During today’s experiment we will produce hydrogen gas (H2) using zinc metal (Zn(s)) and hydrochloric acid (HCl). Which is a balanced net ionic equation illustrating this process?
A. Zn (s) + 2 HCl (aq) --> Zn2+ (aq) + H2 (g) + 2 Cl- (aq)
B. Zn (s) + 2 H+ (aq) --> Zn2+ (aq) + H2 (g)
C. Zn (s) + 2 H+ (aq) --> Zn2+ (aq) + 2 NaCl (aq)
D. Zn (s) + 2 HCl (aq) --> Zn2+ (aq) + HCl (aq)
