sand; (d) wine; (e) air.

Step-by-Step Solution

Answer

The classification for the compound as,

a)Distilled water is a compound

b)Gasoline is a Homogeneous mixture

c)Beach sand is a Heterogeneous mixture

d)Wine is a Homogeneous mixture
e)Air is a Homogeneous mixture

Step 1: Finding the classification for distilled water

Distilled water does not contain any dissolved ions and it is made up of hydrogen and oxygen (combined in a fixed ratio), thus distilled water is a compound.

Step 2: Finding the classification for gasoline

Gasoline is a mixture of various organic compounds. The compounds can be distributed uniformly, thus it is a homogeneous mixture.

Step 3: Finding the classification for Beach sand

The disintegrated rocks, shells and another mixture is Beach sand. There are many compounds mixed and one cannot sure that uniformly spread. Thus, beach sand is a Heterogeneous mixture.

Step 4: Finding the classification for wine

Wine is considered a homogeneous mixture as it is a uniform mixture of ethanol and water.

Step 5: Finding the classification for air

Air is a mixture of various gases and all the gases are uniformly distributed throughout hence, the air is a homogeneous mixture.
