Answer 1

Explanation:

Heat is evolved during the

reaction between HCl and NaCl because it is an exothermic reaction

HCl + Na = NaCl + H2(EVOLUTION OF H2)

This is also an example of displacement reaction and also

Acid+ Metal(reactive than hydrogen) gives Salt along with evolution of hydrogen gas)
