6. How can you prove that water is a compound?
7. How can we convert saturated solution into unsaturated by
heating?
9. Show the different types of colloids with examples.
10. What is Tyndall effect?
Answers
Answer:
6. A compound forms whenever two or more atoms form chemical bonds with each other. The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound.
7. Its easy to convert. Just u must keep in mind, the solubility of the solute in the solvent is directly proportional to that of the temperature, so increasing the temperature of the solution will make a saturated solution unsaturated. And the easiest way is, just to add more solvent.
9. Based on the physical state of the dispersion medium and of the dispersed phase, colloids can be classified into:
Foam.
Solid Foam.
Aerosol.
Emulsion.
Gel.
Solid Aerosol.
Sols.
Solid sols.
10. . Tyndall Effect , The earth's atmosphere is a mixture of many minute particles such as smoke, water droplets, dust etc. When a beam of light strikes these fine particles, the path taken by that beam becomes visible. Light gets reflected continuously by these particles and then reaches us.
