Question Description
When a silvery grey powder of a solid (A) is mixed with a powder of solid (B) no reaction occurs. But if the mixture is ignited and lighted using magnesium ribbon a reaction occurs with the evolution of a large amount of heat forming product (C) which settles down as liquid metal and the solid product (D) formed floats on the liquid (C). (C) in solid form reacts with moisture to form rust. The amount of heat generated during the reaction is so high that the reaction is used in welding of electric conductors, joints in railway tracks. Based on this information, answer the questions.The reaction in which heat is generated is called as:a)Exothermic reactionb)Endothermic reactionc)Decomposition reactiond)Precipitation reactionCorrect answer is option 'A'.
