1.	name the reaction used in joining railway tracks and name the obtained metal
Answer» Thermite is the chemical that is used in welding of railway tracks. It is normally a mixture of iron oxide and aluminium metal. When reacted it, Aluminium reduces iron oxide to iron and itself gets oxidised i.e. a redox reaction occurs Fe2O3+ 2 Al → 2 Fe + Al2O3 Due to the exothermic nature the reaction, iron is obtianed in molten form and can be used for welding of the railway tracks.

Answer»

Thermite is the chemical that is used in welding of railway tracks. It is normally a mixture of iron oxide and aluminium metal.

When reacted it, Aluminium reduces iron oxide to iron and itself gets oxidised i.e. a redox reaction occurs

Fe2O3+ 2 Al → 2 Fe + Al2O3

Due to the exothermic nature the reaction, iron is obtianed in molten form and can be used for welding of the railway tracks.
