During the reaction of some metals with dilute hydrochloric acid, the following observations were made.
(c) The reaction of sodium metal is found to be highly explosive
d) Some bubbles of gas are seen when lead (Pb) is reacted with the acid.

Answer: c) Sodium is a highly reactive metal, and when it reacts with atmospheric oxygen, it produces an exothermic reaction, which raises the temperature of the surrounding environment.

d) Hydrogen gas is produced when lead reacts with acid and is responsible for the formation of bubbles in the solution.
