Some commonly used metals are given in the table below. Write at least one use each of them. Sl No. Metals Uses 1. Iron 2. Aluminium 3. Zinc 4. Copper 5. Silver 6. Mercury

Metals are usually lustrous in their appearance, and they are malleable, ductile and good conductors of heat and electricity. This is the reason why they have got so many uses. Therefore, the given table can be completed as, Sl No. Metals Uses 1. Iron In the manufacture of steel, used for making alloys, etc. 2. Aluminium Aircraft bodies, aluminium foils, etc. 3. Zinc Galvanisation, for making alloys, etc. 4. Copper Electric wires, vessels, etc. 5. Silver Ornaments, electrodes, etc. 6. Mercury It is mainly used in thermometers.

Some commonly used compounds are given in the table below. The elements which constitute them are also written against them. List at least one use of each of them. Sl No. Compounds Elements Uses 1. Urea Nitrogen, carbon, hydrogen, oxygen 2. Washing soda Sodium, carbon, oxygen 3. Kerosene Carbon, hydrogen 4. Sugar Carbon, hydrogen, oxygen 5. Marble Calcium, carbon, oxygen

Urea is a useful waste product of many living organisms. Washing soda is an alkaline material that has good cleaning properties. Kerosene is a petroleum product that is majorly used as a fuel. Sugar is a sweetening agent. Marble has many uses in the construction field. Sl No. Compounds Elements Uses 1. Urea Nitrogen, carbon, hydrogen, oxygen Used as a nitrogen releasing fertiliser. 2. Washing soda Sodium, carbon, oxygen Used in the manufacture of soap, detergents, etc. 3. Kerosene Carbon, hydrogen Used as a liquid fuel, used in kerosene lamps, etc. 4. Sugar Carbon, hydrogen, oxygen Used as a sweetening agent in foods and beverages. 5. Marble Calcium, carbon, oxygen Used for making architecture, sculpture, paints, etc.
