1.	In the welding of railvvay tracks, a proper proportion of aluminium powder and iron (III) oxide arc made to react with each other at high temperature. Explain the type of reaction involved and also identify the reducing and the oxidizing agents.
Answer» SOLUTION :At high temperature aluminium reacts with iron (III) oxide. `2Al+Fe_2O_3toAl_2O_3+2Fe+"HEAT"` It is a displacement and exothermic reaction. Al ACTS as reducing AGENT as it undergoes oxidation while `Fe_2O_3` acts as oxidizing agent as it undergoes reduction.
