Answer 1

Question :

Differentiate between :

• Metal & Non - metal
• Manure & Fertilizer

Answer :

|| ★ || Metals & Non - Metals || ★ ||

Metals :

• Conduction of electricity
• Shiny
• Conduction of heat
• Malleable (beaten into sheets)
• Ductile (beaten into wires)
• Sonorous (make sound when struck)
• Highly reactive
• Occur as bases
• Liberate Hydrogen gas during reaction .

Examples :

Iron , Gold , Silver , Aluminium

Non - Metals :

• No conduction of electricity
• No conduction of heat
• Cannot be beaten into sheets
• Cannot be brought down into wires
• Don't produce any sound when struck.
• Less reactive
• Form Compounds

Examples :

Carbon , Phosphorus , Nitrogen

|| ★ || Manure & Fertilisers || ★ ||

Manure :

• Manure is the the naturally made compost kind of thing that is used to aid the growth of plants .

• It is made up of dead and decaying matter .

• Highly nutritious for plants as well as environment friendly .

• Manure is even pocket friendly for the farmer as if he has any extra produce he can use that to make manure .

• May not fulfill the need of a specific nutrient .

Fertilizers :

• Supplementary nutrition added to plants which are chemically synthesized in factories.

• Not environment friendly . It seeps down into the ground with water to pollute groundwater .

• Can fulfill a particular need for a specific nutrient.
