The reaction of an acid and a metal gives:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. hydrogen gas and salt.
The reaction between an acid and a metal typically produces hydrogen gas and a salt. This is a type of single displacement reaction where the metal displaces hydrogen ions from the acid.
For example, when zinc (a metal) reacts with hydrochloric acid, the reaction proceeds as follows:
Zn(s) + 2HCl(aq) → ZnCl₂(aq) + H₂(g)
