Question

Match these terms with the correct examples.

Answer 1

1. liquid solution to a. oceans
2. gaseous solution to b. clouds
Not sure about 3 and 4.
3 might be oxygen but I think that's 5. element.

Hope this helps, not sure about water and air though.

Answer 2

Answer:

           1) Liquid solution: Oceans

            2) Gaseous Solution: Air

            3) Compound:  Water

            4) Colloid: Cloud

            5) Element: Oxygen

Explanation:

                        Solutions are those mixtures which have uniform composition. The size of solute is around 1 Angstrom hence, the particles of solutes can not be seen and the interactions make the overall solution transparent.

                        Compounds are those substances which are formed chemically by the reaction of two different elements like,

                                       O₂  +  2 H₂    →    2 H₂O

                        Colloids are also mixtures but these are intermediate between true solutions and suspensions. Also, the solute size is greater than that of solute size in solutions and is about 10 Angstrom. Examples include Clouds, Fog, Moist, Aerosol sprays e.t.c.

                        Elements are those substances which either are made up of single atoms like noble gases or are molecules made up of same elements like O₂, H₂, Cl₂, N₂ e.t.c.
