# Write a balanced equation for the following, including physical states: Magnesium + Hydrochloric Acid > Magnesiumchloride + Hydrogen gas Mg + HCl > MgCl + H Is that it? I feel like I'm missing something.

$M {g}_{\left(s\right)} + 2 H C {l}_{\left(a q\right)} \rightarrow M g C {l}_{2 \left(a q\right)} + {H}_{2 \left(g\right)} \uparrow$

#### Explanation:

Some small details you missed are that magnesium chloride is $M g C {l}_{2}$ and that hydrogen gas is ${H}_{2}$.

So it should be:

$M {g}_{\left(s\right)} + H C {l}_{\left(a q\right)} \rightarrow M g C {l}_{2 \left(a q\right)} + {H}_{2 \left(g\right)} \uparrow$

When you balance it, it will become:

$M {g}_{\left(s\right)} + 2 H C {l}_{\left(a q\right)} \rightarrow M g C {l}_{2 \left(a q\right)} + {H}_{2 \left(g\right)} \uparrow$
