(a) Metals are malleable and can be easily drown into sheets by hitting with a hammer. On the other hand, if we beat non-metals they break down, and they cannot be drawn into sheets as they are non-malleable. Metals of good conductors of electricity hence they make bulb when you connect metals with a battery, wire and bulb. Similarly, If non-metals are bad conductors of electricity in chance they fail to lit up the bulb on connecting with wire and battery.
(b) These experiments can be helpful to demonstrate the malleability and electric conductivity of the metals and non-metalsAnswered by Shivani Kumari | 1 year ago
A man went door to door posing as a goldsmith. He promised to bring back the glitter of old and dull gold ornaments. An unsuspecting lady gave a set of gold bangles to him which he dipped in a particular solution. The bangles sparkled like new but their weight was reduced drastically. The lady was upset but after a futile argument the man beat a hasty retreat. Can you play the detective to find out the nature of the solution he had used?
