Question

PLEASE HELP ASAP, WILL GIVE BRAINIEST

Answer 1

Answer 1. mixture C is a heterogeneous solution.

This is because heterogeneous solution :

• scatters light- solute particles are large in size as they are partially or fully insoluble in solvent  and can be seen with naked eyes, so whenever light is passed through it ,path of light is visible.

• separates into two  different layers-presence of physical boundaries in between the  layers of solute and of the solvent.

• can be separated out by filtration- due to formation of two different layers both the layers can be separated easily with the help of filtration technique.  

Answer 2. mixture B is a solution.

Solutions are homogeneous solution and homogeneous solution:

• doesn't scatter light- due to very small size of solute particles are not visible to naked eyes, so whenever light is passed its path is not visible.
• doesn't separate out into layers-  solute particles are completely soluble in solvent so they do not form any layers.
• cant be separated out by filtration - miscibility makes it impossible to filter out the solute particles from the solvent.

Answer 2

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, sulfur 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.
