Ans. Sodium is highly reactive metal. It reacts with oxygen in air at room temperature, the reaction is highly exothermic. To prevent this sodium is kept preserved under kerosene. Ans. Zinc is more reactive than iron, hence when added‘ to iron (II) sulphate, it can displace iron metaliand the colour of solution fades from green to colourless due to formation of zinc sulphate.
