Is Graphite a metal or non-metal
Non-Metal
Name a non-metal which is good conductor of electricity
Graphite
Iron+Oxygen=

Magnesium Oxide
Which Metal does not react with Water
Gold
Which metal is used to make wires
Copper
Which metal is stored in kerosene and why?
Sodium because it is highly reactive with water and oxygen
Basic in Nature as it turns red litmus paper blue/turmeric indicator red.
How can we prevent iron doors and windows from catching rust and why?
Iron catches rust when reacts with Oxygen and Water. Painting it will can protect it from Oxygen and Water. Hence, protecting iron from catching rust
Why do we have switches made of plastic
Plastic is made from non-metal which is a bad conductor of electricity. Hence plastic switches prevent us from catching current.
