Answer the following Questions :

1.Compare the properties of a typical metal and a non-metal on the basis of the following. Fill in Column A, B.

PropertiesA MetalB Non- metalElectronic configuration??Nature of oxides??Oxidizing or reducing action??Conduction of heat and electricity??

2.Name the following :1) A molten metal that catches fire in chlorine gas and gives off white fumes2) A metal that forms two types of oxides and rusts in moisture; write their formulae also3) A metal used in hot water systems4) A metal used in long distance cables wires5) A metal added to gold to harden it

3.A copper plate was dipped in AgNO3solution. After certain time silver from the solution was deposited on the copper plate. State the reason why it happened. Give the chemical equation of the reaction involved.

4.An element X on reacting with oxygen forms an oxide X2O. This oxide dissolves in water and turns blue litmus red. State whether element X is metal or a non-metal.

5.Metals replace hydrogen from acid, whereas non-metals do not. Why?

6.Why are the two non-metals, carbon and hydrogen are important chemical reference points with regard to the method of metal extraction and reactivity towards acids.

7.a) What is the behaviour of magnesium when it is heated and steam is passed over it? Represent the equation. b) Can carbon dioxide react with magnesium?

8.A zinc rod was kept in a glass container having CuSO4solution. On examining, it was found that the blue colour of the solution had faded. After few days when the zinc rod was taken out of the solution, a number of small holes were noticed in it. State the reason and give equation of chemical reaction involved.
