Question

For the reaction, Ni (s) and HCl (aq), write the molecular, complete ionic and net ionic equations. Note: most likely charge on the nickel cation is +2.

Answer 1

Step-by-step explanation:

Balanced Molecular reaction

`Ni(s) + 2HCl(aq)` →
`NiCl2(aq) +H2(g)`

Complete ionic reaction

`2 H^+ (aq) + 2 Cl^- (aq) + Ni (s)`→
`Ni^2+ (aq) + 2 Cl^- (aq) + H2 (g)`

Net ionic reaction

`Ni(s)+ 2H^+(aq)`→
`Ni^2+(aq) + H2(g)`
