Which is an example of a mixture

A mixture is two or more substances that have been combined together but each substance is not changed chemically.

Examples of mixtures include:

1. Sea water. This is a mixture of water and various salts.

2. Gunpowder. This is a mixture of potassium nitrate, suilfur and carbon

3. Crude oil. This is a mixture of organic compounds, mainly hydrocarbons.

4. Ink. This is a mixture of colored dyes which can be separated using  chromatography.

5. Dry air. Air is a mixture of nitrogen,oxygen, argon, carbon dioxide, neon and tiny traces of other gases.

anaphase.

hope this !

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
