gpt
HCl (aq) + Ni (s) --> NiCl2 (aq) + H2 (g)
Explanation: This is a chemical reaction in which hydrogen chloride (HCl) reacts with nickel (Ni) to form nickel chloride (NiCl2) and hydrogen gas (H2). This reaction illustrates the principles of acid-metal reactions that produce ionic compounds and hydrogen gas.
