The reaction of iron (III) oxide with heated aluminum is a displacement reaction which is highly exothermic in nature. The amount of heat evolved is so large that the metals are produced in the molten state due to which this reaction is used to join cracked machine parts. \[\ce\]

(a) Write method will you use to reduce the following ? Explain by giving a suitable example. (i) Oxides of less reactive metals (ii) Oxides of moderately reactive metals (iii) Oxides of highly reactive metals. (b) The reaction between metal 'X' and F e 2 O 3 is highly exothermic and is used to join railway tracks. (i) Identify metal 'X' and name the reaction. (ii) Write the chemical equation of its reaction with F e 2 O 3. A metal X is used extensively in making aeroplane bodies as it is light in weight it is also used in extraction of metals by displacement reaction. The metal obtained during one such displacement is a molten metal as the reaction involved is hightly exothermic. The reaction mentioned above is used in joining railway tracks. a. Identify the metal X. b. What is the reaction mentioned above called? c.Write the chemical reaction for the above reaction.
