during the reaction of some metals with dilute hydrochloric acid, following observations were made. (A) Silver metal does not show any change, (B) The temperature of the reaction mixture rises when aluminium (Al) is added, (C) The reaction of sodium metal is found to be highly explosive, (D) Some bubbles of a gas are seen when when lead (PV) is reacted with the acid. Explain these observations giving suitable reasons

Explanation:
1. Silver is a noble metal and hence it does not react with dilute hydrochloric acid
2. Reaction between hydrochloric acid and aluminium is exothermic.
3.Sodium is at the top ranking in reactivity series of metals, which means sodium is a highly reactive metal. Tat is why, the reaction between sodium and hydrochloric acid is highly explosive.
4.zinc granules that effervescence is seen when acid is poured over zinc garnules. Same process takes place in reaction between lead and hydrochloric acid.
