# How does zinc react with concentrated hydrochloric acid?

$Z n \left(s\right) + 2 H C l \left(a q\right) \rightarrow Z n C {l}_{2} \left(a q\right) + {H}_{2} \left(g\right) \uparrow$
The (s) and (g) stand for $\text{solid}$ and $\text{gas}$. The (aq) stands for the $\text{aquated}$ ion. For $Z {n}^{2 +} \left(a q\right)$, this is probably ${\left[Z n {\left(O {H}_{2}\right)}_{6}\right]}^{2 +}$, a zinc ion surrounded by, AQUATED by, 6 water molecules.
