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.

Signaling: Calcium and Calmodulin - Chemistry LibreTexts
This calcium surge could be due to intracellular G-proteins that induce the rough and smooth reticulum to release calcium, or the calcium ions could be brought in from the extracellular space. In the case of calmodulin, it is usually responding to calcium being brought into the cell from the outside, which occurs during processes such as nerve signaling (Bertini et. al. 637).
