Four metals P, Q R and S are all obtained by the reduction of their oxides with carbon. Metal P is used to form a thin layer over the sheets of metal S to prevent its corrosion. Metal Q is used for electroplating tiffin boxes made of metal S whereas metal R is used in making car batteries. Metals Q and R form an alloy called solder. What are metals P, Q R and S? How have you arrived at this conclusion?
Metal P is zinc; Metal Q is tin; Metal R is lead; Metal S is iron; Metal P (zinc) is used to form a thin layer on metal S (iron) to prevent its corrosion; Metal Q (tin) is used for electroplating tiffin boxes made of metal S (iron); Metal R (lead) is used in making car batteries; Metals Q (tin) and R (lead) form an alloy called solder.

PREVIOUSWhen an object made of metal A is kept in air for a considerable time, it loses its shine and becomes almost black due to the formation of a layer of substance B. When an object made of another metal C is kept in damp air for a considerable time, it gets covered with a green layer of substance D. Metal A is the best conductor of electricity whereas metal C is the next best conductor of electricity. (a) What is metal A? (b) What is metal C? (c) Name the substance B. (d) Name the substance D. (e) What type of chemical can be used to remove the green layer from metal C and clean it? Why?NEXTA black metal oxide X02 is used as a catalyst in the preparation of oxygen gas from potassium chlorate. The oxide XO2 is also used in ordinary dry cells. The metal oxide XO2 cannot be reduced satisfactorily with carbon to form metal X. (a) Name the metal X. (b) Name the metal oxide XO2 (c) Which reducing agent can be used to reduce XO2 to obtain metal X? (d) Name another metal which can also be extracted by the reduction of its oxide with the above reducing agent.
